  • hierarchical Addressing scheme for 6lowpan wsn
    Wireless Networks, 2018
    Co-Authors: Xiaonan Wang, Deguang Le, Hongbin Cheng
    Abstract:

    This paper proposes a hierarchical Addressing scheme for 6LoWPAN WSN and aims to reduce the Addressing cost and latency. The proposed scheme includes the Address initialization and Address maintenance algorithms. When the network starts, the Address initialization algorithm is performed. Through the Address initialization process, each node can be configured with a globally unique Address without duplication Address detection. The Address maintenance algorithm is made up of the Address Configuration sub-algorithm and the Address reclamation sub-algorithm. After the Address initialization process ends, a new node performs the Address Configuration sub-algorithm to obtain a globally unique Address from a neighbor. The Address reclamation sub-algorithm is performed to reclaim the released Addresses for reuse so that there is enough Address resources available for assignment. Finally, the proposed scheme is evaluated, and the results show that this scheme effectively reduces the Addressing delay and cost.

  • a secure ipv6 Address Configuration protocol for vehicular networks
    Wireless Personal Communications, 2014
    Co-Authors: Xiaonan Wang, Guangjie Han
    Abstract:

    This paper proposes a secure Address Configuration protocol for IPv6-based vehicular networks. In this protocol, the network architecture is proposed. In this architecture, a vehicle obtains a unique Address from a neighbor vehicle or an access point without DAD, and a leaving vehicle's Address space can be automatically reclaimed for reassignment. Based on this architecture, the Address Configuration algorithm is presented. In this algorithm, an access point or a vehicle owns the unique Address space and assigns a unique Address to a neighbor vehicle without DAD, so the Address Configuration cost and delay are lowered. The identification of a vehicle can be authenticated, so the security is achieved. This paper evaluates the performance of this protocol. The data results show that this protocol effectively improves the Address Configuration performance.

  • an Address Configuration protocol for 6lowpan wireless sensor networks based on pdad
    Computer Standards & Interfaces, 2014
    Co-Authors: Xiaonan Wang, Yuan Yang, Yufeng Yao, Hongbin Cheng
    Abstract:

    Abstract In a wireless sensor network (WSN), data collected by a sensor node need to be associated with location information in order to support real-world applications. Taking the WSN characteristics into account, this paper proposes an Address Configuration scheme based on location information and passive duplicate Address detection (PDAD). In this scheme, the network architecture based on location information is presented, and based on this architecture the Address initialization algorithm and Address maintenance algorithm are proposed. The Address initialization algorithm is performed once the network starts, and it is made up of the initialization Address Configuration sub-algorithm (IAC) and the initialization location PDAD sub-algorithm (ILPDAD). The Address maintenance algorithm is performed after the initialization algorithm is complete, and it is composed of the maintenance Address Configuration sub-algorithm (MAC) and the maintenance location PDAD sub-algorithm (MLPDAD). During the Address initialization process (Address maintenance process), a new node first uses IAC (MAC) to obtain an Address and then performs ILPDAD (MLPDAD) to ensure the Address uniqueness. Since beacon frames are employed to achieve IAC (MAC) and ILPDAD (MLPDAD), the Address Configuration cost and delay are reduced. Moreover, IAC (MAC) is based on location information and ILPDAD (MLPDAD) is based on PDAD, so there are always the sufficient Address resources for Address Configuration without Address reclamation. In this way, the extra cost and delay caused by both the Address reclamation and the Address Configuration failure are avoided. This paper evaluates the performance of this scheme, and the data results show that this scheme effectively reduces the Address Configuration delay and cost.

  • a secure ipv6 Address Configuration scheme for a manet
    Security and Communication Networks, 2013
    Co-Authors: Xiaonan Wang
    Abstract:

    We propose a secure Internet Protocol version 6 (IPv6) Address Configuration scheme for a Mobile Ad Hoc Network. The scheme presents the architecture for a Mobile Ad Hoc Network and the hierarchical IPv6 Address structure. In the architecture, a new node can acquire a unique IPv6 Address from a proxy node within one-hop scope without performing a duplicate Address detection process, and the IP Addresses occupied by failed nodes can be recovered automatically for reuse. On the basis of the hierarchical IPv6 Address structure, each proxy node can acquire a unique Address scope for assignment and assign a unique IP Address for new nodes, so the Address Configuration task is distributed around proxy nodes. In addition, the transmission scope of the control packets for Address Configuration is controlled within one-hop scope, so the Address Configuration cost is reduced, and the delay is shortened. The security of the proposed Address Configuration scheme is achieved through authentication. The paper analyzes the performance parameters of the proposed scheme and the existing schemes, and the analytical results show that the Address Configuration cost of the proposed scheme is lower and the delay is shorter.

  • method for achieving automatic Configuration of ipv6 Addresses for wireless sensor network
    2012
    Co-Authors: Xiaonan Wang
    Abstract:

    The invention provides a method for achieving the automatic Configuration of IPv6 Addresses for a wireless sensor network. In the method, the wireless sensor network is provided with four types of nodes including isolated sensor nodes, IPv6 access nodes, cluster head nodes and intra-cluster nodes, wherein one of the IPv6 access nodes and a plurality of the cluster head nodes form a dendritic structure. The wireless sensor network consists of a plurality of clusters, and each cluster comprises one cluster head node and a plurality of intra-cluster nodes. The IPv6 access nodes/cluster head nodes adopt a state-full Address Configuration scheme for recording Address assignment to allocate the IPv6 Addresses to the other cluster head nodes; the cluster head nodes adopt the state-full Address Configuration scheme for recording the Address assignment and a state-less Address Configuration scheme for random assignment to allocate the IPv6 Addresses to the intra-cluster nodes in the clusters to which the cluster head nodes belong; and when the cluster head nodes adopt the Address Configuration scheme for the random assignment to allocate the IPv6 Addresses to the intra-cluster nodes in theclusters to which the cluster head nodes belong, repeat Addresses of the allocated IPv6 Addresses are only detected in the clusters.

  • facilitating real time applications in vanets through fast Address auto Configuration
    Consumer Communications and Networking Conference, 2007
    Co-Authors: Claudio E Palazzi, Maria Fazio, Mario Gerla, S Das
    Abstract:

    Real-time applications are going to play a major role in Vehicular Ad-hoc Networks (VANETs). In this context, nodes' IP Addresses need to be automatically configured in a very small time and with a reduced need for re-Configurations. Due to the very high mobility of vehicles, however, traditional mechanisms for Address auto-Configuration fail to perform well. Aimed at solving this problem, we propose a novel Leader-based scheme that exploits the topology of VANETs and a distributed DHCP service to guarantee fast and stable Address Configuration.

  • automatic ip Address Configuration in vanets
    Ad Hoc Networks, 2006
    Co-Authors: Maria Fazio, Claudio E Palazzi, S Das, Mario Gerla
    Abstract:

    Cars' high mobility and density impede the direct utilization of traditional networking techniques and protocols in vehicular networks. In this context, automatic IP Address Configuration is a challenging and yet unexplored issue. We propose a novel scheme that exploits the topology of Vehicular Ad-hoc Networks (VANETs) and an enhanced Dynamic Host Configuration Protocol (DHCP) service with dynamically elected leaders to provide reliable and fast Address Configuration.

  • An IP Address Configuration algorithm for multi-router zeroconf networks
    Proceedings ISCC 2002 Seventh International Symposium on Computers and Communications, 2002
    Co-Authors: Cüneyt Akınlar, Udaya A. Shankar, S Mukherjee, D. Braun
    Abstract:

    Zero-Configuration (zeroconf) networks are a particular class of IP networks that do not require any user administration for correct operation. IP Address Configuration in zeroconf networks is an important problem. While there are a few proposals for IP host Configuration, a general solution for IP router Configuration, an important problem in multi-router zeroconf networks, does not yet exist. In a single-router zeroconf network, the router can easily configure by creating unique IP subnets over each of its directly attached segments. But when several such self-configuring routers are interconnected together to form a multi-router network, there is a need for (1) dynamic exchange of routing information among the routers and (2) consistent assignment of IP subnets in the network, i.e., an IP subnet can not be assigned to different segments. As new routers are added to the zeroconf network, any IP subnet conflicts must be detected and resolved. No solutions for IP Address auto-Configuration of multi-router networks exist. This paper suggests the requirements for IP Address Configuration of multi-router zeroconf networks, and proposes IP host and router Configuration algorithms to satisfy these requirements. Among the proposed algorithms is a novel routing algorithm designed by augmenting the basic distance vector routing algorithm that can solve both the problem of dynamic routing and consistent IP subnet assignment in multi-router zeroconf networks. We also show how the popular routing information protocol (RIP) can be augmented to implement the proposed routing algorithm, called the zeroconf routing information protocol (ZRIP).

  • ip Address Configuration algorithms for routerless and single router zeroconf networks
    International Symposium on Computers and Communications, 2002
    Co-Authors: Cüneyt Akınlar, Udaya A. Shankar, S Mukherjee, D. Braun
    Abstract:

    IP hosts and network infrastructure have historically been difficult to configure, requiring network services such as DHCP and DNS servers, and relying on highly trained network administrators. This need for administration has prevented IP networks from being used in many environments such as in homes, in small businesses, in impromptu networks established at conferences, construction sites, emergency relief stations, etc. With the proliferation of IP-enabled network-attached appliances and inexpensive computing devices, the demand to enable plug-and-play, easy-to-use IP networking has increased. This demand has initiated a new paradigm of IP networking called zero Configuration, or zeroconf, networking. The goal is to develop a set of zeroconf Configuration protocols to enable IP networking without manual Configuration or administration. Such IP networks are called zeroconf networks. We examine IP Address Configuration in zeroconf networks involving two network topologies: (1) A routerless network, which consists of several hosts attached to a segment having no router, (2) A single-router network, which consists of a router joining several segments together into a star-shaped topology. We suggest the requirements for IP Address Configuration, review the existing solutions, and propose new algorithms to Address their deficiencies. Finally, we present a comparison of our algorithms to existing solutions and describe when a particular Configuration method should be used.

  • aipac automatic ip Address Configuration in mobile ad hoc networks
    Computer Communications, 2006
    Co-Authors: Maria Fazio, Massimo Villari, Antonio Puliafito
    Abstract:

    We present an innovative protocol for the automatic Configuration of the IP Address in ad hoc networks. This protocol assigns unique IP Address to each node and manages possible duplicate Addresses due to the mobility of nodes in the network. It avoids the storage of large amounts of data and makes use of procedures that minimize the number of exchanged packets. The protocol also provides a new mechanism, called Gradual Merging of networks that causes the merging process of networks according to their evolution. Ns2 simulations are carried out to validate and characterize the performance of our proposed approach.

  • an ipv6 Address Configuration scheme for wireless sensor networks
    Computer Standards & Interfaces, 2012
    Co-Authors: Xiaonan Wang, Huanyan Qian
    Abstract:

    The paper proposes an IPv6 Address Configuration scheme for wireless sensor networks. The paper creates an IPv6 Address structure for sensor nodes, and based on the proposed IPv6 Address structure, the paper proposes an IPv6 Address auto-Configuration scheme. In the scheme, the transmission scope of the control packets is controlled within one-hop scope and the scheme neither records the Address allocation status nor performs the duplicate Address detection, so the Address Configuration cost is reduced and the Address Configuration delay is shortened. In addition, based on the proposed IPv6 Address structure, the paper proposes the Address recovery algorithm. From the perspectives of the Address Configuration cost and Address Configuration delay, the paper analyzes and compares the performance parameters of the proposed scheme and the existing schemes, including MANETConf, Strong DAD, LISAA and IAC. The analytical and simulative results show that the performance of the proposed scheme is better.

  • Hierarchical and low-power IPv6 Address Configuration for wireless sensor networks
    International Journal of Communication Systems, 2011
    Co-Authors: Xiaonan Wang, Huanyan Qian
    Abstract:

    The paper proposes a hierarchical and low-power IPv6-Address Configuration scheme for wireless sensor networks based on the cluster-tree architecture. In the scheme, a wireless sensor network is divided into multiple clusters and the generation algorithm of a cluster is proposed. A cluster-tree architecture for wireless sensor networks is presented and a layered IPv6 Address format for a cluster head and a cluster member is created. The stateless Address Configuration strategy and the stateful Address Configuration strategy are effectively combined to develop the IPv6 Address Configuration scheme. In the scheme, the duplicate Address detection of the IPv6 Address assigned for a cluster member is performed in the cluster where the cluster member locates, and the IPv6 Address Configuration for the cluster members in the different clusters can be carried out at the same time. The paper also Addresses the mobility of sensor nodes and their failure. From the theoretical and simulative perspectives, the paper analyzes the performance parameters, including duplicate Address detection cost, Address Configuration cost and Address Configuration delay time, of the proposed scheme, Strong DAD and MANETConf. Analytical and simulative results show that the performance of the proposed scheme is better. Copyright © 2011 John Wiley & Sons, Ltd.
