  • New Wireless Mesh Network Routing Protocol
    Computer Simulation, 2009
    Co-Authors: Ma Jian-feng
    Abstract:

    In IEEE SEE-Mesh proposal, the Routing Protocol—HWMP (Hybrid Wireless Mesh Protocol) has some problems in efficiency and expansibility. Based on proactive Routing ideal, making use of the combination characteristic of distributed and centralized Routing Protocol, a new Routing Protocol WMRP(Wireless Mesh Route Protocol) was proposed, which extended the flat Routing to the class Routing architecture like the ip Routing architecture in data link layer. Through the network simulation and performance evaluation, the result shows that the WMRP has advantages in performance over the HWMP. The efficiency and expansibility of Routing Protocol are improved greatly.

  • two tier secure Routing Protocol for heterogeneous sensor networks
    IEEE Transactions on Wireless Communications, 2007
    Co-Authors: Xiaojiang Du, Mohsen Guizani, Yang Xiao, Hsiaohwa Chen
    Abstract:

    Research on sensor network Routing focused on efficiency and effectiveness of data dissemination. Few of them considered security issues during the design time of a Routing Protocol. Furthermore, previous research on sensor networks mainly considered homogeneous sensor networks where all sensor nodes have the same capabilities. It has been shown that homogeneous ad hoc networks have poor fundamental performance limits and scalability. To achieve better performance, we adopt a heterogeneous sensor network (HSN) model. In this paper, we present a secure and efficient Routing Protocol for HSNs - two tier secure Routing (TTSR). TTSR takes advantage of powerful high-end sensors in an HSN. Our security analysis demonstrates that TTSR can defend typical attacks on sensor Routing. Our performance evaluation shows that TTSR has higher delivery ratio, lower end-to-end delay and energy consumption than a popular sensor network Routing Protocol.

  • on demand multicast Routing Protocol
    Wireless Communications and Networking Conference, 1999
    Co-Authors: Sungju Lee, Mario Gerla, Chingchuan Chiang
    Abstract:

    This paper presents a novel multicast Routing Protocol for mobile ad hoc wireless networks. The Protocol, termed ODMRP (on-demand multicast Routing Protocol), is a mesh-based, rather than a conventional tree-based multicast scheme and uses a forwarding group concept (only a subset of nodes forwards the multicast packets via scoped flooding). It applies on-demand procedures to dynamically build routes and maintain multicast group membership. ODMRP is well suited for ad hoc wireless networks with mobile hosts where bandwidth is limited, topology changes frequently, and power is constrained. We evaluate ODMRP's scalability and performance via simulation.

  • A wireless hierarchical Routing Protocol with group mobility
    WCNC. 1999 IEEE Wireless Communications and Networking Conference (Cat. No.99TH8466), 1999
    Co-Authors: G Pei, X Hong, Mario Gerla, C.-c. Chiang
    Abstract:

    In this paper we present a hierarchical Routing Protocol in a large wireless, mobile network such as found in the automated battlefield or in extensive disaster recovery operations. Conventional Routing does not scale well to network size. Likewise, conventional hierarchical Routing cannot handle mobility efficiently. We propose a novel soft state wireless hierarchical Routing Protocol-Hierarchical State Routing (HSR). We distinguish between the “physical” Routing hierarchy (dictated by geographical relationships between nodes) and “logical” hierarchy of subnets in which the members move as a group (e.g., company, brigade, battalion in the battlefield). HSR keeps track of logical subnet movements using home agent concepts akin to Mobile IP. A group mobility model is introduced and the performance of the HSR is evaluated through a detailed wireless simulation model

  • A Threshold-based Hybrid Routing Protocol for
    2007
    Co-Authors: Jing Xie, Luis Gironés Quesada, Yuming Jiang
    Abstract:

    Mobile ad hoc networking technologies have in- creasingly been applied to civilian applications, and the require- ments of providing better services in mobile ad hoc networks (MANETs) are growing, accordingly. However, the natures of MANET, which are highly dynamic topologies and possibly high bit error rate of links, raise many challenges in developing efficient, reliable and scalable Protocols for MANETs. Espe- cially, Routing Protocols for MANETs are significantly different from traditional Routing Protocols. In this paper we propose a threshold-based hybrid Routing Protocol that supports a mobile node to selectively run the Routing Protocol based on its velocity. In addition, the proposed Routing Protocol and several typical MANET Routing Protocols are theoretically analyzed. I. INTRODUCTION A MANET is a decentralized autonomous system and consists of free nodes that can move arbitrarily. A MANET node principally consists of a router (1). To discover the network topology and deliver messages, Routing functionality has to be incorporated into the mobile node. The mobility of nodes may change the network topology rapidly and randomly with time. The dynamic topology makes the Routing Protocol design complex and difficult.
