  • 2009 Sixth International Conference on Information Technology: New Generations Supporting Stateless address Auto-configuration in IP-based Wireless Sensor Networks
    2010
    Co-Authors: Shafique Ahmad Chaudhry, Cormac J Sreenan
    Abstract:

    IP-based Wireless Sensor Networks (IP-WSN) are envisioned to play an important role in the realization of pervasive environments. Comprised of hundreds or even thousands of nodes, these networks may never undergo pre-deployment address configuration. The Stateless Autoconfiguration capability is therefore essential to the spontaneity of such pervasive networks. Recently, several address Autoconfiguration schemes have been proposed with their applications in sensor networks as well as in mobile ad-hoc networks. However, we argue that there is no singular scheme that meets the requirements of IP-WSN environments. In this paper, we discuss the requirements for Stateless auto-configuration in IP-WSN and present a hierarchical duplicate address detection mechanism for IP-WSNs. In our solution we propose Duplication Address Detection (DAD) Resolver Proxy Agents (DRPA) to act as cache service for DAD resolver to localize the DAD procedure, in order to reduce the DAD overhead traffic. We also propose algorithms to make sure that the node executing DAD procedure is always connected to the nearest DRPA. Analytical results conclude that our architecture and algorithms help reducing the traffic overhead for DAD procedure, decrease the DAD time, and save nodes ’ energy considerably in IP-WSNs

  • performance and scaling of wireless ad hoc ipv6 Stateless address Autoconfiguration under mobile gateways
    Military Communications Conference, 2007
    Co-Authors: Jeffrey Wildman, David Hamel, Ryan Measel, Dan Oakum, Steven Weber, Moshe Kam
    Abstract:

    Autoconfiguration mechanisms in general, and Stateless address Autoconfiguration in particular, are highly desirable capabilities of military mobile ad hoc networks (MANETs). However, IPv6 Stateless Autoconfiguration schemes for MANETs still have to be refined, and a convincing demonstration is needed to show that these schemes can cope with the dynamic, infrastructure-free environment wherein MANETs operate. In this paper we provide a literature survey of Autoconfiguration schemes designed for MANETs. In addition, we look at a specific Stateless Autoconfiguration scheme (by Jelger and Noel, SECON 2005). This scheme provides globally routable IPv6 prefixes to a MANET, attached to the Internet via gateways. We examine this approach through OPNET simulation, applying new mobility models to encourage squad-like clusters around gateways, introducing mobility to the gateways, and scaling the number of ad hoc nodes and the number of gateways independently. We then comment on the performance of the Jelger-Noel addressing scheme in terms of protocol overhead, Autoconfiguration time, prefix hold times, and prefix stability.

  • Neighbor discovery and Stateless Autoconfiguration in IPv6
    IEEE Internet Computing, 1999
    Co-Authors: Thomas Narten
    Abstract:

    The next-generation Internet Protocol, IPv6, includes Autoconfiguration facilities that allow IPv6 hosts to plug into the network and start communicating with no special configuration required. These facilities address the requirements of hosts connecting to isolated standalone networks (such as home networks). The paper considers how the neighbor discovery protocols provide address-resolution services and allow hosts to find and keep track of routers, determine when a neighbor becomes unreachable, and switch dynamically to backup routers should the ones they are using fail
