Path selection algorithms for fault tolerance in wireless mesh networks. Telecommunication systems, 2012
abstract
Recently Wireless Mesh Networks (WMNs) have emerged as a key technology for providing high-bandwidth networking among peer nodes over a specific coverage area. Features such as low cost, ease of deployment, self-configuration and self-healing make them one of the most promising global telecommunication systems. Despite their advantages, however, several research challenges remain in all protocol layers. In this paper, we address the main challenging issues related to the routing aspects in a WMN. Routing in such networks is performed through multi-hop paths where intermediate nodes cooperatively make forwarding decisions based on their knowledge regarding the network topology. However, in an unideal dynamic environment due to frequent or rare node failures/misbehavior, traditional ad-hoc routing protocols suffer from high routing overhead or energy consumption. Motivated by this, we propose several path selection algorithms which adapt to such topology dynamics. The main objective of these routing schemes is to provide fault tolerance without sacrificing the energy and computational complexity efficiency. Numerical investigations, based on extensive simulations, validate the effectiveness of our proposals even when faulty nodes subsist in the environment.

A prediction based mobility extension for eHIP protocol. ISCIS '11 : 26th International Symposium on Computer and Information Sciences, London;Dordrecht;Heidelberg : Springer, 26-28 september 2011, London, United Kingdom, 2012, pp. 209-213, ISBN 978-1-4471-2154-1
abstract
By revealing of heterogeneous networks, importance of cooperation of different technologies and mobility management became an important issue of wireless and mobile networks. The idea of separation the role of IP addresses for location and identification of a mobile node in the network has also increased its importance. In this study, our motivation is to extend our previously proposed handover management method (early update for host identity protocol (eHIP). We propose to introduce the idea of simply employing movement prediction idea to regular eHIP and so enhancing the handover latency.
