Abstract
Wireless Mesh Networks (WMNs) are the hybrid networks having fixed infrastructure of gateways to provide the Internet connectivity to its fixed or mobile clients. It has redundant links to provide reliable communication. Anycast is an important service for the group communication. Field based routing is getting popularity due to its robustness and simplicity. In this paper, we have studies on the security issues for the anycast service based upon the field based routing. The scheme has been studied to eliminate the effects of the external intruders and also against the internal selfish nodes. The modified secure field based routing strategies have been proposed to safeguard the legitimate traffic from these external and internal intruders. The simulation results in OMNet++ simulator shows that the proposed techniques outperform the normal routing mechanisms. Key words: Anycast, field base routing, security.
Highlights
Wireless Mesh Networks (WMN) is a multi-hop wireless networks like MANETs, the change in structure and behavior of mesh network make the routing mechanism relatively different as compared to other networks (Akyildiz et al, 2005; Bruno et al, 2005)
Anycast is a service which can increase service availability. It is a special type of routing in which a packet transmits to any node among a group. This single destination node may be chosen by different types of parameters like number of hops, delay or other metrics
There are set of anycast destination nodes
Summary
Wireless Mesh Networks (WMN) is a multi-hop wireless networks like MANETs, the change in structure and behavior of mesh network make the routing mechanism relatively different as compared to other networks (Akyildiz et al, 2005; Bruno et al, 2005). Anycast is a service which can increase service availability It is a special type of routing in which a packet transmits to any node among a group. We have used the field based routing for the anycast routing in wireless mesh networks. Filed based routing is prone to various internal and external intruders’ attacks. As it depends solely on a routing filed; any intruder may mislead the nodes towards itself by introducing the maximum routing filed wrongly. Is why there is need to propose the security measures to secure the field based routing for anycast routing in wireless mesh networks
