SFBR: A Secure Field Based Routing approach for wireless mesh network

Wireless mesh network is a new type of network paradigm in which each node communicates to others to enhance network reliability and performance. Routing in wireless mesh network is a challenging task. Despite from the traditional routing, field based routing uses a little information to route the packets. Due to this characteristic, field based routing algorithms are inexpensive and robust, but such algorithms are also prone to different security attacks. In this paper, a novel Secure Field Based Routing Algorithm (SFBR) is proposed which routes the packets securely from the Gateway to the Mesh nodes. SFBR has been extensively tested using Omnet++ network simulator for unicast, anycast and geocast type of traffic to identify and isolate the malicious node and to prevent the traffic flows from various active and passive attacks.
