An optimized link state routing protocol based on a cross layer design for wireless mesh network

Abstract
Analysis of routing in Mesh Network reveals that Proactive routes are fast but suffers vulnerability of route failure under high mobility. Reactive routes on the other hand add extra overhead in the network for obtaining a route before every communication session. As Link state routing provides a Network Map at each node, It is well suited for a mesh network. However due to uncertain demand in the mesh network, link states needs frequent updation and refreshing. A refreshing phase halts current session thus adding latency to the session. In order to avoid this pitfall we propose a unique Cross layer Based Link State Routing for Mesh network. Nodes keep monitoring the link quality as an when a packet is received in a link. Signal to Noise Ratio and Received power is measured at the MAC layer. Any change in the stored value raises an event which is read directly by the network layer. Once Network layer gets the notification, it automatically updates the route table entry with new metric values. Thus there is no specific refresh phase and nodes automatically update the links and route cache. Once a node realizes that the link quality with its next hop has degraded and a better one is available, it opts a handover of the connection called vertical handover. Thus proposed system provides seamless connectivity under varying load and mobility.
