Long-lived path routing with received signal strength for ad hoc networks

Routing paths in mobile ad hoc networks are easily disrupted due to the mobility of nodes. Therefore, it is desirable to find a routing path such that all edges in the path are long-lived. Based on the ad hoc on-demand distance vector routing (AODV) protocol, we propose an AODV-RSS (AODV with received signal strength) routing protocol such that connectivities of links in the route found can sustain longer. The AODV-RSS algorithm uses the received signal strength, RSS9 and the received signal strength changing rate, ARSS, to predict the link available time, LAT. Using the LAT as a constraint, our method will find out a satisfying routing path. Simulation results show that our routing algorithm can greatly improve the quality of the routing path in route connection time, and route reestablishment frequency.
