Long-lived Path Routing With Received Signal Strength for Ad Hoc Networks
Ruay-Shiung Chang, S.-J. Leu · 2006
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.
