Load based energy aware multimedia routing protocol-(LEAR)

The growing popularity of wireless sensor networks (WSNs) lead to the shifting of research focus from WSNs to wireless multimedia sensor networks (WMSNs). Most existing routing protocols for WSNs do not satisfy the need of continuous and higher data rate routing requirements of WMSNs. In this paper a new routing protocol (LEAR) for WMSNs has been proposed which establish routing paths based on node energy and routing load of a node. LEAR aims to find completely or partially disjoint paths for routing multimedia traffic. Simulation results have shown that for source nodes which are very close together LEAR is capable of finding different disjoint or partial disjoint paths.
