RESA-OLSR: RESources-aware OLSR-based routing mechanism for mobile ad-hoc networks

This paper describes the performance enhancements of the routing mechanism for mobile ad-hoc networks. The presented solution is based on the proactive Optimized Link State Routing (OLSR) protocol. A new method was introduced to calculate the node performance metric with respect to the local resources, i.e., the battery level and the available bandwidth. This metric is reflected by the Willingness value disseminated by each node running OLSR and used to select Multi Point Relays (MPRs). Simulation results demonstrate that the advantages of the solution are better network reliability and increased lifetime.
