Node Discovery Algorithm Based Multipath OLSR Routing Protocol

Multipath routing which has great potential to improve network characteristics for mobile wireless networks is one of central problems nowadays. Since most of the proposed multipath algorithms are On-Demand based, they need extra feedback information that lead the delay to grow. In this paper, we propose a proactive Multipath Optimized Link State Routing Protocol (MOLSR) based on OLSR(Optimized Link State Routing Protocol), which introduces the cross-layer concept as well as the node discovery algorithm employed to discover every node on the route to build disjoint path. Simulation results show that MOLSR achieves lower delay and packet drop ratio with little more overhead than the classic OLSR algorithm.
