Improvement of Multipath Routing Algorithm Based on OLSR and Source Routing
Hong Zhang · Journal of Southwest Jiaotong University · 2010
The OLSR(optimized link state routing) and source routing-based multipath algorithm(SR-MPOLSR) was simulated.The simulation results indicate that the SR-MPOLSR has disadvantages in finding a source routing path and can not improve the success rate of end-to-end packet transmission because of uncompleted topology information and multipath coupling problem.In order to get the complete structure of network topology,redundant diffusion,agent announcement and agent selection were extended on OLSR.A multipath selection algorithm with a coupling factor 0 was proposed to avoid interferences among multipath flows from a same source.The research results show that the end-to-end packet success rate of the improved algorithm is approximately 10% higher than that of the SR-MPOLSR in heavy network load conditions.
