The OLSR(Optimized Link State Routing Protocol RFC3626)is a pre-active table driven routing pro- tocol applied in Ad hoc networks.Through analysis,the shortcoming of MPR selecting that it may results in so many redundant nodes possibly in MPR set is revealed.Then an improved OLSR,which deletes the redundant nodes in MPR set by sorting and judging again,is presented.Simulation results show that the improved OLSR has good per- formances on the number of sending TC packets,received TC packets' number by all nodes and average end-to- end delay.So the improved OLSR reduces the TC packets' flooding,and improves the networks' performance.
