Improvement and Simulation Analysis of SMR Routing Protocol

Split Multipath Routing(SMR) protocol can not transmit split data efficiently and the condition of route discovery during route maintenance process is unreasonable in Ad Hoc network.To solve the problem,this paper proposes a new routing protocol P-SMR,the protocol uses delay as influence factor of the data allocation methods to improve transmission efficiency,and takes the number of broken paths and survival time of paths as conditions to find route.Simulation result show that compared with SMR and DSR protocol,average end-to-end delay and route cost decrease,and packet delivery fraction improves.
