Anti-Interference Based Multipath Link State Routing Algorithm for Ad hoc Networks

On the basis of the analysis to current multipath routing algorithm, a multipath routing algorithm modified from OSPF-MDR was designed. A node-disjoint path was realized by designing different processing strategies to source node, media node and destination node. The goal of balancing network overhead was also achieved by designing a new traffic splitting method based on anti-interference. Simulations show that the new algorithm can overcome the problem in realizing a link state multipath routing algorithm, decrease packets' average delay, increase packets' successful delivery ratio and improve the performance of the entire network further.
