Research for Source Routing Based Multipath Routing Protocol

摘要

OLSR (Optimized Link State Routing) is a table-driven protocol for Mobile Ad hoc Networks (MANET), which has wide potentials in military applications. In this paper, a Source Routing based Multi-Path OLSR (SR-MPOLSR) protocol is proposed in this paper. With this protocol, MPRs (Multi-Point Relay) are used to obtain the network topology effectively and multiple Dijkstra algorithms are used to calculate multiple routes and to allocate the loads in a weighted round-robin fashion. Data transmission at the source is carried out through predetermined multiple paths (hence source routing). Our experiments have shown that SR-MPOLSR can, to some extent, increase the utility of network resources and network throughput, improve robustness and reliability of the transmission service, and reduce the average transit delay.
