As a mobile wireless network, Ad Hoc network has the characteristic of flexible network structure. Optimized Link State Routing (OLSR) protocalis a standard apriori routing protocol designed to meet the requirements of wireless Ad Hoc network and optimize pure link-state algorithms. A distributed multi-hop Ad Hoc networking technology based on OLSR protocol is designed to solve the need of multi-hop addressing due to the change of network topology. The technology takes into account the connectivity and forwarding intention of the network members through distributed network perception, as well as selects the relay nodes in the network according to the distributed adaptive Multi-Point Relay (MPR) set selection algorithm, which provides the multi-hop addressing capability for users. The feasibility of the technology is verified by the OMNET++ simulation platform.
