OLSR (Optimized Link State Routing Protocol) is a routing protocol designed especially for MANETs (Mobile Ad-hoc NETworks) and is currently the most widely deployed for this type of networks. OLSR uses multipoint relay (MPR: Multi-Point Relay) flooding mechanism to optimize topology control messages broadcasting throughout the network. Each node of the network selects a subset of nodes (MPR) among its neighbors to disseminate control messages. Reducing Topology Control packets (TC) is the key functionality of OLSR. In the ad-hoc network, the number of TC depends on the choice of MPR.
