Improving MPR Selection Algorithm in OLSR Protocol Based on Node Localization Technology

The MPR technology in the OLSR routing protocol is described, it is pointed out that there are some limitations when the default heuristic algorithm in this protocol is used to find the minimum MPR. In this paper, an improved algorithm based on node localization is proposed combined with node localization technology. Node localization information is used in this algorithm, the blindness is reduced in the MPR selection algorithm in the OLSR protocol, it can make full use of the network resources, the number of routing packets needed to deliver in the network is reduced to a certain extent, and therefore it can improve the network transmission capacity. The improved algorithm is implemented in network simulation environment, the results are analyzed, it shows that the proposed improved algorithm is feasible and applicable, and the location-based heuristic selection strategy is appropriate and correct.
