Abstract

One of the most important functions in the OLSR(optimized link state routing) protocol is the selection of multipoint relays(MPR) nodes. The routing calculations in this protocol rely on MPR to select related entries. The traditional MPR algorithm only reduces the flooding of the same message in the same area, and does not consider the time for newly added nodes in the network to obtain the topology information of the entire network. This paper studied this problem and proposed an efficient MPR selection algorithm. The algorithm had three steps: firstly, it reduced the problem of partial topology control(TC) message redundancy. And then it considered the effective coverage area when selecting MPR so that newly added nodes could obtain the entire network. It shortened the time required for topology information. Finally, considering the impact of mobility on the network topology, it estimated the location of the node at the next moment based on historical information, thereby enhancing the stability of the link. Through simulation, comparing the improved MPR algorithm with the traditional MPR algorithm, the end-to-end delay is reduced, and the success rate of data packet delivery is also improved.
