Taking Binary Error Rate into Account to Improve OLSR Protocol

Abstract : This paper presents BER-OLSR, an enhanced OLSR protocol. We modify OLSR standard route choice and Multi-Point Relays (MPR) selection processes. Particularly, our new protocol takes into account Bit Error Rate (BER) of links during MPR selection and routing table calculation. MPR set of a node is populated so that access to each 2-hop-neighbor is ensured by the best path in terms of BER. For routing table calculation, lowest BER is privileged over lowest number of hops. Performances of this protocol are evaluated by simulation with realistic propagation and mobility models. We show that this new approach of OLSR routing protocol provides better packet delivery ratio and delay than the original OLSR algorithm, even in unfavorable conditions such as mobility or several interfering communications.
