Abstract:
Proactive link state routing protocols, as used within the Mobile Ad hoc NETwork framework, have not been as successful in wireless sensor networks. This is mainly due to the extensive energy usage by control traffic transmissions and state requirements. However, such protocols are in many situations a more suitable candidate than their counterparts. The benefits are their topology overview, and more importantly the already available spanning trees for information distribution. The high signaling overhead associated with proactive protocols can be reduced by taking advantage of the static nature of wireless sensor networks. In this paper, we investigate how the Optimized Link-State Routing (OLSR) protocol, as a proactive routing protocol candidate, can be adapted to work better in a wireless sensor network environment. The basis for the solution is that control messages are sent with a low frequency when the network is stable, and more often if topology changes occur. The proposed solution is investigated using simulations from no loss to lossy link environments showing promising results.
