GeoOLSR: Extension of OLSR to support Geocasting in Mobile Ad Hoc Networks

Keywords: Geocasting, OLSR, AODV, IEEE802.15.4, Ray Tracing

Abstract:
Safety critical applications of IEEE802.15.4 networks require autonomous network reconfiguration and dynamic meshing in case of node failures or changing environmental influences. This paper demonstrates the application of Ad hoc On Demand Distance Vector (AODV) and Optimized Link State Routing (OLSR) on IEEE802.15.4 nodes based on an IP layer. The modular concept leads to the proposed extension of Optimized Link State Routing (OLSR) protocol to provide location-based services and addressing inherently in the protocol design. We demonstrate the changes in message flows and information exchange that are necessary to develop a geo-implementation of OLSR, which we call GeoOLSR throughout this paper. For performance evaluation, we will first examine mobile ad hoc relevant metrics like time delay, maximum throughput and generated overhead. Furthermore, the lifetime of the novel node architecture is evaluated in comparison to the ordinary IEEE802.15.4 configuration and IEEE802.11. Finally, the real-world protocol behavior of GeoOLSR is shown for different mobility speeds by using realistic ray tracing for modeling the physical transmission in a harsh industrial environment. Thus, it is proven by results that GeoOLSR is able to support both IP enabled unicast traffic and geographical addressing even in resource constrained networks like IEEE802.15.4.
