The Effect of GPS Error on MLAR1

摘要

The Mobile Ad hoc Network (MANET) has become an increasingly popular area of research during the last decade. As an emerging fourth generation wireless topology, the main goal of the MANET will be to seamlessly connect mobile devices anywhere and anytime. Recently, the introduction of Ultra-WideBand (UWB) technology has become a promising candidate to support MANET's and research in this area has been extensive over the last few years due to its powerful capabilities such as the large Band Width (BW) available and the high data rates possible. Routing protocols enable mobile hosts (or nodes), such as laptops and cellular telephones, the ability to communicate with each other and the design of routing protocols has encouraged researchers to investigate and develop new strategies that establish and maintain connections between mobile nodes. The main aim of the research presented in this paper was to reduce the effect of GPS error in determining nodes' positions on the performance of Modified Location Aided Routing Protocol (MLAR1). Simulation results along with the analytical model show that the MLAR1 reduce the effect of GPS error on the performance in terms of consumed energy, throughput, routing overhead, reliability of route, and the average end-to-end delay.
