Distributed Location Service with Spatial Awareness for Mobile Ad Hoc Networks

A mobile ad hoc network (MANET) consists of a collection of wireless mobile nodes without any fixed network infrastructure Since the mobile nodes form a constantly changing topology the design of efficient and scalable routing protocols is a fundamental challenge in MANETs In the current literature position based routing pro tocols are regarded as having better scalability and lower control overhead than topology based routing protocols Since location services are the most critical part of position based routing protocols we present a multi home region scheme Distributed Virtual Holm Region with Spatial Awareness (DVHR SA) to improve the performance of location service in this paper Our scheme adaptively selects different update and query procedures according to the location of a source node The simulation results show that DVHR SA shortens the lengths of the update query and reply paths Our scheme also reduces the overall network message overhead Therefore DVHR SA is considerably fast and stable
