ALS: Aggregated Location Service for Routing in MANETs

One of the biggest challenges in MANETs is the design of scalable routing protocols. With the development and application of position devices, location-based routing has received growing attention. An important component of these protocols is the management of the location information at network nodes, this work is done by location services. In this paper, we present one such scheme called Aggregated Location Service (AILS) which scales well in large mobile ad-hoc networks. Simulation results show that under a specific environment the overhead cost of AILS is asymptotically lower than common methods that had been proposed for MANETs, while its reliability is reasonable.
