ABSTRACT

Geographic addresses are essential in position-based routing algorithms in mobile ad hoc networks, i.e. a node that intends to send a packet to some target node, has to know the target's current position. A distributed location service is required to provide each node's position to the other network nodes. Grid Location Service (GLS) has been known as a promising location service approach. In this paper we present a new approach called TGrid and describe the performance of a novel multi-level Tree-walk grid location management protocol for large scale ad hoc networks. We provide a qualitative comparison of GLS and TGrid using statistical analysis beyond the results of the original paper and a theoretical framework. We present analytical results with respect to three main metrics: query cost, maintenance cost, and storage cost under two traffic patterns: uniform and localized traffic pattern. The proposed approach is evaluated through mathematical analysis, and the results indicate that our protocol scales 11well with increasing of node-count, node-density and node-speed. We show that the tree Main metrics, query cost, maintenance cost, and storage cost in TGRID grows only logarithmically in the total number of nodes in a uniformly randomly distributed network.
