Performance Evaluation of the Location-Based Protocol DREAM for Large Mobile Ad Hoc Networks

Abstract

Position-based routing protocols were recently proposed as a solution to non-scalable topology-based routing protocols for large scale mobile ad hoc networks. In these position-based routing protocols, nodes may not maintain explicit routes. Each node needs only to know its own position and the position of its one-hop neighbors to forward packets. In this paper, a performance evaluation of the position-based routing protocol DREAM for large scale ad hoc networks is presented. Several performance metrics such as the control load and the average latency are evaluated using ns2 for up to 500 nodes generated according to the realistic mobility model RealMobgen.
