The widespread of mobile devices, such as Wi-Fi enabled laptops, PDAs and smart phones, makes mobile ad hoc networks (MANET) an attractive and low-cost alternative to create extended network service areas for users on the move. Unfortunately, the establishment of reliable multi-hop routes with mobile nodes that forward packets is a difficult task because of the temporal availability of links. In this paper, we revisit and evaluate the link durability routing protocol (LDRP), a low-overhead MANET protocol that can make use of node localization to improve the reliability of routes. We evaluate the protocol on a hybrid MANET/sensor network system where sensors provide tracking services to mobiles and the information needed by LDRP to achieve improved routing. In particular, we investigate the level of MANET reliability that can be achieved with sensor networks offering different levels of localization accuracy by altering network parameters, such as sensor density and communication patterns. A simulation study quantifies the benefits of the approach over AODV. Copyright © 2009 ACM.
