Design and Implementation of Context-Aware Adaptive Routing for Delay-Tolerant Mobile Networks

Abstract

Mobile ad hoc network research has often assumed that a connected path exists between a sender and a receiver node at any point in time. This assumption reveals itself unrealistic in many decentralized mobile network applications such as vehicular networks, wildlife monitoring sensor networks, deep space communication systems and emergency operations networks. To response this dichotomy, delay tolerant networking (DTN) has established considerable attention from the research community in current years as a means of addressing precisely the issue of routing messages in partitioned networks. In this paper, we present the design, implementation of the context-aware adaptive routing (CAR) protocol for delay-tolerant unicast communication in intermittently connected mobile networks. The protocol is based on the idea of exploiting nodes as carriers of messages among network partitions for message delivery.
