Publication Detail
Adaptive routing for intermittently connected mobile ad hoc networks
Abstract
The vast majority of mobile ad hoc networking researchmakes a very large assumption: that communication canonly take place between nodes that are simultaneously accessiblewithin in the same connected cloud (i.e., that communicationis synchronous). In reality, this assumption islikely to be a poor one, particularly for sparsely or irregularlypopulated environments.In this paper, we present the Context-Aware Routing(CAR) algorithm. CAR is a novel approach to the provisionof asynchronous communication in partially-connected mobilead hoc networks, based on the intelligent placement ofmessages. We discuss the details of the algorithm, and thenpresent simulation results demonstrating that it is possiblefor nodes to exploit context information in making local decisionsthat lead to good delivery ratios and latencies withsmall overheads.
