Context-aware Adaptive Routing (CAR) Protocol A Protocol for Delay Tolerant Mobile Ad Hoc Networks The vast majority of mobile ad hoc networking research makes a very large assumption: that communication can only take place between nodes that are simultaneously accessible within in the same connected cloud (i.e., that communication is synchronous). In reality, this assumption is likely to be a poor one, particularly for sparsely or irregularly populated environments. Moreover, asynchronous communication such as email, which is by far the pre-eminent form of networked person-to-person communication, has a natural fit to such partially-connected environments, but has been relatively little explored in the context of mobile ad-hoc networking. This is perhaps unsurprising, given the complexities involved. Indeed, the few approaches that have been described to date are simplistic or heavyweight, relying on brute force methods in order to achieve message delivery. The Context-Aware Routing (CAR) algorithm is a novel approach to the provision of asynchronous communication in delay tolerant networks, based on the intelligent placement of messages. CAR has been implemented for the Haggle platform; the code will be released soon.
