In this paper we present a novel TDMA-based medium access control (MAC) protocol for wireless sensor networks. Unlike conventional MAC protocols which function independently of the application, we introduce an Adaptive, Information-centric and Lightweight MAC(AI-LMAC) protocol that adapts its operation depending on the requirements of the application. We also present a completely localised data management framework that helps capture information about traf?c patterns in the network. This information is subsequently used by AI-LMAC to modify its operation accordingly. The data management framework can additionally be used for ef?cient query dissemination and query optimisation. We present preliminary results showing how the MAC protocol ef?ciently manages the issues of fairness and latency.
