AI-LMAC: An Adaptive, Information-centric and Lightweight MAC Protocol for Wireless Sensor Networks

摘要

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.
