Networking hundreds or thousands of cheap microsensor nodes allows users to accurately monitor a remote environment by intelligently combining data from individual nodes. These networks require robust wireless communication protocols that are energy efficient and provide low latency. We develop and analyze the energy-efficient Adaptive Clustering Hierarchy (LEACH), a protocol architecture for microsensor networks that combines cluster-based and energy-efficient media access ideas in conjunction with application-specific data aggregation to achieve a good performance in terms of system life, latency and quality perceived by the applications. LEACH includes a new distributed clustering technique that allows the self-organization of a large number of nodes, algorithms for adapting clusters and positions of rotating group heads to evenly distribute the energy load between all nodes and techniques to allow the processing of distributed signals to save communication resources.
