Energy Efficient Clustering and Grid Based Routing in Wireless Sensor Networks

A wireless sensor network is a deployment of massive numbers of small, inexpensive, self powered devices that can sense, compute and communicate with other devices for the purpose of gathering local information to make global decisions about a physical environment. Wireless Sensor Networks are tightly constrained in terms of transmission power, onboard energy, processing capacity and storage, and thus require careful resource management. We mainly have LEACH(Low Energy Adaptive Clustering Hierarchy) and PEGASIS(Power Efficient Gathering in Sensor Information Systems) protocols. But LEACH doesn't support distribution of cluster heads optimally and PEGASIS has the overhead of data delay. This proposed approach emphasizes on increasing network lifetime via efficient routing path ands, efficient energy consumption.
