文摘

A fuzzy based routing technique is proposed to enhance the lifetime of randomly deployed homogenous sensor network for query driven applications. Multiple broadcast query from sink to the sensor nodes considers the routing uncertainties due to link quality, remaining energy and traffic load. Routing individual unicast replies from the sensor nodes to the sink will consider only link quality and remaining energy of each node. In the link layer asynchronous scheduling algorithm is used to reduce latency due to time synchronization for network communication. Nearest neighbor tree, Fuzzy and A star algorithms are used to find optimal route in the sensor network under energy and bandwidth constraints.
