A Survey on Routing Techniques for Correlated Data in Wireless Sensor Networks
نویسندگان
چکیده
Wireless Sensor Networks require several sensing nodes in the network to transfer the sensed data to the base station so that it provides up-to-date information on the event. A routing protocol is often triggered in order to find a path to the sink so that the nodes can report the event to the sink. The principal task of a routing algorithm is to determine which set of intermediate nodes is to be selected to form an efficient data forwarding path between source and the destination. The Sensor data from different nodes in a dense region may be highly correlated. Correlated data when routed across a wireless sensor network leads to the duplication of data at various nodes, thereby consuming a vast amount of energy. This paper conducts a survey on the various techniques that provide an energy efficient routing for correlated data in wireless sensor networks. KeywordsMultihop, Correlation, query, Maximum Lifetime, routing algorithm
