A Survey on Data Routing and Aggregation Techniques for Wireless Sensor Networks

Sensor nodes are operating at low voltage and working on battery supply. The main challenge while designing the Wireless Sensor Network is to reduce energy utilization and construct effective route strategy to increase lifetime and relia-bility of the network. For various applications, Wireless Sensor Networks (WSNs) are getting deployed frequently, continuously and they are increasing day by day. Because of high density of WSN nodes there is high probability that redundant data will be sensed by surrounding nodes. Energy conservation is most affecting factor in building a network. It is not suitable to send data individually or separately by each node. Thus the data aggregation is desired in which certain node collects the data and then finally forwards towards destination node. Using this aggregation technique we can save cost and energy consumption in networking. Data routing in network aggregation is also called as DRINA. It provides a better solution like reduced number of message in routing tree, secure data aggregation, high aggregation rate, reliable, and transmission in wireless sensor network. In this survey, we highlights various approaches and algorithms for data routing and aggregation.
