Features of WSN and Data Aggregation Techniques in WSN: A Survey

Sensor networks consist of several sensor nodes which co-operatively send sensed data to base station. One of the critical constraints of sensor nodes is the power consumption requirement. Sensor nodes carry limited, generally irreplaceable, power sources. In real life scenario when these sensor nodes are deployed in any environment it is possible that these nodes may not be closely located to the base station in fact the nodes themselves may be far off distance from each other. As sensor nodes are battery driven, an efficient utilization of power is essential to reduce data traffic inside sensor networks thus reduce amount of data that need to send to base station thereby enhancing the network lifetime.
