Multiple Sink Based Compressive Data Aggregation Technique for Wireless Sensor Network

In a wireless sensor network, the single sink based data aggregation technique leads to inefficiency due to imbalance in energy consumption. Moreover it induces scalability problems and overload at the sink, since it is a "Many to one" pattern. Hence, in this paper, the authors develop a multiple sink based data aggregation technique, assuming the sinks are static. In this technique, initially a sink oriented tree is determined for each sink. If the amount of data in the network becomes large, the data is transmitted in the slots allocated for the specific part of the data such that interference is avoided in the data transmission.
