A NEW APPROACH TO SECURE DATA AGGREGATION IN WIRELESS SENSOR NETWORKS

Abstract

However, primarily due to the severe constraints and secondarily due to the inherent increased costs in communications relative to that in processing, the WSNs follow in-network processing, wherein the emphasis is on on-thefly processing of the data packets before being communicated eventually to the base station [3]. The processing typically consists of the data aggregation operations like summarization, summation, averaging, finding the minimum/maximum of a set of sensed values. The eventual advantage of data aggregation is the overall reduction on the total number of packets transmitted to the base station resulting in conservation of energy and bandwidth. 2.
