A Survey on Data Approximation Techniques for Wireless Sensor Networks

Abstract

Wireless sensor networks are very useful in a variability of locales. A main contest in these networks is to minimize energy consumption. By minimizing energy consumption we can increase the lifetime of wireless sensor networks. The recent studies on wireless sensor networks shows that by applying data approximation techniques we can significantly improve the lifetime of wireless sensor network. In this backdrop this paper formalizes various data approximation techniques that can be applied to wireless sensor networks. By applying these data approximation techniques we can significantly reduce the number of messages transmitted. Thereby communication overhead will be reduced. Reducing communication automatically increases the lifetime of wireless sensor networks.
