Abstract

Energy conservation in sensor networks has become a major research issue over the years. For sensor nodes, most of its energy is consumed for communicating the data across the network. Hence, with controlled communication, energy spent can be minimized by transmitting only required and critical information. This work is a step towards developing an energy efficient sensor network through the development of energy aware application layer. Our work draws from the fact that, in sensor applications reporting all the detected information will result in communication of redundant information leading to unnecessary energy consumption. In this work we restrict the sensor nodes to transmit only when a change is detected. The idea behind this work is two-fold; first the information detected by the sensor nodes is monitored; secondly, if the information does not change over a period of time, then the updates are not reported. The data is forwarded only when a change is observed in the detected information. The adaptive data forwarding approaches reduce redundant data transmissions thereby minimizing energy consumption. The algorithms were implemented and the simulations were run using NS 2.26. The results suggested an improvement of up to 40% in energy efficiency.
