Study of Energy Efficient Resource Allocation Algorithms for Wireless Sensor Networks
The Wireless Sensor Network (WSN) has got much importance these days. With the tracking and monitoring activities become essential, the deployment of sensor networks through wireless medium have also increased. Although sensors are unavoidable in many fields, they got many issues pertaining to energy, routing, security, coverage, delay, architecture etc.; There are many on-going researches in the field of WSNs. The enhancement of lifetime of sensors has become an important area of research. The fact that a sensor being a micro electronic device, equipped with limited power source. The power source supplies energy needed by the device for processing. If the nodes are deployed far apart, recharging and replacing are tedious process. Apart from hardware issues, the utilization of energy also plays a vital role. The energy go waste in many cases that includes, idle listening, retransmitting, overhearing, over-emitting. This research work reviews the different localization and resource allocation techniques basic and improved its nodes energy consumption in WSN and also presents some parameter based comparative study. This study is valuable for better understanding of existing methods and improved ones, with the help of this can develop other advanced techniques.
