An Energy Efficient Multilevel Priority Packet scheduling scheme for WSN

Abstract

Wireless sensor network(WSN) consist of compact distributed self-organizing wireless nodes with small amount of CPU memory, low processing power and low battery capacity. The wireless nodes generates different types of data packets such as real time and non-real time data packets because it sense environmental situations. WSN uses most existing packets scheduling system i.e. First come first serve(FCFS).In FCFS concept the data packets which enter the node first will leave the node first. In this process there might be starvation of real time data packets because data packets are processed according to the time but they are not processed according to priority. Scheduling different type of package in WSN is highly important since it ensure deliver of different type of packets based on their priority and fairness with minimum latency.
