Abstract—The most of the existing packet scheduling mechanism of Wireless Sensor Network (WSN) use First Come First Serve (FCFS), Earliest Deadline First (EDF), non-pre-emptive scheduling, pre-emptive scheduling, multi-level priority, Dynamic multi-level packet scheduling algorithm. The FCFS schedule algorithm process data packets in the order of their arrival time and thus require a lot of time to be delivered to base station. In this project Enhanced Dynamic Multilevel Priority (EDMP) Packet Scheduling Scheme is proposed.To develop a packet scheduling scheme for avoiding the occurrence of deadlock due to the real time tasks holding the resources for a longer period of time. By using circular wait and pre-emptive conditions. By using the proposed method throughput is increased and end-to-end delay is reduced

KeywordsWireless Sensor Network(WSN), pre-emptive priority scheduling, real-time, non-real-time,circular wait condition.
