In Wireless Sensor Networks (WSNs) scheduling different types of packets, such as real time and non-real-time data packets, WSN have limited energy resource constraints to reduce sensors energy consumptions. The offered packet-scheduling mechanisms of WSN use First Come First Served (FCFS), These algorithm obtain a high processing overhead and high end-to-end data transmission delay due to the FCFS concept, the high priority real-time data packets due to the transmission of a large data packet in non preemptive priority scheduling, the non-real-time data packets due to continuous arrival of real-time data in preemptive priority scheduling and improper allocation of data packets to queues in multilevel queue scheduling algorithms.
