Most of the existing packet scheduling mechanisms of the wireless sensor network use First Come First Served (FCFS) non preemptive priority and preemptive priority scheduling algorithms. The above algorithms have high processing overhead and also long end-to-end data transmission delay. In FCFS concept the data packet which is entering the node first will go out first from the node, and the packet which will enter last will leave at last. But in FCFS scheduling of real time data packets coming to the node have to wait for a long time period.
