Optimal Packet Scheduling Using Energy Harvesting For Wireless Sensor Network

Real time and non-real-time data packets are the two types of scheduling packets which is used at sensor nodes with resource constraints in WSN of importance to reduce sensors energy and end-to-end delays. Existing First Come First Served, starvation of high priority real-time data packets due to the transmission of a large data packet in nonpreemptive priority scheduling, starvation of nonreal-time data packets due to the probable continuous arrival of real-time data in preemptive priority scheduling, and improper allocation of data packets to queues in multilevel queue algorithms . A Dynamic Multilevel Priority has priority queues in the zone-based topology , except the last level. Realtime packets are placed high priority queue and nonreal-time packets are placed into two other queues based on a certain threshold , leaf nodes are realtime and non-real-time data packets since they do not receive data from other nodes and thus, reduce endto-end delay.
