An Optimal Scheduling Scheme for Wireless Sensor Network

In Wireless Sensor Network (WSN) is an emerging technology for data transfer through a number of sensor nodes. The main cause of wasted energy consumption is packet collision. The sensor nodes are powered by batteries with limited energy. Packet scheduling is the process of resolving contention for shared resources in a network. Scheduling algorithms for every network need to be selected based on the type of users in the network and their QoS requirements. Due to transferring the data packet collision may occur so we are using scheduling algorithm. The project proposes Earliest Dead-line First (EDF) scheduling algorithm for scheduling the data packets in the queue for each node. The proposed scheduling algorithm is used for queue based scheduling because of which we can reduce the energy, transmission delay and packet loss. The queue is filled with earliest sending packets consist of lower size inside the queue so that the traffic can be reduced, the node energy can be maintained and delay of the packet cannot occur.
