In this research paper, an Energy Efficient QoS Routing Protocol for a WSN, i.e. QEERP has been proposed to reduce the energy consumption and increase the overall life-time of the networks. On evaluating the performance of the proposed algorithm QEERP, the participating normal node performs in terms of energy consumption 18%, 15% and 14% better with respect to LEACH and 12%, 9% and 7% better with respect to SEPE and further, on evaluating the performance of the advance nodes in terms of overall energy consumption, the energy consumption is reduced gradually and conserve 7% and 10% at 0.2 and 0.3 probabilities with respect to LEACH, however, adversely affected at 0.1 probabilities to be the CHs in a particular round. On evaluating the performance for all nodes, It shows that the average energy of all nodes conserve by 7% and 10% energy at 0.2 and 0.3 respectively but at the same time the proposed algorithm adversely affected by 0.7% with respect to LEACH because of less number of CHs are available to process the data that is received from the participating sensor nodes and to forward the same to the sink node. The proposed algorithm gradually improves the average energy conservation of all participating sensor nodes on increasing the probability with respect to SEPE. It is also being observed that the proposed algorithm performing well when number of clusters and CHs are more in numbers.

Keywords: The wireless sensor network (WSN) is a collection of micro-sensors used to sense, collect, process, and transmit the data to the cluster heads (CHs). Further, the cluster heads are responsible to send the accumulated data to the sink node(s) to collect
