Routing is an important issue in sensor network for ensuring Quality of Service (QoS). It is very challenge task for ensuring QoS in monitoring and surveillance system because these applications require delayless and reliable data delivery service. Existing work uses multipath routing approach which consumes more energy. In this work we used Geographic Opportunistic Routing for providing Quality of Service in Wireless Sensor Network and also this protocol cannot be directly applied to guarantee both reliability and delay constraints in on efficient manner. In order to provide efficient Quality of service, we used candidate selection and prioritization algorithm in Efficient QoS Aware GOR (EQGOR). This algorithm ensures energy efficiency, end to end reliability and time complexity. The implementation shows graph of improved throughput and Packet Delivery ratio using this algorithm in NS2.
