Transmission of video and imaging data requires both energy and QoS aware routing in order to ensure efficient usage of the sensors and effective access to the gathered information. In large-scale networks with a large number of sensor nodes, multiple sink nodes should be deployed to increase the manageability of the network and also to reduce the energy dissipation at each node. In this paper we propose a multi-sink wireless sensor network architecture where the network is partitioned into clusters with multiple sinks. All the sources in a cluster were assigned to send the data to the sink designated to that particular cluster. The proposed CBEEQR protocol ensures end-to-end delay requirement of real time data, as well as maximizes the throughput of non real-time data by transmitting the gathered data to the appropriate sink. Simulation results have demonstrated the effectiveness of our approach for different metrics.
