Paper Details

The paper deals with hybrid wireless sensor network where both static and mobile sensors are used, where staticsensors detects one attributes or one event like location of the device where as the mobile sensors detects multiple attributeswhich is more in-depth analysis, critical issue is setting the path for this mobile sensors. Recent advances in wireless sensornetworks have led to many new protocols specifically designed for sensor networks where energy awareness is an essentialconsideration. Most of the attention, however, has been given to the routing protocols since they might differ depending onthe application and network architecture. However, in cognitive radio (CR) ad hoc networks, unlicensed users may observeheterogeneous spectrum availability, which is unknown to other unlicensed users before the control information wasbroadcast. Transmission of video and imaging data requires both energy and QoS aware routing in order to ensure efficientusage of the sensors and effective access to the gathered measurements. In this paper, we propose an energy-aware QoSrouting protocol for sensor networks which can also run efficiently with best-effort traffic. Moreover, the throughput for nonreal-time data is maximized by adjusting the service rate for both real-time and non-real-time data at the sensor nodes.Simulation results have demonstrated the effectiveness of our approach for different metrics.
