A JOINT DUTY CYCLE SCHEDULING AND ENERGY AWARE ROUTING APPROACH BASED ON EVOLUTIONARY GAME FOR WIRELESS SENSOR NETWORKS
Network throughput and energy conservation are two conflicting important performance metrics for wireless sensor networks. Since these two objectives are in conflict with each other, it is difficult to achieve them simultaneously. In this paper, a joint duty cycle scheduling and energy aware routing approach is proposed based on evolutionary game theory which is called DREG. Making a trade-off ...

متن کاملASP: An Adaptive Energy-Efficient Polling Algorithm for Bluetooth Piconets
Among the various wireless technologies available today, Bluetooth stands out as the most promising for use in low-power sensor networks. This is especially true for large networks of sensors with low data rates, where Bluetooth’s low power Hold, Sniff, and Park modes could be utilized during periods of low activity to reduce power consumption. One way that these modes can be exploited to reduc...
متن کاملA Dichotomized Rendezvous Algorithm for Mesh Bluetooth Scatternets
A Bluetooth scatternet is formed by sharing some nodes (bridges) among piconets in a time division multiplex basis. Effective coordination of these bridge nodes is crucial for the smooth operation of a scatternet. In this paper, a distributed, two-phase RP scheduling algorithm called Dichotomized Rendezvous Point algorithm (DRP) is presented to address this problem. DRP makes the assumption tha...
