Efficient Wireless Charger Deployment for Wireless Rechargeable Sensor Networks
A wireless rechargeable sensor network (WRSN) consists of sensor nodes that can harvest energy emitted from wireless chargers for refilling their batteries so that the WRSN can operate sustainably. This paper assumes wireless chargers are equipped with directional antennas, and are deployed on grid points of a fixed height to propose two heuristic algorithms solving the following wireless charg...
متن کاملA Power Balance Aware Wireless Charger Deployment Method for Complete Coverage in Wireless Rechargeable Sensor Networks
Traditional sensor nodes are usually battery powered, and the limited battery power constrains the overall lifespan of the sensors. Recently, wireless power transmission technology has been applied in wireless sensor networks (WSNs) to transmit wireless power from the chargers to the sensor nodes and solve the limited battery power problem. The combination of wireless sensors and wireless charg...
متن کاملAn Adaptive Algorithm for Charger Deployment Optimization in Wireless Rechargeable Sensor Networks
Wireless chargers are used to refill sensors’ power supply in a wireless rechargeable sensor network (WRSN) so that the WRSN can operate sustainably. Since wireless chargers are costly, the problem about how to deploy as few as possible chargers to make a WRSN sustainable is important. This paper proposes a greedy algorithm, named adaptive pair based greedy cone selection (APB-GCS), to consider...
متن کاملan efficient protocol for data aggregation in wireless sensor networks
sensor networks generally consist of a very great number of sensor nodes which will be spread into a vast environment and aggregate data out of it. the sensor nodes are afflicted with some limitations as follows memory, reception, communication as well as calculation capability, and battery power. the transmission of a great amount of extra data increases data transmission and proportionally in...
متن کاملQuasi Random Deployment Strategy for Reliable Communication Backbones in Wireless Sensor Networks
Topology construction and topology maintenance are significant sub-problems of topology control. Spanning tree based algorithms for topology control are basically transmission range based type construction algorithms. The construction of an effective backbone, however, is indirectly related to the placement of nodes. Also, the dependence of network reliability on the communication path undertak...
