基于联合感知模型的无线传感器网络连通性覆盖协议
Connected Coverage Protocol Using Cooperative Sensing Model for Wireless Sensor Networks
摘要
Abstract
This paper focuses on the quality of coverage (QoC) and connectivity problems for wireless sensor networks, considering the cooperative sensing model and the multi-adjustable communication rang without location information. For the random deployment policy, the performances of the network QoC and the network connectivity for various number of active nodes, different area of the monitored region and changeable performance parameter of each node are presented respectively. Furthermore, the scheduling control algorithm (SCA) is designed to guarantee the QoC and connectivity of networks with the least number of nodes.It chooses the uniformly-located working nodes and makes sure that the energy consumption of each node consumes homogeneously. Simulation results show that the active node number employed in the cooperative sensing model to provide the desired QoC of networks is less than that of the binary sensing model. And the SCA policy not only provides the desired QoC and connectivity of networks,but also reduces the total energy consumption and balances the energy dissipation among nodes.关键词
