面向动态传感器网络的数据汇集算法

Data Collection Algorithm for Dynamic Sensor Networks

传感器网络中移动终端广泛存在,针对无线传感器网络移动Sink场景,提出一种移动Sink代理机制和网络质量评估策略。根据网络质量决定S ink的移动路径,并在此基础上,从能量均衡的角度提出一种基于角度的数据汇集算法ADC-MS(Angle-based Data Collection algorithm for Mobile Sink),通过下一跳节点选择概率公式优化数据汇集路径。仿真表明,算法能有效均衡网络能耗、具有较高的可靠通信程度。

Mobile devices are widely distributed in sensor networks,a mobile sink proxy mechanism and network quality assessment strategies are proposed for the scenario of wireless sensor network of mobile sink.The mobile path of sink is guided by the quality of the network,and on this basis,we propose an angle based data collection algorithm from the standpoint of energy balance（Angle-based Data Collection algorithm for Mobile Sink ADC-MS）.Through the next hop node selection probability formula to optimize data collection path.Simulation results show that ADC-MS algorithm can effectively balance the energy consumption of the network and has higher level of reliable communication.
