| 摘 要： | 从无线传感器网络的实际应用中的硬件构件成本及节点定位代价最小化出发,利用DV-Hop算法思想提出一种无需真实物理信标节点的无需测距节点定位算法.该算法利用高斯-马尔可夫移动模型的Sink节点周期性地发出当前位置信息分组,节点收到相应的位置信息分组时,利用RSSI的对数-常态分布模型计算与当前Sink节点的距离.节点根据...

| Abstract: | A range-free algorithm based on mobile sink node and DV-Hop localization scheme is proposed in order to decrease the hardware cost and implement complexity of WSN, the sink node mobiles in the network field based on Gauss - Markov mobility model, and sends location information periodically. Nodes sensing the information will compute the distance between sink and itself based on log-normal distribution model of RSSI. Those nodes who received more than 3 pieces of location information in short distance will be updated as virtual nodes. At last, the algorithm's efficacious and feasible was proved by the simulation experimental results. |
