Abstract
In many papers, the idealized binary perfect-reception-within-range model used in common network simulation. But many studies have revealed the existence of three distinct reception regions in a wireless link: connected,transitional,and disconnected. So,we propose a communication mechanism in the dynamic clusters based on link quality in WSN target tracking. A voting approach was developed for the cluster head selection by taking the LQI into consideration in the paper. When the cluster members communicate with cluster head, we adopt multi-hop reliable communication way. We used MATLAB to simulate the improve solution. The simulation results show that the new mechanism reduce the network packet loss rate、the network energy consumption and the network delay.关键词
