THE REASEARCH OF HIERARCHY MODEL FOR AD HOC NETWORK MONITORING BASED ON CLUSTERING

摘要

Ad hoc network has dynamic topology and large-scale nodes, for the purpose of monitoring and measurement in Ad hoc network, this paper proposes a new frame method of hierarchy model for monitoring, i.e., clusterhead selection mechanism. The mechanism designed a weight formula to handle the comprehensive update considering several factors such as distance, mobile rate, energy during the model establishment period, and three kinds of partial update means in real-time attributes management. It enhances load balance and structure stability in monitor hierarchy model and reduces calculation cost for unnecessary update. The simulation results show that the model using clusterhead selection mechanism was stable and efficient, which could apply to muti-scale networks, achieve conveniently and flexible deployment in Ad hoc network measurement system.
