针对无线传感器网络现有关键点判定方法中,判定指标比较单一,容易导致关键点判定结果不全面的问题,综合考虑节点局域信息和能量因素,提出一种新的关键点判定算法。此算法首先利用节点自身度与其邻居信息对节点局域信息进行建模,接下来结合节点剩余能量和节点失效后网络能耗的变化,建立能量因素模型,最终得到一个综合的关键点判定模型。利用Matlab仿真平台与其他算法进行对比仿真,结果表明该算法能使关键点判定更加全面,同时验证在保护由此算法判定所得关键点时,网络能够表现出强抗毁性,验证此算法的有效性。
In the existing key node decision methods for wireless sensor network
the judgment index was so single that the result judged was deficient.In order to solve this problem
a new key node decision algorithm(KNDA)based on local information and energy factor was proposed.Firstly
the local information model based on the degree and neighbor information of node was established.Secondly
according to the residual energy of node and the change of network energy consumption after the node failed
the models of energy factors were established.Finally
an aggregative key node decision model was formed.Extensive simulation experiments were carried out in the MATLAB simulation platform
by comparing with other algorithms
the results verify that the key nodes obtained by this algorithm are more sufficient.Meanwhile when the key nodes judged by KNDA are protected
the network can show strong invulnerability.
