摘要
针对云计算的传感网络通信节点中会出现单个云节点的通信坏死,造成通信过程会根据全程路由距离选择其他替代节点,选择过程随机性较大,很难保证选择到最优节点,造成通信效率不高,提出一种基于云节点损坏小区域替代的传感通信算法;通过周边最近节点组成一个节点可替代的区域,通过计算小区域内最为有效的距离,选择最优的云计算替代节点,保证通信效率;实验结果表明,运用该算法能够对大规模的云计算传感网络中出现的死节点进行迅速替换,提高了传感网络信道的通信效率。
Cloud computing to the sensor network communication node, there will be a single cloud node communication necrosis, causing the process will he the whole distance communication according to choose other node, the selection process randomness is bigger, communica tion efficiency is not high. In order to improve the communication network computing clouds efficiency is proposed based on a small regional cloud automatic distance test alternative to the node network communication agreement. Through the surrounding recent node form a node can substitute the area, through the calculation small area most effective distance, choose appropriate cloud connected alternative node. En sure that communication efficiency. The experimental results show that the method can be used to large computing clouds appear in the death of the network nodes are replacing, improve the efficiency of the node channel communications.
