摘要
文中针对物联网簇头节点无法有效处理数据或者失效导致网络可靠性下降的问题,提出了一种基于双机热备机制的簇头选举算法。该算法首先根据阈值在网络中选举出服务簇头,然后以服务簇头为基准选举出备用簇头,服务簇头和备用簇头互相监听,当服务簇头出现故障时由备用簇头接管服务簇头所有的业务,保证网络的可靠性。实验证明:该算法在网络连通性和保证网络的平均无故障时间方面都有一定的优化,一定程度上增强了网络的可靠性。
Due to the problem that the Internet of Things cluster head sink is unable to hand with the data correctly which leads to the low reliability of the Internet, the cluster head election based-on hot standby is put forward. At first, this arithmetic .will elect service cluster head in the website through threshold, then the standby cluster head is also made according to the service cluster head chosen. As the service cluster head and standby cluster head can monitor each other, the standby cluster head can replace service cluster head which sometimes has something wrong so as to ensure the reliability of the website. It is proved that this arithmetic can have some advantages in the aspects of the connectivity and MTBF of the Internet, so it strengthens the reliability of the Internet in a way.
