节点在网络中可以充当数据采集者、数据中转站或者簇头节点(cluster head node) 的角色。作为数据采集者，数据采集模块收集周围环境的数据(如温度和湿度)，通过通信路由协议直接或间接将数据传输给远方基站(ba...

cluster-head node selection 簇头节点选择
If your servers are pooled in a compute cluster, the head node is the only crucial machine; the rest can start and stop and crash freely.
如果服务器部署在计算机集群中，那么最前端的节点是惟一的关键机器；其他机器可以随意启动和停止，崩溃了也不要紧。
While the timer reaches 0, the node becomes Cluster Head spontaneously.
时间率先衰减到0的节点则主动成为簇头。
In GAF, the network is divided into several grids, in which one node is chosen as the cluster head to represent the whole grid to communicate with other grids.
它将网络划分成若干个单元格，同一单元格内推举一个节点作为簇头，代替整个单元格实现通信功能。
