A new algorithm of layered routing protocol in WSN

摘要

In wireless sensor networks(WSN), the measurement data of the neighbor nodes often have little differences. In view of this situation, a new algorithm called NNA based on layered routing protocol is proposed. By comparing the measurement data of the node with the cluster head's, if the difference of the data value is less than the threshold value set by the system, then the node will join to the cluster. The cluster-head rotates according to the energy consuming.
