Embodiment Construction

[0032] 1. Architecture

[0033]The invention seeks the dynamic balance in the dynamic wireless sensor network. Many nodes interact with the environment and collect information and forward it to the cluster head node. In the present invention, the wireless sensor network is divided into clusters, specifically with the aggregation node as the center; then the size of the cluster is determined to vary with the density, and the cluster radius is small where the density is high, and the cluster radius is large where the density is small; finally there is a cluster and the location to the sink node to determine the specific location of the cluster. The cluster head node needs to process a large amount of data and forward it to the network management node, which consumes a lot of energy. The immune algorithm makes the selection of the cluster head economical in terms of energy consumption. If the key management is connected to the cluster head selection, the cluster head can Ensure...

Abstract

The invention provides a mobile sensor network clustering method based on the immune algorithm. The cluster division method adopts the uneven dynamic division of the cluster size that changes with the node density, and qualitatively provides the relationship between the cluster size and the node density. , which solves the problems of energy waste and incomplete information brought about by traditional methods; for the selection of cluster heads, the strategy of key-communication immune algorithm is introduced here. Secrecy is a very useful aspect, and the introduction of key management is beneficial The security of the whole network is guaranteed; the setting of the immune operator in the immune algorithm makes the selection of the cluster head both economical and reasonable.
