The invention discloses a wireless sensor network cluster selection protocol for survivability analysis and on the basis of coverage. The protocol overcomes the defects that a cluster-head generating method in an LEACH protocol is random and only the number of survival nodes is taken into consideration. In the LEACH protocol, the node consuming the most energy is a cluster-head node, so that the node selected to be the cluster head is more prone to dying. In order to solve the problem, according to the protocol, the node with most neighbor nodes is selected to serve as the cluster-head node, and coverage is used for survivability analysis of a network, namely the ratio of the coverage area of the survival nodes and the coverage of all the nodes serves as a reference to evaluate survivability, so that the network guarantees that effective survival time of coverage is longer.
