Abstract: Wireless sensor networks need deploy suitable numbers of nodes to assure the connectivity of networks in stochastic-deployed environments. The connectivity is the guarantee of service and function of wireless sensor networks. The paper puts forward a stochastic-deployed mathematic model based on different conditions. Simulation tests demonstrate that the model is valid and it provides the basic theory for stochastic-deployed application in wireless sensor networks.

Key words: wireless sensor networks, connectivity, stochastic deployment
