The Research for Deployment Strategy Based on Maximization Lifetime in Hierarchical Structure Wireless Sensor Network

A deployment strategy of hierarchical structure wireless sensor network. (HSWSN) is studied, HSWSN are composed basic station (BS), relay devices (RNs) and sensors (SNs). In this paper, the mode of system and energy consumption are proposed, the deployment strategy especial relay devices is proposed, and some important such that energy consumption density (ECD), distribution probability of RN consumption in infinitesimal region, and subarea concept are proposed. Adopting add number of RN in special point to be relay in subarea can decrease ECD, to prolong lifetime for integration HSWSN. The results of simulation experiment show that variance of ECD and relative lifetime is all to lessen. This paper provides a method for random deployment of hierarchical structure wireless sensor network.
