Research on Environment-Adaptive Architecture Model of Wireless Sensor Networks

The defects in traditional Wireless sensor networks (WSN) architectures are firstly studied, and then the typical requirement objectives of WSN are acquired by analysis. Because the WSN is mostly intended for variable and inhospitable environments, where persistent and continuous energy supply is lacking, the environment adaptive and energy efficient capabilities are integrant for WSN architecture. According with other objectives scalability and service-customized, an environment adaptive, energy efficient, hierarchical structure and sub-facets functions architecture model EAWNA is proposed. Furthermore, the design methods, general characteristics and functions of every lay or every module are described and discussed.
