Recently, the advancement of the development technologies for the smart sensor nodes that are small, low-power devices with abilities of environment sensing, data computing and wireless communication facilitates research for the wireless sensor network. Wireless Sensor Networks (WSN) are networks composed of such sensor nodes that have abilities to monitor and control the physical environment from the remote locations. Such networks make many applications possible in the scientific, medical, commercial, and military domains, for example, surveillance, smart home and offices, environment monitoring, and many others. In this paper, we present our proposed wireless sensor network architecture. It's basic operations, sensor ID assignment scheme and ID creation algorithm, and mobility protocol for the management of the sensor or relay nodes movement. We also suggest a power management scheme of our wireless sensor network architecture.
