Development of an Acceleration-based Wireless Sensor Node Platform

Abstract: A wireless sensor network is a distributed network made up of low-power consuming, low cost devices called sensor nodes which combine sensing, computation and communication. Sensor networks have enabled many applications, including remote tracking and monitoring of environments in real-time. It is of great value to use it where human is quite difficult to reach or where there are distributed sources of data. Power consumption and size are the most important consideration when nodes are designed for distributed wireless sensors. Consequently, it is of great importance to decrease the size of a node, reduce its power consumption and extend its life in network. This work describes the design and construction of an acceleration-based sensor node platform intended for use in sensor networks research. The system is made up of a hardware platform and a software stack for drivers and interfacing. The experiment results indicate that the node has the characteristic of high reliability, good stability and ultra low power consumption.
