Experimental analysis of an event tracking energy-efficient WSN

In Wireless sensor networks (WSN´s), various tiny wireless sensor nodes or motes collect the data from the surrounding areas, where they are deployed and forward the same towards the gateway. Various pieces of information, such as occurrences of various events in the field and associated aggregate values need to be extracted from the data collected by these motes in an end-to-end WSN solution. Furthermore, making this information available to authenticated remote users with reduced latencies and errors, is a challenging task. In this work, a an experimental WSN set up using light and accelerometer sensors is given and the experimental results of the same are presented. This paper also provides an analysis of XMesh protocol used in the experimental set up. In order to make the data collected by the WSN, accessible to a remote user, a solution based on a portable computer board, Raspberry Pi, is also given.
