Wireless sensor network

By Martin Hruška


Wireless sensor network (WSN) consist of a mesh of a several powerful devices (denoted as base stations or sink) and a high number (1000 - 1000000) of a low-cost devices (denoted as nodes or motes), which are severely constrained in processing power, memory and energy. The nodes are equipped with an environment sensor. Events recorded by the sensor nodes are locally aggregated and then forwarded to a base station for further processing. WSNs are expected to be in wide use for a multitude of different scenarios. Project target is to analyse possibility of wireless transfer of digitalised data from sensors. Work contains and compares: Wi-Fi, , WiMAX, ZigBee, GPRS, radio net and IrDA. The work will design a wirelless network with data collection from sewerage plant sensors in small rural agglomeration and transfer data to the central dispatching. The work will suggest several options and compare their advantages and disadvantages
