Mobile Node for Wireless Sensor Network to Detect Landmines

Individual sensor nodes are low power devices which integrate computing, wireless communication and sensing capabilities to detect land mine. Such multiple nodes collectively form wireless sensor network. To detect landmine in ground surface, sensor node that able to sense the mine and to process the information locally are mounted on a mobile robot to scan the ground surface in the organized pattern resulting in detection of all the mines present in the proposed area which is synchronized by Infrared pills; the node can communicate to the data collection point (Sink) typically through wireless communication. The aggregation of such multitude of mobile nodes and a mobile sink forms a versatile mine detection unit. When the mine is detected the node routes it information to the hand held device (Base) through sink and stays in it position to help the demining crew to identify the position where the mine is present. When the demining crew presses a button the node continues in its pattern. KeywordsWireless sensor Network, Base, Sink, Node, Path pattern, IR-pills, Multi node.
