Wireless sensor network systems, method for placing a plurality of sensor nodes in wireless sensor network system, and methods for computing sensing energy consumption per area of a plurality of sensor nodes

摘要

A wireless sensor network system, a method for placing a plurality of sensor nodes in a wireless sensor network, and a method for computing sensing energy consumption per area of a plurality of sensor node are disclosed. The wireless sensor network system includes a plurality of sensor nodes which are deployed at the same distance in a two-dimensional plane and have sensing areas of the same size, and an extra sensor node which has a sensing area of a smaller size than the size of the sensor nodes to sense a gap area which is not covered by the sensing areas of the sensor nodes.
