Wireless Sensor Networks (WSN) is different than the Cellular Networks as I mentioned earlier. A WSN is composed of a large number of sensor nodes that communicate using a wireless medium (air). The sensor nodes are deployed randomly in the environment to be monitored. The sensor nodes distributed in ad hoc structure. In WSN there is no base station and not all nodes hear each other. The WSN is a multi-hop network. Basic part of my code is to randomly place the sensor nodes in the given space then connecting each two nodes if the distance between them less than or equal to the communication radius.
