Wireless Sensor Networks (WSNs) are a class of technology represented with set sensor nodes. The main objective these nodes is to collect data and monitor an environment's events. basic tasks node can handle sensing (humidity, temperature, fire, etc.), transmitting over short distances, performing limited processing. Common WSNs used in many application fields. resources the (low processing capacity, memory energy reserves) makes them underexploited compared WSNs' spectrum utilization....
