Wireless sensor network consists of a group of sensors which has the capability to sense and transmit the real time information to the server. Scheduling in sensor gateway always remains a challenge as it needs to consider the optimal channel utilization of the sensor motes. Most of the scheduling algorithm in the sensor gateway is based on node’s duty cycle, i.e., active time, nap time and idle listening period of the detectors. The duty cycle scheduling is varied randomly based on the data arrival with FIFO queues as common consideration for diverse traffic loads.
