A wireless sensor network consists of group of sensors, or nodes, that are linked by a wireless medium to perform distributed sensing tasks. The sensors are assumed to have a fixed communication and a fixed sensing range, which can significantly vary depending on the type of sensing performed. Duty cycle is the ratio of active time i.e the time at which the particular set of nodes are active to the whole scheduling time. With duty cycling, each node alternates between active and sleeping states, leaving its radio powered off most of the time and turning it on only periodically for short periods of time. In this paper, an ADB protocol is used to manage and control duty cycles as well as regulate , monitor on going traffic among the nodes by using adaptive scheduling. Thus congestion, delay can be controlled and efficiency and performance of overall network can be improved.
