Description
Summary:Sensor nodes are hardware devices and their source of energy is battery power . Nodes store, forward, report various environment related parameters to the sink, which is normally a base station, thus monitor the environment using co-operative information. A dynamic approach is suggested to regulate and decide broadcast radius . It can reduce collision . It can improve life span of network path and nodes on the path . even if the tasks are scheduled at the speed, still there will be the idle intervals. These idle intervals arise due to two reasons: 1) the idle intervals that are inherent to fixed priority schedules and 2) the idle intervals that arise due to run-time variations in execution time of tasks. All the tasks that are ready are kept in the "ready queue" in the order of their priority. The task that is currently being executed is called "active-task". At layer 1, consumption of energy is more . At layer 2, consumption of energy is slightly less . At layer 3, consumption of energy is low . Thus, Adjusting the operation mode of the nodes in wireless sensor networks can extend the networks lifetime effectively.
