In wireless sensor networks, some sensor nodes are put in sleep mode while other sensor nodes are in active mode for sensing and communication tasks in order to reduce energy consumption and extend network lifetime. This approach is a special case (k=2) of a randomized scheduling algorithm, in which k subsets of sensors work alternatively. In this paper, we first study the randomized scheduling algorithm...
Based on the application of active networks in congestion control, this paper introduces the traditional congestion control policy and analyses their principles and feasibilities. Active networks congestion control policy introduces the active detection and the passive notification mechanism, the random early detect (RED) queue management and the load balance technology based on the traditional congestion...
In this paper, we study a randomized scheduling algorithm, and analyze the problem of maximizing network lifetime under quality of service constraints such as bounded values of detection delay, detection probability, and network coverage intensity in wireless sensor networks. We show that the optimal solutions exist and provide the conditions of the existence of the optimal solutions.
