    Abstract

    Energy limitations in wireless sensor networks and the need for low latency in many applications require a uni¯ed ap- proach in the design of network protocols. In this paper, we propose a distributed wakeup schedule to accomplish a new topology control scheme. The aim is to increase the longevity of the network for a given upper bound on the average end-to-end delay. In the proposed scheme neither localization nor synchronization is required and only local information is used. In addition to its simplicity of imple- mentation, its energy overhead is negligible and it implicitly determines the routing paths. Our simulation results show that this protocol achieve signi¯cant improvement in the network lifetime compared to SPAN, an existing topology control mechanism.
