    AbstractOne of the most significant challenges in wide-scale Wireless Sensor Networks (WSNs) is to achieve energy efficiency in order to increase their lifetime and ensuring responsiveness. A very widely applied approach in this regard is to overload the region with numerous low-cost sensing devices that can communicate with each other wirelessly and coordinate amongst themselves in developing schedules for being asleep or active. The literature has numerous research works in this regard which aim to develop efficient sleep scheduling schemes. In this paper, we present an implementation of a grid-topology based cooperative Rank Based Sleep Scheduling (RBSS) protocol in which the nodes of every cell coordinate in a distributive manner, the decision making process of selecting the nodes that should stay active, while others sleep. The proposed protocol guarantees the WSN connectivity as well as the required coverage. Finally, we implement RBSS on a small scale grid using TelosB motes
