For sensornets with heterogeneous duty cycles, sensor nodes wake up with different sleeping periods, which combined with unreliable links, making it very challenging to enhance the network performance. This paper presents a new opportunistic routing protocol, called EOF (Efficient Opportunistic Forwarding), which mainly involves a forwarding metric that can efficiently exploit the single-hop forwarding...
In low duty-cycle sensor networks, sensors sleep most of their time; it is consequently hard for sensors to maintain always-awake communication links. One major challenge is therefore to design communication algorithms to reduce the delivery delay. In this paper we propose and evaluate a delay-aware routing algorithm for low duty-cycle sensor networks. The proposed algorithm first organizes the network...
