Practical Exploitation of the Energy-Latency Tradeoff for Sensor Network Broadcast

As devices become more reliant on battery power, it is essential to design energy efficient protocols. While there is a vast amount of research into power save protocols for unicast traffic, relatively little attention has been given to broadcast traffic. In previous work [1], we proposed Probability-Based Broadcast Forwarding (PBBF) to address broadcast power save by allowing users to select a desired tradeoff between energy consumption, latency, and reliability. In this paper we extend our previous work in two ways. First, we introduce a new parameter that allows a tradeoff between reliability and packet overhead to give users more options. Second, we implement PBBF on the TinyOS platform [2] to evaluate it beyond the analysis and simulation from our previous work. Our evaluation demonstrates the tradeoffs possible using PBBF on sensor hardware.
