Towards energy efficient and robust routing with delay guarantees in adhoc and sensor networks
Additional Document Info
Saving energy while providing end-to-end delay guarantees and robust operation have long been regarded as of paramount importance in real-time adhoc and sensor networks. In this paper we explore how rate-adaptation can save energy in adhoc and sensor networks that have real-time requirements, and how robustness requirements, achieved by multipath routing, affect the achievable energy savings. We formulate the problem of finding the most energy efficient data rate for each link, propose an adaptive data rate selection algorithm, and demonstrate that our scheme can save up to 15% energy, when compared with state of art, while still meeting the end-to-end delay guarantees.
