Abstract :
Wireless ad hoc networks, especially sensor networks, are subject to limited power supply and interference. In this paper, we derive a suitable link cost for energy-efficient routing in ultra wideband (UWB) networks, based on the bit error rate (BER) expression of a detailed physical layer model of UWB under additive white Gaussian noise (AWGN) and multi-user interference (MUI). With this link cost, we introduce an optimal interference-aware routing algorithm, which is capable of routing data packets from source to destination, using minimum energy per bit and at the same time achieving the end-to-end BER requirement. A simple interference-aware routing algorithm is also introduced. From our result, it is shown that our interference-aware routing algorithms consume 3 dB less energy than some simple routing algorithms
