Unified Energy-Efficient Routing for Multi-Hop Wireless Networks

Abstract

In this paper, we develop an energy-efficient routing scheme that takes into account three key wireless system elements: transmission power; interference; and residual energy. Since energy is a scarce resource, many energy-aware routing algorithms have been proposed to improve network performance. However, previous algorithms have been designed for a subset of these three main elements, which could limit their applicability. Thus, our contribution is here to develop a unified routing algorithm called the Energy-efficient Unified Routing (EURo) algorithm that accommodates any combination of these above key elements. We show via simulations that EURo outperforms the state-of-the-art.
