Energy-Efficient Unified Routing Algorithm for Multi-Hop Wireless Networks

In this paper, we develop an energy-efficient routing scheme that takes into account four key wireless system elements: transmission power; interference; residual energy; and energy replenishment. 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 four 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 and adapts to varying wireless environments. We study the impact of key wireless elements on routing, and show via simulations that EURo outperforms the state-of-the-art.
