Energy-Aware Topology Control And Qos Routing In Ad-Hoc Networks

In order to reduce energy consumption in wireless ad hoc and sensor networks, the Topology Control (TC) remains one of the most important technique used. TC is able to construct network topologies, which have desired characteristics. It has also a dynamic ability to change the node transmitting range in a way to meet graph global property such as connectivity, while reducing energy consumption and radio interference. In this paper, we explore the energy-aware Topology Control in wireless ad hoc networks by formulating and solving the corresponding optimization problem. We propose an ILP formulation that minimizes the total transmission power needed by nodes to construct a topology that can meet Quality of Service (QoS) requirements between source and destination node pairs with less computational effort. The simulation results show that our algorithm has a better performance for data traffic in ad hoc networks. To evaluate the efficiency of our proposed algorithm, we compare its performance by simulation with another QoS model, using power efficiency measures. (C) 2015 The Authors. Published by Elsevier B.V.
