Abstract

Summary: Energy efficient communications become a challenge for both industries and researchers. Incorporating energy efficiency into the design of network protocols and architectures represents a relevant issue in networking research. Currently, very few works address energy efficiency as a fundamental feature of network protocols. This paper benchmarks energy efficiency of TCP to understand the parameters and operational mechanics that determine and contribute to energy consumption. We propose an analytical model with energy consumption to protocol operation cycles and novel optimization techniques for reducing energy consumption of TCP. The evaluation results, obtained from NS2 simulations, demonstrate that even minor modifications of the protocol behavior can bring significant savings of energy.

Abstract : In this paper, we propose an analytical model relating energy to protocol operation cycles and novel optimization techniques for reducing energy consumption of TCP. We find that, the proposed techniques can save up to 83% energy without any considerable impact on TCP throughput.
