An analysis of energy consumption for TCP data transfer with burst transmission over a wireless LAN

Abstract

SUMMARYA common strategy for energy saving in wireless network devices is to remain in sleep mode for as long as possible. The timing of packet transmission and reception depends on the behavior of the transport-layer protocols used by upper-layer applications. Therefore, understanding the relation between the behavior of the transport-layer protocols and energy efficiency using sleep mode is important for effective energy saving, especially when a wireless network interface (WNI) is activated in sleep mode at packet interarrivals. In this paper, we analyze the energy consumption of a client's WNI in Transmission Control Protocol (TCP) data transfer over a wireless LAN by focusing on the detailed behavior of TCP congestion control mechanisms. This model considers three situations: the WNI is activated in continuously active mode, in sleep mode, and in sleep mode with burst transmission. The latter is proposed as an effective method to improve energy efficiency, which lengthens sleep periods by transmitting and receiving multiple packets in a bursty fashion. Through numerical examples, we show that sleeping without modification of transmission timing reduces energy consumption in TCP data transfer by only around 10%, and that the burst transmission can contribute further 50% energy reduction.

Energy efficiency of TCP: An analytical model and its application to reduce energy consumption of the most diffused transport protocol

“…However, most of them work only for a specific scenario. Hashimoto et al [27] proposed a model for energy consumption of TCP with burst transmission over wireless networks. Ayadi et al [26] proposed a model for energy consumption of TCP in low power lossy networks where segment size can be tuned to optimize energy consumption.…”

Partitioned scheduling for sphere decoding with runtime constraints for practical MIMO communication systems

“…As expressed in (2), the conventional scheme allocates runtime to SD for the n-th symbol vector as the total remaining time excluding the minimum runtime of SD for the remaining K n symbol vectors. In addition, in practical frame-based communication systems, the frame size in the physical layer is usually set to be sufficiently large to reduce protocol overheads [13,14]. In the conventional scheme for this situation, SD for the symbol vectors in the posterior part of a frame is likely to operate with frequent ET because SD for those in the anterior part of a frame is allowed to exhaust the runtime allocated according to the MF strategy.…”

Energy efficiency and traffic offloading in wireless mesh networks with delay bounds

“…Another topical field is energy efficiency (EE), also known as ‘green’ networking. While the majority of the researchers have explored various aspects of cellular networks , it is also possible to find some approaches for reducing the power consumption of carrier‐grade WLANs , as well as for improving the energy performance of the WLAN protocols and procedures . Similarly, some studies have been presented on power saving solutions in WMNs , even though the majority of such studies focus on battery‐powered nodes rather than on plugged equipment (see e.g.…”

“…The idea is that the GW can be exploited, either as a replacement or as an addition to the CDN, to store the contents destined to the users, thus reducing the congestion of the Internet and improving the quality of the delivery service [2][3][4].Another topical field is energy efficiency (EE), also known as 'green' networking.
