Abstract

A common strategy for energy saving for wireless network devices is to stay in sleep mode for as long as possible when no data is being transmitted or received. The timings of packet transmission and reception are not determined only by the behavior at the physical and the data link layers; they strongly depend on the behavior of the transport-layer protocols used by upper-layer applications. For effective energy saving, therefore, it is important to understand the relationships between the behavior of the transport-layer protocols and energy efficiency. One effective method for lengthening the idle interval is by transmitting and receiving multiple packets in groups, which is called burst transmission. In this paper, we analyze the energy consumption of TCP data transfer with burst transmission over a wireless LAN. By comparing the energy consumption with and without burst transmission, we show that burst transmission can reduce the energy consumption in TCP data transfer by approximately 60 %. We also discuss which part of wireless LAN devices should be improved for effective energy saving.

无线局域网中TCP突发传输的能效分析

无线网络设备节能的一个常用策略是在没有传输或接收数据时尽可能长时间地保持休眠模式。数据包传输和接收的时间不仅由物理层和数据链路层的行为决定;它们强烈依赖于上层应用程序使用的传输层协议的行为。因此，为了有效地节约能源，理解传输层协议的行为与能源效率之间的关系是很重要的。延长空闲时间间隔的一种有效方法是分组发送和接收多个数据包，这种方法称为突发传输。本文分析了无线局域网中突发传输TCP数据传输的能耗。通过比较突发传输和非突发传输的能耗，我们发现突发传输可以将TCP数据传输中的能耗降低约60%。讨论了无线局域网设备中哪些部分需要改进才能有效节能。
