Abstract

Wireless mesh networks have been shown to be an appropriate technology for rural areas. However, in most African countries, electricity is scarce in rural areas. A candidate solution to the power-constraint problem in these areas is the use of solar/battery-powered nodes. Different protocols at different layers have varying effects on the energy consumption of the nodes. However, it is not clear how these protocols affect the energy consumption of a battery-powered node in a testbed environment. This paper evaluates the influence of TCP and UDP on the lifetime of battery-powered nodes when subjected to different transmission power levels and payload sizes. An indoor testbed evaluation shows that UDP at maximum transmission power with minimum payload performs best with regards to the node lifetime, TCP at maximum payload with maximum transmission power performs best with regards to packet delivery ratio and throughput and TCP at maximum transmission power with minimum payload consumes the least transmission energy.

电池供电无线网状网络中传输层协议的能效评估

无线网状网络已被证明是一种适合农村地区的技术。然而，在大多数非洲国家，农村地区电力匮乏。在这些领域，功率限制问题的一个候选解决方案是使用太阳能/电池供电节点。不同层的不同协议对节点能耗的影响是不同的。然而，目前尚不清楚这些协议如何影响测试平台环境中电池供电节点的能耗。本文评估了TCP和UDP在不同传输功率和负载大小下对电池供电节点寿命的影响。室内试验台评估表明，UDP在最大传输功率和最小负载下在节点寿命方面表现最佳，TCP在最大传输功率和最大传输功率下在包投递率和吞吐量方面表现最佳，TCP在最大传输功率和最小负载下消耗的传输能量最少。(6页)
