A Link Level Efficiency Measure for Wireless Home Area Networks

Abstract

In order to evaluate and to compare the performance of communication systems and the impact of improvement methods a suitable measure is essential. This paper describes an efficiency measure for the analysis and assessment of wireless home area networks. In contrast to existing definitions suitable for this specific application area, the proposed efficiency measure accounts for the resources spent to achieve the actual performance as well as for the severity of the transmission task. On the basis of this definition we assessed and compared wireless systems as well as specific optimization methods in different national and international research projects. Besides the definition, we will point out the significance of the measure and demonstrate its usage by means of typical examples.

Efficiency of frame aggregation in wireless multimedia networks based on IEEE 802.11n

“…for frame aggregation. The derivation of the link efficiency and examples are given in [4]. The definition of the link efficiency Ș L is as follows: …”

“…They neither provide a basis for link adaptation nor for a fair comparison of different improvement methods. Therefore, we evaluate different frame aggregation configurations on basis of the link efficiency defined in [4].…”

“…In contrast, this paper analyzes the efficiency of frame aggregation by taking into account the resources spent to achieve the performance as well as the complexity of the transmission task. As an appropriate efficiency measure, we use the link efficiency defined in [4]. This efficiency measure is topology independent and can be applied to different use cases.…”
