Abstract

The wireless networking is embedded into a wide variety of common devices. In many embedded networking situations, there have been increasing demands on the embedded wireless system for video streaming. However, it is inherently vulnerable to loss from dynamic wireless channel. In order to alleviate the effect of losses in the transport layer, the error control schemes are used. However, since each error control scheme shows different performance, a suitable scheme should be selected and applied. In this paper, we propose and implement a network-adaptive selection of transport error control (NASTE). To verify the feasibility of the proposed NASTE, we have implemented it in the embedded system which includes IEEE 802.11g WLAN environment. The experimental results indicate that the proposed mechanism can enhance the overall transport performance by recovering packet losses.
