A major problem for TCP connections over wireless links is that errors introduced by the wireless channel interfere with the TCP protocol, leading to reduced data rates and power wastage. Based on accurate simulations for the TCP and IEEE 802.11 MAC protocols, we discuss recipes to optimize transmission. It is argued that the best approach is to restrict(More)
Even in light-weight wireless computing applications, processing of network-protocols becomes more and more computationand energy-hungry, with increasing data rated and the need for security operations. To cope with such requirements and as alternative to heavyweight computation systems we propose an embedded system that is build for fast network-processing(More)
A known problem for TCP connections over wireless links is that errors in the wireless channel interfere with the TCP protocol even for minor packet loss. In the first part of this paper we evaluate how the data rate reduction depends on the channel delay. For comparatively short delays in the order of 100 ms, the decrease of the throughout is noticeable(More)
