Mobile Computing and Communication Solutions for a Noisy Environment

Abstract

Business people today need an effective mobile computing system. This means that modern network systems must be comprised of both wired and wireless links Current transmission control protocols (TCP) implementations have been designed to work well in a wired environment in which error rates are very low and packet losses can be attributed to network congestion. In a wireless environment, there are higher error rates usually due to noise in the air. The loss due to congestion assumption is no longer correct in this environment. Current TCP implementations can not distinguish between a congestive loss and a wireless loss. Several strategies are currently being investigated to improve current TCP performance. One of the best candidates for common use is the Snoop Agent. The focus of my research has been to compare current TCP implementations with TCP combined with the Snoop Agent. Using a wireless test bed, the two implementations will be analyzed and tested to gauge their performance. Throughput and transmission times will be gathered and evaluated.
