As mobile devices are becoming the popular portals for internet users, it has exposed some basic design limitations of the dominant Transmission Control Protocol. A crucial feature of TCP is the congestion control algorithm. The basic assumption is that, packet loss being nominal is a sign of network congestion. But in mobile wireless networks non congestion related packet losses due to varying signal power are dominant. This book provides an overview of the challenges and suggested optimization techniques for TCP in wireless network environments.
