A comparison of mechanisms for improving TCP performance over wireless links
TLDR
Reliable transport protocols such as TCP are tuned to perform well in traditional networks where packet losses occur mostly because of congestion. Expand

Improving TCP/IP performance over wireless networks
TLDR
We propose a simple protocol, called the snoop protocol, that improves TCP performance in wireless networks by caching packets at the base station and performing retransmissions across the wireless link. Expand

Synopsis diffusion for robust aggregation in sensor networks
TLDR
We present a general framework for achieving signi.cantly more accurate and reliable answers by combining energy-efficient multi-path routing schemes with techniques that avoid double-counting. Expand
