Limitations of special-purpose instructions for similarity measurements in media SIMD extensions
Microprocessor vendors have provided special-purpose instructions such as psadbw and pdist to accelerate the sumof-absolute differences (SAD) similarity measurement. The usefulne...

What does using TCP as an evaluation tool reveal about MANET routing protocols?
Past research studying the operations of TCP over wireless/mobile ad hoc networks has shown that TCP cannot be adopted as-is for use in mobile ad hoc networks (MANET) to achieve r...

On optimal communication cost for gathering correlated data through wireless sensor networks
In many energy-constrained wireless sensor networks, nodes cooperatively forward correlated sensed data to data sinks. In order to reduce the communication cost (e.g. overall ener...
