Reliable Multicast in Wireless Sensor Networks

Multicasting in Wireless Sensor Networks WSNs is an efficient way to disseminate the same data to multiple receivers. For critical tasks such as code updates, reliability would be a desirable feature, in order to use multicasting for such scenarios. Due to the nature of WSNs, several problems exist that make...

TCP Support for Sensor Networks

Communication between sensors and controlling entities at the edge or outside the sensor network is needed for reliable remote sensor node management and reprogramming. TCP would be useful for tasks, where reliable unicast is appropriate, but the high bit error rates in wireless sensor networks lead to energy inefficiencies reducing...

A Smart TCP Acknowledgment Approach for Multihop Wireless Networks

Reliable data transfer is one of the most difficult tasks to be accomplished in multihop wireless networks. Traditional transport protocols like TCP face severe performance degradation over multihop networks given the noisy nature of wireless media as well as unstable connectivity conditions in place. The success of TCP in wired...

Energy-Efficient TCP Operation in Wireless Sensor Networks

Many applications of wireless sensor networks require connectivity to external networks to let monitoring and controlling entities communicate with the sensors. By using the TCP/IP protocols inside the sensor network, external connectivity can be achieved anywhere in the sensor network. In such IP-based sensor networks, TCP can be used for...

Whispers will not kill fair use

Boingboing reports, via Google lawyer William Patry, that some large entertainment companies have launched a "whisper campaign" aimed at killing fair use. Governments are being told, in effect, that the U.S. Copyright law is incompatible with the Berne Convention, an international treaty on which copyright laws worldwide...

File-swapping gets supercharged on student network

File-swapping gets supercharged on student networkDeja Vu all over again?[i]"Internet2 is for research. It's not for downloading music," said Marc Ray, a senior computer support specialist at Florida State University. He's still evaluating the program, he said. "The fact is the network cost a lot of money, and downloading games...
