Abstract--Two well-known problems that can cause performance degradations in IEEE 802.11 wireless networks are the exposednode (EN) and hidden-node (HN) problems. Although there ha...
Abstract— The 802.15.4 WSN standard provides optional reliability through positive acknowledgments. Since positive-ACKs are not designed for energy efficiency, there is significa...
While there are different research groups in the mobile computing community, most research requires mobile action data in terms of user calling and mobility patterns. Since collec...
—Via collaborative beamforming, nodes in a wireless network are able to transmit a common message over long distances in an energy efficient fashion. However, the process of mak...
—In distributed detection systems with wireless sensor networks, the communication between sensors and a fusion center is not perfect due to interference and limited transmitter ...
