Abstract—WiMAX with femto cells is a cost-effective nextgeneration broadband wireless communication system. Cognitive Radio (CR) has recently emerged as a promising technology to...
Virtual private networks (VPNs) allow two or more parties to communicate securely over a public network. Using cryptographic algorithms and protocols, VPNs provide security servic...
The cognitive radio (CR) paradigm calls for open spectrum access according to a predetermined etiquette. Under this paradigm, CR nodes access the spectrum opportunistically by cont...
—Recently, broadband analog network coding (ANC) was introduced to utilize high-data rate transmission over the wireless – frequency selective fading – channel. However, ANC ...
Clock synchronization is critical for Wireless Sensor Networks (WSNs) due to the need of inter-node coordination and collaborative information processing. Although many message pa...
