Exploiting Multi-Channel Diversity in Spectrum-Agile Networks
—Recently, spectrum-agile (SA) networks have been recognized as a viable solution to the spectrum-scarcity problem in wireless communications. In SA networks, secondary (unlicens...

ALOHA with collision resolution (ALOHA-CR): theory and software defined radio implementation
A cross-layer scheme, namely ALOHA With Collision Resolution (ALOHA-CR), is proposed for high throughput wireless communications in a cellular scenario. Transmission occurs in a t...

Time-varying Opportunistic Protocol for maximizing sensor networks lifetime
We consider transmission scheduling by medium access control (MAC) protocols for energy limited wireless sensor networks (WSN) in order to maximize the network lifetime. Time-vary...
