We present the results of a performance evaluation of link layer error recovery over wireless links. Our analysis is based upon a case study of the circuit-switched data service i...
Dynamic spectrum access (DSA) is an integral part of cognitive radio technology aiming at efficient management of the available power and bandwidth resources. The present paper d...
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...
