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...
— Recent studies have shown that designing a Medium Access Control (MAC) protocol combined with a cooperative approach may improve the attainable network throughput, despite redu...
– MIMO (Multiple Input Multiple Output) is capable of offering several-fold increase in spectral efficiency over singleantenna systems through spatial processing. However, curren...
Security is a major, frequent concern in extensible software systems such as Java Virtual Machines and the Common Language Runtime. These systems aim to enable simple, classic app...
The concept of context-dependent access control has emerged during the last years: Information about the state of a process model of a working environment is combined with general ...
