Ultra Wide Band (UWB) technologies have attracted a lot of attention recently due to their large bandwidth and low emission, which are suitable for in-door, high-speed multimedia c...
We consider an ad-hoc network consisting of devices that try to gain access for transmission through a shared communication channel. We redesign randomized protocol of Cai, Lu and ...
A multi-hop relay network with multiple antenna terminals in a quasi-static slow fading environment is considered. The fundamental diversity-multiplexing gain tradeoff (DMT) is an...
The intent of this paper is to propose an energy-efficient routing protocol with data transmission security for wireless sensor networks. We create an energy and distance aware sin...
Given deterministic interfaces P and Q, we investigate the problem of synthesising an interface R such that P composed with R refines Q. We show that a solution exists iff P and Q ...
