Abstract. In this paper, we consider a two-layer hierarchy, ı.e. micro and umbrella layer, cellular system, and propose a new hand-off mechanism to minimize call blocking probabil...
An ad-hoc network is formed by a group of mobile hosts upon a wireless network interface. Previous research in this area has concentrated on routing algorithms which are designed ...
This paper describes a high performance CMOS differential input front-end, designed for optical wireless communications. The front-end achieves a 50 MHz bandwidth and a 400 K tran...

—We describe our experience from the implementation of the T-MAC protocol for wireless sensor networks in the open-source Castalia simulator. Notwithstanding the popularity of th...
A primary goal in the design of wireless sensor networks is lifetime maximization, constrained by the energy capacity of batteries. One well known method to reduce energy consumpt...
