17 A solution to channel assignment problem in cellular networks is self-organizing channel assignment algorithm with distributed control. In this paper, we propose three cellu-19 lar learning automata based dynamic channel assignment algorithms. In the first two algorithms, no information about the status of of channels in the whole network will 21 be used by cells for channel assignment where...
This paper presents a novel specification-based investigation logic and applies it to tackle abuse of channel assignment protocols in multi-channel wireless networks. The investigation logic looks into malicious operations that violate the specification of channel assignment protocols. With logged operations, it reconstructs the process of channel assignment as an information flow that captures...
Terminal assignment problems are placement problems in channel routing in which each one of n entry terminals on one side of the channel is assigned to one of m exit terminals on the other side of the channel. We study solutions to terminal assignment problems that minimize the density. a cost measure closely related to the minimum channel width needed to wire the resulting channel routing prob...

Existing frequency assignment efforts in wireless sensor network research focus on balancing available physical frequencies among neighboring nodes, without paying attention to the fact that different nodes have different traffic volumes. Ignoring the different traffic requirements in different nodes in frequency assignment design leads to poor MAC performance. Therefore, in this paper, we are ...
Introduction: HIPERLAN (high performance radio local area network) is a wireless LAN standard recently adopted by the European Telecommunications Standards Institute (ETSI) [1]. HIPERLAN (type 1) operates in 150MHz of spectrum in the 5.15–5.30GHz band, with five TDD channels capable of data transmission at speeds of up to 23.5Mbit/s. HIPERLAN uses a (31, 26) BCH code to encode data to be transm...
In this paper, we proposed a 2-D analytical model for electrical characteristics such as surface potential, electric field and drain current of Silicon-on-Insulator Tunnel Field Effect Transistor (SOI TFETs) with a SiO2/High-k stacked gate-oxide structure. By using superposition principle with suitable boundary conditions, the Poisson’s equation has been solved to model the channel r...
