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...

A solution to channel assignment problem in cellular networks is self-organizing channel assignment algorithm with distributed control. In this paper, we propose three cellular learning automata based dynamic channel assignment algorithms. In the first two algorithms, no information about the status of channels in the whole network will be used by cells for channel assignment whereas in the thi...

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 investigate the sub-channel assignment and power control to maximize the total sum rate in the uplink of two-cell network. It is assumed that there are some sub-channels in each cell which should be allocated among some users. Also, each user is subjected to a power constraint. The underlying problem is a non-convex mixed integer non-linear optimization problem which does not h...

Non-cooperative channel assignment, i.e., channel assignment for selfish wireless devices, is highly challenging, especially in multiple collision domains. In this paper, we study the problem of noncooperative multi-radio channel assignment in multiple collision domains and focus on the fairness issue. We first conduct an analysis of the fairness property of the system assuming no incentive-com...

—Channel assignment assigns proper channels for interfaces, which helps dramatically reduce interference and improve network capacity. Routing selects proper paths for packet delivery, which can also help improve network capacity. In order to reduce computational complexity of joint multicast routing and channel assignment, multicast routing and channel assignment are regarded as two separate ...
