A Channel Allocation Mechanism for Cellular Networks

A Channel Allocation Mechanism for Cellular Networks

In cellular networks, call blocking causes lower customer satisfaction and economic loss. Therefore, the channel allocation for call block avoidance is an important issue. This study proposes a mechanism that considers the real-time traffic information (e.g., traffic flow and vehicle speed) and the user behavior (e.g., call inter-arrival time and call holding time) to analyze the adaptable numb...

DonorList: A New Distributed Channel Allocation Scheme for Cellular Networks

Channel allocation in cellular radio networks

-In this article, two efficient heuristic algorithms are suggested for the channel allocation problem which minimizes the average blocking probability of the whole network subject to the co-ebannel, adjacent-site and co-site interference constraints, given the number of available channels. We convert this problem into a convenient form using the piecewise linearization technique and the concept...

Hybrid Channel Allocation in Wireless Cellular Networks

The enormous growth of mobile telephone traffic, along with the limited number of channels available, requires efficient reuse of channels. Channel allocation schemes can be divided into three categories: Fixed Channel Allocation (FCA), Dynamic Channel Allocation (DCA) and Hybrid Channel Allocation (HCA). In HCA, channels are divided into two disjoint sets: one set of channels is assigned to ea...

Uplink Channel Allocation Scheme and QoS Management Mechanism for Cognitive Cellular-Femtocell Networks

Cognitive radio and femtocell are promising technologies which can satisfy the requirements of future mobile communications in terms of dynamic spectrum sharing and high user density areas. Providing quality-of-service (QoS) guaranteed realtime services is challenging issue of future cognitive cellularfemtocell mobile networks. In this paper, we introduce a user’s QoS management mechanism used ...
