TLDR
An attempt has been made to propose a light weight call admission algorithm for increasing the number of admitted call in this type of constrained scenario and the proposed algorithm is supposed to work satisfactory for a GSM standard telephone network in terms of adaptability,Number of admitted customer and the involved cost overhead.Abstract:
Occasional user influx in a cell in a public place like a football stadium congests the network and even leads towards total disruption of services. However, for this temporary high user concentration, the service providers would not be interested in maintaining a huge infrastructure. This demands an efficient, provisional capacity enhancement technique without any additional infrastructure towards increasing service accessibility to maximum number of users. In this paper, an attempt has been made to propose a light weight call admission algorithm for increasing the number of admitted call in this type of constrained scenario. The proposed algorithm is supposed to work satisfactory for a GSM standard telephone network in terms of adaptability, number of admitted customer and the involved cost overhead.read more

Cell Breathing Techniques for Load Balancing in Wireless LANs
Yigal Bejerano,Seung-Jae Han +1 more
TL;DR: This paper presents a new load balancing technique by controlling the size of WLAN cells (i.e., AP's coverage range), which is conceptually similar to cell breathing in cellular networks, and develops a set of polynomial time algorithms that find the optimal beacon power settings which minimize the load of the most congested AP.

A dynamic channel-borrowing approach with fuzzy logic control in distributed cellular networks
Yao-Tien Wang,Jang-Ping Sheu +1 more
TL;DR: This paper develops a method to predict the cell load and to solve the channel-borrowing problem based on the fuzzy logic control, and demonstrates that the algorithm has lower blocking rate, less updated overhead, and shorter channel acquisition delays.

Performance between circuit allocation schemes for half- and full-rate connections in GSM
TL;DR: Fair repacking is found to be the fairest and most efficient, however, the best-fit scheme, while being somewhat less efficient and fair, is simpler to implement.
Dynamic half-rate connections in GSM
TL;DR: A new queueing model is developed based on a reduction of the state space, which makes an efficient approximation possible and turns out to be extremely accurate, computationally efficient and approximately insensitive with respect to the holding time distribution.
