“…In general, the existing various load-balancing solutions can be categorized into adjustment methods and balancing metrics. The adjustment methods include cell breathing [7,14,15], AC [13,19], and AM [10][11][12]20] schemes. In [10], the authors introduced the following three weights for evaluating the load balancing of APs: (i) each AP serves the approximate number of MDs; (ii) the AP-served traffic; and (iii) bandwidth usage, in which the traffic load is divided by the AP bandwidth (e.g., the bandwidth is 20 units/s, two MDs, the total amount of flows is four units, and the bandwidth usage is 20%).…”

“…In general, highly overloaded AP may simply reject new association requests. If an AP is not overloaded then it grants association request from STA"s based on work-load status [9]. The request can be granted only when the predicted load level after the association does not exceed some predefined threshold.…”

Abstract-The popularity of IEEE 802.11 networks comes with its low cost, high data rate and seamless handoff. With heavily utilized infrastructure based wireless networks, number of users are increasing rapidly which makes available unlicensed spectrum band more congested. Moreover, most of the IEEE 802.11 standards (b/g/n) operate on 2.4 GHz which has subject to interference with other services like Bluetooth, sensor networks and cordless phones. Hence, the performance of IEEE 802.11 MAC should be enhanced with respect to interference and spectral scarcity. In general, IEEE 802.11 networks operate on either DCF (Distributed co-ordination function) or PCF (Point co-ordination function) mode. This research paper mainly focuses on PCF mode IEEE 802.11g standard and explains the necessity of amendment in terms of frequency, throughput, net bit rate, maximum indoor range and maximum output range. OPNET Simulator is used to calculate network load, throughput and medium access delay. Moreover, calculated performance metrics are compared with different user probability for IEEE 802.11g networks.Index Terms-IEEE 802.11g, MAC, throughput, network load.

“…Li-Hsing Yen et al [6] proposed that balancing AP traffic loads effectively can increase overall system performance. The metrics that had been taken into account for load balancing in several schemes are the number of users associated with an AP, the bandwidth that a new user can get from an AP if that user is connected with that AP.…”
