Throughput optimized monkey search optimization for multi-media scheduling

Interest in broadband wireless access (BWA) has been growing due to increased user mobility and the need for data access at all times. IEEE 802.16e based WiMAX (Worldwide Interoperability for Microwave Access) networks promise the best available Quality of Services (QoS). WiMAX network has several QoS (Quality of Service) mechanisms at the Media Access Control (MAC) level for guaranteed services for voice, video and data. The problem of assuring QoS is basically that of how to allocate available resources among users in order to meet the QoS criteria such as throughput and delay requirements. There is no specific IEEE standard for scheduling mechanism and leaves it for implementer or vendor. Scheduling is therefore of special interest to all WiMAX equipment makers and service providers. The proposed scheduling algorithm in this paper-Monkey Search Optimisation (MSO) is designed to achieve the QoS guarantees, Fairness among QoS classes, to maximize Throughput and to minimize algorithm complexity and system scalability. This paper also discusses the key issues and factors to be considered for scheduler designers
