Abstract

ABSTRACT: To provide broadband access services to customers, which resides residential and enterprise field, Worldwide Interoperability for Microwave Access (WiMAX) is one of the famous wireless technologies. WiMAX can provide high-speed data rate with large-scale coverage such that it contains a high transmission range as well as it supports high mobility with a large number of nodes. It requires scheduling algorithm in the MAC layer of its protocol stack because the number of users that want service is high in number. One of the most used scheduling algorithms is the Earliest Deadline First (EDF) but it contains certain performance limitations. As well as there is a need for security before allocation of bandwidth to the users because WiMAX is a wireless technology and may be vulnerable to lots of security attacks and if once the bandwidth is allocated to any malicious user, then the system of WiMAX communication will be under dangerous attacks. In this paper, we proposed a secure heuristic earliest deadline first uplink scheduler in the MAC layer of the WiMAX with some authorization procedures. The proposed scheme protects the allocation of bandwidth to any malicious node such that the system will be prevented from security attacks like Denial of Service (DoS), flooding attack, etc., as well as it will use heuristic approach for scheduling. Therefore, it can efficiently schedule user's request and provide fairness to the WiMAX system and we called as Secure Heuristic EDF Uplink Scheduler (SH-EDF). The performance of SH-EDF uplink scheduler will be evaluated in the provisions of various performance metrics.
