Quality of Service Aware Traffic Scheduling Algorithm for Heterogeneous Wireless Networks

Abstract

Recent developments in multiple technologies evolving these days provide users with broadband services of high quality and seamless mobility. Wireless networks comprising of third generation (3G) and fourth generation (4G) provide wide coverage and good mobility capabilities. All these high quality wireless networks have been deployed within one region overlapping each other, hence generating a heterogeneous network for wireless access which can be represented as 4G heterogeneous network. The architecture of the system is such that it should support bulk data transfer. Although the Worldwide Interpretability for Microwave Access (WiMax) supports huge data transfer but still there is problem with the node request and service management. It becomes a sophisticated task for the nodes to handle number of requests at the same time. This work focuses on different aspects of the WiMax network and scheduling algorithms with hybrid architecture which is a combination of the First Come First Serve (FCFS) and Round Robin (RR) Algorithm. An analytical study of the number of jobs scheduled and completed along with accuracy for FCFS, RR and Hybrid algorithm is represented. The work is preceded by designing architecture of Long Term Evolution (LTE) which is a recently evolving technology which ensures the reliable delivery of the heterogeneous traffic services with high speed data rate and lower delays through their mobile and other hand held devices. The key feature of LTE is its traffic engineering which is used for effectively managing the network resources for efficient utilization. When LTE expertise has arisen there are some prevailing problems to be taken care of i.e. load balancing and traffic scheduling. Even LTE is the debauched technology, but it is also been anguishing from these problems. newline
