A Survey on Quality of Service Provision in 4G Wireless Networks

Abstract: Worldwide many mobile operators, industry experts, and researchers have diverse visions of potential 4th generation (4G) features and its implementations. 4G networks will be incorporating advanced Internet Protocol version 6 (IPv6) protocol and the signaling will be done through Internet Protocol (IP). There are several key challenges in implementing 4G heterogeneous network. Few of these problems are all IP network, integration across different topologies, security and Quality of Service (QoS). This paper gives a survey and classification of the important QoS approaches proposed for 4G networks. Classification is based on the work done in each protocol layer and Cross Layer Design (CLD) approach. Finally, this paper presents outcomes of survey which includes significant observations, limitations and idea of further research in improving QoS in 4G networks.
