IROISE: a new QoS architecture for IEEE 802.16 and IEEE 802.11e interworking

Abstract

This article proposes a new architecture, which once implemented, would help in achieving end-to-end quality of service (QoS) requirements of an application which is being served in an interworking system of IEEE 802.16/WiMAX and IEEE 802.11e/WiFi networks. Our approach strives at mapping the QoS requirements of an application originating in IEEE 802.11e network to a serving IEEE 802.16 network and assuring the transfer of data having appropriate QoS back to the application in IEEE 802.11e network. We discuss how an application flow specifies its QoS requirements, either in an IEEE 802.11e or IEEE 802.16 network and the mechanisms that ensure that these requirements are known to the serving network. We identify the necessary parameters, as per advice in the standards, that could stipulate the QoS requirements for an application depending upon traffic type it represents. We propose the mapping of various parameters for different kinds of flows which would ultimately make sure that an application receives the QoS it requested. The resulting architecture would work as a hybrid of two different kinds of networks
