QoS facets of cross layer asserted wireless frameworks: A survey

Wireless network is based on packet switching concept and is capable of handling various types of applications. The challenge is to attain a better Quality of Service (QoS) for the like applications of real time and non-real time in an intriguing environment with varying bit rate, unexpected channel lay off. The intention of QoS provision is to afford the opted services for the users while utilizing a particular application. A cross layer approach is particularly important for any network using wireless technologies, since the state of the physical medium can significantly vary over time. This survey paper presents various wireless technologies and its frameworks in QoS perspective.
