Critical analysis of Cross-layer approach

Internet has become everyday utility. Internet is ubiquitous. All the devices including household devices are connected to the Internet. Layer approach is used for the design of Internet. Layered approach is robust but is designed for wired networks. Cross-layer approach is examined extensively in mobile networks because of the layered approach inability to provide the required performance. There are many tradeoffs associated with the use of Cross-layer approach. It breaches the basic principles of layered approach and may compromise the robust nature of the Internet. But with wide use of multimedia applications and mobile devices, we cannot continue to use layered approach as it is. In this paper justification the role of Cross-layer approach is presented, and critical analysis of it is done to identify its limitations.
