Cross-Layer Architectures for Autonomic Communications

Abstract: Abstract. Layered architectures are not sufficiently flexible to cope with the dynamics of wireless-dominated next-generation communications. Most existing architectures and approaches depend purely on local information and provide only poor and inaccurate information gathering at the global scale. De-layered or crosslayer architectures may provide a better solution: cross-layering allows interactions between two or more non-adjacent layers in the protocol stack. We propose a new cross-layer architecture which… Show more

“…The one dimensional layered model has been used successfully for many years and still forms the basic framework for the current Internet. However, in addition to being inadequate for meeting the requirements of multiservice traffic, in particular for real time applications, they are now also being seen as inadequate for coping with the dynamics of TCP/IP based wireless communication and the requirements of autonomic communication (Razzaque 2007). The cross-layer approach has been proposed as a solution to the interaction and exchange of information between non-adjacent layers and is seen by some as an implementation optimization that leads away from the strictly layered approach.…”

“…Cross-layer design breaks away from traditional network design. In traditional network design, each layer of the protocol stack operates independently and information is exchanged only between adjacent layers of the protocol stack [5] as shown in Fig. 4.…”

“…However, from the mobile and wireless networking perspective, uncertainties of the wireless medium pose stiff challenges to the seamless functionality of ubiquitous services and applications and appears in various facets in all layers of the traditional protocol stack [10]. Therefore, crosslayer radio resource management (RRM) approaches, which assume that any kind of information (including context) has to be exchanged between different layers of the traditional protocol stack, have to be adopted so as end-to-end performance can be optimized by adapting each layer against this information [11]. Moreover, given the fact that next generation wireless networks' reality conglomerates many heterogeneous networking systems, cross-system rationale helped in defining ways to exchange uncertain contextual information among heterogeneous entities residing in different systems, following the same rationale points as in cross-layering regarding overall optimal system performance.…”
