Abstract

Maintainability and context awareness knowledge increase the requirement of cross-layer architecture. The wealth of cross-layer coordination examples from miscellaneous fields of networking are security, handoff, autonomic communication, routing, sensor networks, quality of service and energy. In the cognitive radio, selection of suitable wireless channels in the vicinity depends on application requirements and network conditions. Different static and dynamic cross-layer optimization heuristics are available in literature with different performance parameters. The paper discusses different cross-layer architecture and link optimization for improving the performance of network. The prime focus is on link prediction methodology for enhancement of the performance of network. Various performance parameters of protocols of software defined networks are compared. Throughput, end-to-end delay, jitter, PDR and goodput with different scenarios are observed and compared. It is observed that the performance of OLSR is better in different scenarios as compared to other protocols.


Description

Interaction within adjacent layers is strictly limited in OSI reference layered model and applications are only allowed to use APIs provided by OS, whereas cross-layer design provides flexibility of communication within any protocol layers and system component including applications. Cross-layer design enhances the performance of wireless communication by providing the ability to share information across all layers. Based on the wireless network conditions, automatic (de)activation at run time makes its ability hard to add, remove and modify cross-layer coordination heuristics. A cross-layer coordination algorithm is hard-wired, realized at compile time and is deeply embedded within the operating system, i.e., energy-saving cross-layer coordination algorithm.
