The paper describes an Energy — Efficient Resource Allocation protocol for Wavelength-Routed All-Optical WDM Networks. Protocol selects efficient and low power consumption optimal primary and backup paths. The path selection will be done by Central Management System (CMS). The selection will be by two methods, i.e., the path with less number of free wavelengths will not be considered for selection...
Existing methodologies in WDM networks, generally uses either lightpath distance or network congestion to identify optimal and backup lightpaths. In our paper, we have designed an efficient alternate RWA protocol (EARP) which considers both congestion and route distance so as to improve the network performance. On arrival of a request the source node sends control signals through all the paths to...
