ENERGY AWARE DISTRIBUTED PARTITIONING DETECTION AND CONNECTIVITY RESTORATION ALGORITHM IN WIRELESS SENSOR NETWORKS
Mobile sensor networks rely heavily on inter-sensor connectivity for collection of data. Nodes in these networks monitor different regions of an area of interest and collectively present a global overview of some monitored activities or phenomena. A failure of a sensor leads to loss of connectivity and may cause partitioning of the network into disjoint segments. A number of approaches have be...
متن کاملDynamic routing in translucent WDM optical networks
Translucent WDM optical networks use sparse placement of regenerators to overcome the impairments and wavelength contention introduced by fully transparent networks, and achieve a performance close to fully opaque networks with much less cost. Our previous study proved the feasibility of translucent networks using sparse regeneration technique. We addressed the placement of regenerators based o...
متن کاملPath Protection in Translucent WDM Optical Networks
Translucent WDM networks are receiving attention as longhaul back bone networks. One important aspect of such networks that has not received attention is the possibility of cycles in the path of a translucent network. This is the first work on implementing path protection in translucent networks, considering the possibility of cycles. Two formulations have been proposed here for dynamic lightpa...
متن کاملTranslucent optical WDM networks for the next-generation backbone networks
This paper proposes an alternate approach to fully transparent and fully opaque optical networks for operating a wavelength routed optical network. In this paper, the architecture of the regeneration node that performs sparse regeneration (or translucency) is discussed. The regeneration demands generated from call blocking and signal quality requirements are addressed. Two implementation strate...
متن کاملRestoration Design in IP over Reconfigurable All-Optical Networks
Large IP backbone networks today are mostly deployed directly over sequences of point-to-point DWDM systems or chains of newer ROADM-based ultra long haul systems, interconnected by OEO regenerators. The next generation core optical network is moving toward an all-optical network architecture that is based on multi-degree ROADMs to reduce OEO regeneration cost as well as enabling automatic reco...
