In this paper, we have proposed a Multiservice Provisioning Optical Code Switching (OCS) method for GMPLS networks, which uses Optical-Code-Division-Multiplexing (OCDM) across every lightpath of a wavelength division multiplexing system. We also presented the router architecture for the GMPLS multiservice network. In this method, the Multi Length Variable Weight Optical Orthogonal Code (MLVW-OOC) is used to multiplex each class (two-class system) service connection to a wavelength as an OCDM signature series. First, the fiber bandwidth has been classified into several wavebands, whose wavelengths are considered for a specific service class depending on the characteristics of that service class. The codes corresponding to the service class are also given in this manuscript. Erlang's traffic behavior of the network model is used to evaluate the system performance as well as to obtain the probability density functions (PDF) of the number of labels oocupied by a link. We have also evaluated the PDF for the number of labels occupied in each wavelength. Further, we have evaluated the performance of the network in terms of the probability of outage, blocking probability, and the end-to-end (EE) bit error rate (BER) of a connection. The results indicate that interfering users perform better with longer-weight code words. Moreover, with the increase in the number of intermediate OCS routers, EE BER is increased, and it is found that by constraining the number of connected paths, performance can be improved.

A large number of RSUs are deployed to improve vehicular ad-hoc networks (VANETs) in recent years. On the other hand, it leads to an increase in the cost of the network. Multi-hop cooperative data dissemination (MHCDD) protocols can reduce using RSUs. These RSUs must cope with intermittent connectivity for longer distance communication. Minimizing the RSUs increases the data traffic and end-to-end delay. Moreover, mobility management, handling the connection time between vehicles, and data traffic in VANETs are challenging tasks in dense networks. In this context, we proposed a multi-hop cooperative data dissemination technique using a virtual network functioning and software-defined network-enable on the heterogeneous vehicular network (SDHVN). The problem of packet scheduling on the buffer occupancy is solved using an enhanced periodic update (ePU) and enhancing event-driven deadline (eEDD). The results illustrate the proposed algorithm's significant performance in terms of availability with the limited wireless channels. The queueing models adopted for optimizing the load balancing are by using the mobile edge controller. These queueing model minimizes the latency and maximizes network utility. [ABSTRACT FROM AUTHOR]
