“…In a mixed grid based optical network, [21] proposed a service differentiation based spectrum defragmentation to solve the issue in flexible grid system. In [22], a novel heuristic method for lightpath routing and wavelength allocation was proposed, this heuristic algorithm is based on the concept of wardrop equilibrium that is to adaptively equalize the mean delay From these survey statements, there are two different objectives are considered in the WDM system to solve it for better data transmission system.…”

The data transmission system in the optical WDM network increases the speed of packet transmission by the wavelength of light beams . The Selection of the wavelength and the shortest path to transmit the packets form source to destination is a challenge in a large network architecture. To solve these two problems, the optimization model must handle both the objectives. In this paper we are proposing a novel multi-objective optimization algorithm to solve both the problem of wavelength allocation and shortest path identification in a WDM network. This can be achieved by the enhanced model of Multi-Objective Hunger Locust Optimization algorithm (MO-HLO). In this, it analyse traffic level in a network path and the availability of wavelength present at each time instant. The proposed system retrieves the parameters of network architecture and with the weight value of dynamic traffic occur in the routing path. Among these data, the optimization selects the best among overall feature set of the WDM arrangement. The MO-HLO algorithm extracts the combination of each attribute to form the cluster that segregates the routing path along with the traffic range. From the fitness of the objective function of MO-HLO, the best routing path and the availability of wavelength for a node can be analysed at each time instant.

Optical fibers are a key inventive discovery that contributed to the digital revolution, although cost becomes a major factor for long-distance communication. Whereas passive optical networks (PONs) offer reduced costs and cater to multiple users; hence, they are becoming more common in LANs, densely inhabited areas, and backbone networks. Numerous experiments on PON systems have been authored in the last couple of years, with results expressed in terms of BER, eye openings, quality of received bits factor, signal-to-noise ratio (SNR), and burst blocking, which demands a vast review of PONs based on these parameters. So, a comprehensive review of PONs is extensively researched to identify the methods’ limitations. Along with long-reach(LR)-PON systems, power conservation in PONs and burst contention are also addressed. To demonstrate the performance of PON architectures, the findings are provided in terms of delay, energy efficiency, and operations intensity.
