“…The novelty of this algorithm lies in a path construction method based on tabu-table technique for formulating achievable paths commencing the source to every single receiver. [5] utilized the movement of the snake for cost matrix formulation so as to optimize the optical network. Pavani, et al [22] Analyzed the uncertain problems in the implementation of ACO algorithms in optical networks in three categories of byzantine failure such like misdirection of onward ants, plummeting of forward ants and plummeting of backward ants.…”

In this paper, a new Fault detection and network survivability method is presented based on Enhanced particle swarm optimization (PSO) technique intended for the optical networks. The Heuristic H-PSO algorithm developed from particle Swarm optimization, and it is used for locating the failures position through finding the fitness value of the aforementioned links. The greedy algorithm is used for wavelength assignment. The novelty of this work exists in the form of fitness function that uses bandwidth availability and packet delay as a parameter metrics that ensures the quality of the link paths. As a result, it determines the non-functioned links and the components. This algorithm gives interesting results that verify the logical optics topology that requires to be sustained over the physical network despite of great traffic tenseness. The proposed algorithm is validated considering practical tests with the use of Network Simulator (NS) -2 by patching OBS in Mesh topology. Results obtained through this optimization model shows promising and superior result with respect to Blocking Probability, End to End delay, Throughput and Burst Loss Rate. Numerical Result shows that there is a decrease in Blocking Probability, End to End delay and Burst Loss Rate in turn shows predominant increase in Throughput compared to E-OBS, E-BSL and E-BSL D methods.
