Integrating Passive Optical Network (PON) and Worldwide Interoperability for Microwave Access network (WiMAX)achieves universal internet connectivity at a higher data rate. Here Passive Optical Networks (PONs) are used as the backbone. Base stations in WiMAX are connected to Optical Network Units. In this work cost, routing and resource allocation related issues in hybrid networks are investigated. Light trails are used for traffic grooming. Various network topologies are used for simulation and results are obtained, compared. and analyzed. The results confirm a lower cost solution by using hybrid networks for universal connectivity.

In this paper, we summarize the contributions of the Doctoral Thesis entitled Protection in Elastic Optical Networks with Spatial Multiplexing. This thesis proposes solutions for protection of elastic optical networks with spatial multiplexing, aiming at reducing the blocking of requests and the improvement of resource utilization. For this, we take into account the use of different schemes to paths protection, adaptive modulation, traffic grooming, spectrum overlap in protection paths, minimum interference routing and multipath routing. The algorithms proposed will allow the provisioning of protection in optical networks that will transport much greater volumes of traffic than do the current networks.
