In this paper, we investigate the energy-efficient grooming with distance-adaptive load balancing (EEG-DALB) in flexible bandwidth optical networks. For comparison, an existing energy-efficient approach without grooming and load balancing (EEA-WGLB) is also introduced. Simulation results show that the proposed EEG-DALB achieves better performance in terms of the blocking probability and average power...
In this paper, we propose a distance-adaptive load balancing algorithm to improve spectrum efficiency and to reduce power consumption in flexible bandwidth optical networks. Simulation results show that our proposed DALB algorithm significantly reduces blocking probability but consumes more power consumption compared to the traditional Dijkstra algorithm under the 40 Gbps, 100 Gbps, and mixed line...
In this paper, we present a novel cross-stratum resources integration (CSRI) architecture in fog-computing-based radio over fiber networks (F-RoFN) for 5G services. Additionally, a cross-stratum optimization (CSO) scheme is introduced in the proposed architecture. The CSRI architecture with CSO scheme can effectively pull the remote processing resource locally to implement the cooperative radio resource...

This paper proposes a flexible intelligence cloud-based radio over optical fiber networks by designing and using a reconfigurable wavelength-frequency selective switch. Numerical results demonstrate the feasibility of the proposed architecture and excellent spectrum effectiveness.
In this paper, we investigate tradeoff between failure probability and load balancing in flexible bandwidth optical networks. We develop a tradeoff-principle algorithm (TPA) to improve spectrum efficiency and introduce a traditional algorithm (TA) for comparison. Simulation results show that TPA achieves better performance compared to TA.

This paper proposes multi-dimensional resource mapping algorithms for inter-datacenter optical networks. Simulation results show that these proposed mapping algorithms can achieve better performance in blocking probability and revenue-to-cost ratio than the baseline algorithm.
A bent-tip optical angular displacement sensor was designed. The output function of the bent-tip fiber gained based on the bent-tip optical bundle structure analyzing. Effects of spacing p and angular α on receiving optical fiber bundle and the transmitting fiber was simulated, and the displacement h of transmitting fiber from reflect surface impact on the differential intensity is investigated. Sensor...

With the growth of cloud computing and other high-bitrate disaster recovery center (DRC) support service, DRC networks play an important role in the future networks. But the nature or man-made disaster is the main threaten of survivability. In this paper, we focus on the protection of DRC node based on contentconnectivity against disaster in disaster recovery center networks. An integer linear programming...
In this paper, compared with the previous works about software defined network (SDN), software defined optical network (SDON) has the advantages of less delay and higher transmission rate.

Different multicasting schemes and their performance in the Optical Packet Switched networks are investigated in this paper. Computer simulation results show that compared with the parallel-mode and serial-mode multicasting schemes, hybrid-mode multicasting scheme is the best way to deliver multicast sessions in the OPS networks due to its highest performance.
