With the development of various radio communication systems in recent years, spectrum sharing in heterogeneous networks has received a considerable amount of research attention for the efficient use of spectral resources, as the lack of these has emerged as an important problem. Prevalent spectral sharing methods focus on improving total throughput, and ignore lower throughput along the cell edges...
In recent years, the number of requests to transfer large files via large high-speed computer networks has been increasing rapidly. Typically, these requests are handled in the “best effort” manner and resulting in unpredictable completion times. In this paper, we consider a model where a transfer request either must be completed by a user-specified deadline or must be rejected if its deadline cannot...
To deal with exponential traffic growth, Elastic Optical Networks (EONs) are necessary because they enable to provide large capacity transmissions. In EONs, multiple widths of spectra are assigned to optical paths. Therefore, fragmentation in frequency domain degrades network performance. We propose a spectrum allocation method to reduce blocking probability and node costs, especially in spatially...
We propose novel optical node architecture based on the Architecture on Demand concept with sophisticated spectrum and core allocation in Multi-Core Fiber Elastic Optical Networks. More than 85% of flexible spectrum selective switches can be reduced by replacing fixed-grid MUXs/DEMUXs.
Wireless sensor networks have been studied for several applications. Disaster damage monitoring is one of the significant applications in sensor networks. If sensors are set up in buildings or on water pipelines, they could detect damage, victims trapped beneath rubble, or water leakage in case of a natural disaster. Since such a monitoring system is required to operate for a long term (e.g. several...
