P. Angu & Ramamurthy, B. (2010), "Continuous and Parallel Optimization of Dynamic Bandwidth Scheduling for WDM Networks", In GLOBECOM '10. IEEE Global Telecommunications Conference. December 2010.

[Abstract] [BibTeX]

Abstract: Many scientific and Grid applications require high-speed circuits of guaranteed bandwidth for scheduled transfers. Offline optimization of dynamic scheduled bandwidth demands is an efficient way of finding the near-optimal solution to the bandwidth scheduling problem. In this paper, we propose a continuous and parallel optimization method to address the dynamic and deterministic bandwidth scheduling problem in next generation wavelength-division multiplexing (WDM) networks. In this method a greedy algorithm and genetic algorithm are run in parallel in separate threads and both of them take the Dynamic Scheduled Bandwidth Demand (D-SBD) as their input. The user gets his response only from the greedy algorithm and hence he will get a deterministic answer in a short amount of time. The genetic algorithm takes as one of its inputs the output of the greedy algorithm and does the optimization of the D-SBDs with minimizing blocking probability as its fitness function. The greedy algorithm copies the optimized reservation database of the genetic algorithm at regular intervals. The user submitting a D-SBD request is unaware of the optimization done by the genetic algorithm. This method is evaluated using both trace driven simulation of real network traffic from the DOE ESnet network and stochastic traffic in ESnet network topology and a 24 node network topology. We also compare our approach with an earlier proposed method called re-optimization at blocking. Adding the genetic algorithm improves the performance of the network (in terms of blocking probability) compared to using only the greedy approach or the re-optimization at blocking method.

[Abstract] [BibTeX]

Abstract: Advanced distributed applications in engineering, scientific and

business domains that are highly data-intensive demand

high-performance computing platforms. Grid networks based on optical

technology provide a promising approach to create efficient

infrastructure to support such applications. These networks, termed in

general as Lambda Grid networks, are based on optical circuit

switching and employ wavelength division multiplexing and optical

lightpaths. In this paper, we propose an approach based on Tabu Search

heuristic for joint scheduling of computing, network and storage

resources in a Lambda Grid network. The objectives are to minimize

cost by efficient usage of resources and to minimize total completion

time of job execution. The results are compared to a Greedy

approach. Simulation results from both the methods show that the Tabu

search heuristic performed better than the greedy approach in

optimizing both the cost and completion time objectives.

[Abstract] [BibTeX]

Abstract: In this paper, we describe the design, implementation and deployment details of a two-tier real-time environmental monitoring network in Nebraska. Our state-wide sensor network infrastructure uses typical Wireless Sensor Network (WSN) structure at tier-two to conduct dynamic sensing tasks with high resolution and flexibility. The satellite communication technology is used at tier-one to provide reliable and low-cost long-haul connectivity between each local WSN and the central base station. By the end of 2009, the entire tier-one infrastructure has been designed and deployed to provide state-wide wireless connectivity for 54 monitoring sites equipped with 1-4 water level transducers. A data and network management framework has also been developed to enable the remote network re-tasking and network performance analysis from a central base station. The network web portal offers integrated real-time and historical groundwater data to worldwide users. The deployed infrastructure will serve as the prototype network to expedite the commercial adoption of large-scale WSN design for long-term environmental monitoring applications.
