a novel delay aware Routing Algorithm dara for a hybrid wireless optical broadband access network woban
IEEE Network, 2008Co-Authors: S Sarkar, Honghsu Yen, Sudhir Dixit, Biswanath MukherjeeAbstract:A hybrid wireless-optical broadband access network (WOBAN) is a promising architecture for future access networks. Recently, the WOBAN has been gaining increasing attention, and early versions are being deployed as municipal access solutions. This architecture saves on network deployment cost because fiber need not penetrate to each end user. However, a major research opportunity exists in developing an efficient Routing Algorithm for the wireless front-end of the WOBAN. We propose and investigate the characteristics of the delay-aware Routing Algorithm (DARA) that minimizes the average packet delay in the wireless front-end of a WOBAN. In DARA we model wireless routers as queues and predict wireless link states periodically. Our performance studies show that DARA achieves less delay and congestion, and improved load balancing compared to traditional approaches such as the minimum-hop Routing Algorithm, shortest-path Routing Algorithm, and predictive throughput Routing Algorithm.

dara delay aware Routing Algorithm in a hybrid wireless optical broadband access network woban
International Conference on Communications, 2007Co-Authors: S Sarkar, Honghsu Yen, Sudhir Dixit, Biswanath MukherjeeAbstract:Hybrid wireless-optical broadband access network (WOBAN) is a promising architecture for future network operations. Recently, the wireless part of WOBAN has been gaining increasing attention and early versions are being deployed as a municipal access solution to eliminate the wired backhaul to every wireless router. This architecture saves on network deployment costs because fiber (or wiring) does not need to extend to the end user, and it extends the reach of emerging optical access solutions, e.g., passive optical network (PON)-based access solutions. However, a major research opportunity exists in developing an efficient Routing Algorithm for the wireless front end of WOBAN. We propose and investigate the characteristics of "delay- aware Routing Algorithm (DARA)" that minimizes the average packet delay in the wireless front end of a WOBAN. We model wireless routers as queues and predict wireless link states periodically. Our simulation experiments show that DARA achieves better load balancing and less congestion compared to tradional approaches such as minimum-hop Routing Algorithm (MHRA) and shortest- path Routing Algorithm (SPRA). In addition to minimizing the delay, DARA also improves the average hop count compared to the predictive throughput Routing Algorithm (PTRA), a popular protocol used in several deployments for the wireless front end of a WOBAN.

an adaptive fault tolerant Routing Algorithm for hypercube multicomputers
IEEE Transactions on Parallel and Distributed Systems, 1995Co-Authors: Y LanAbstract:This paper presents a partially adaptive fault-tolerant Routing Algorithm for hypercube multicomputers. The Algorithm is tolerant to n-1 link and/or node faults for an n-cube. It makes Routing decisions adaptively based on local failure information only. It is simple to implement and needs a very small message overhead. A comparison between the Algorithm and a popular previous work is given.

qpso based qos multicast Routing Algorithm
Lecture Notes in Computer Science, 2006Co-Authors: Jun Sun, Jing LiuAbstract:QoS multicast Routing in networks is a very important research issues in the areas of networks and distributed systems. Because of its NP-completeness, many heuristics such as Genetic Algorithms (GAs) are employ solve the QoS Routing problem. Base on the previously proposed Quantum-behaved Particle Swarm Optimization (QPSO), this paper proposes a QPSO-based QoS multicast Routing Algorithm. The proposed method converts the QoS multicast Routing problem into an integer programming problem and then solve the problem by QPSO. We test QPSO-base Routing Algorithm on a network model. For performance comparison, we also test Particle Swarm Optimization (PSO) Algorithm and GA. The experiment results show the availability and efficiency of QPSO on the problem and its superiority to PSO and GA.
