| Research Abstract |
(1) Design Evaluation of Web Pages in E-commerce Sites
We have proposed a Markov chain model for the process of reaching the target page by successively selecting the links on the web pages in an e-commerce site. Our model has been applied to the evaluation of the ticket reservation web sites of three airline companies.
(2) Modeling and Design of Cellular Mobile Communication Networks
We have proposed a renewal process model to evaluate the number of cell crossings during each session in a cellular mobile communication network. Our model has been used to design the optimal dynamic mobility management for terminal locations.
(3) Routing and Wavelength Assignment for Large-Scale WDM Optical Networks
We have proposed two fast routing and wavelength assignment algorithms for large-scale wavelength-division-multiplexing optical networks where each transmission request is served by an all-optical lightpath without wavelength conversion.
