CAREER: Accessing Shared Objects and Routing in Distributed Environments

点击翻译按钮获取中文摘要

The research component of this project focuses on two fundamentaldistributed network problems. The first problem is that of devisingan efficient method for accessing shared information (objects) in adistributed scenario (Problem A); the second problem is probably themost fundamental problem that arises in any communication network,namely that of devising efficient point-to-point routing protocols(Problem B).More specifically, the PI proposes to accomplish the followingresearch items:- to deliver solutions to Problem A in fixed-connection networks, taking into account several important network parameters -- such as link congestion, dynamic link costs, and multiple representations of objects -- and in cellular and ad-hoc wireless mobile scenarios.- to deliver solutions to Problem B in conjunction with Problem A, with the aim of minimizing the cost of accessing an object.- to deliver solutions to Problem B on its own, in wireless mobile and fixed-connection scenarios. Not surprisingly, the problem of accessing shared objects and therouting problem in distributed environments are strongly related inmany ways. For example, they are directly related in dynamicscenarios. Therefore the PI anticipates that studying these twoproblems together in mobile scenarios will help devise bettersolutions for both problems.
