Abstract:
As the Internet utilizes more wireless technology, we witness more and more mobile and opportunistic network applications. Protocol design for such a network has become more challenging. This discussion starts with a quick overview of the challenges and solutions for routing in dynamic networks, including protocol design, having knowledge of certain information, and mobility models. We then focus on two algorithmic graph models, based on two contact models, that capture both time and space: discrete contact and probabilistic contact models. We show how the traditional Dijkstra’s shortest path and Bellman-Ford algorithms can be extended to solve two specific routing problems under these two contact graph models. This talk ends with a discussion about some future challenges of network design with a focus on the integration of other related fields.
