Title: Multi-Hop Wireless Networking: Issues and Opportunities
Speaker: Dr. Yuanzhu Chen, Associate Professor, Department of Computer Science, Memorial University.
Abstract:
A multi-hop wireless network is a wireless communication network, where nodes that are not within direct transmission range of each other will require other nodes to forward data. It can operate without existing infrastructure, supports mobile users, and sometimes take the form of mobile ad hoc networks, wireless sensor networks, delay-tolerant networks, and so forth. Such a networking paradigm originated from the needs in battlefield communications, emergence operations, search and rescue, and disaster relief operations. Later, it found civilian applications such as community networks. Compared to the TCP/IP based Internet, such a networking paradigm has a number of salient features, such as broadcast medium, fast network topology change, and frequent and extended disruption. In this talk, I will present some of our research projects to address the issues inherent to this networking technology in an effort to advance the state of the art of the area.
