Ad Hoc Mobile Wireless Networking

Faculty: Steve Lai http://www.cse.ohio-state.edu/~lai/  IEEE 802.11 is the most widely deployed standard for wireless LANs. We are interested in its scalability issue, i.e., we are aiming to answer the question: “Can they support large-scale, multi-hop ad hoc networks?”  Particularly, we are working on the following topics: o o o o o Is IEEE 802.11 scalable? Time sync in multihop ad hoc networks Is time sync essential for power saving?
