Interactive WiFi Connectivity For Moving Vehicles
A. Balasubramanian, R. Mahajan, A. Venkataramani, B. N. Levine, J. Zahorjan, “Interactive WiFi Connectivity For Moving Vehicles”, ACM SIGCOMM Conference, (August 2008). [PDF] Summary Current WiFi handoff methods, where a client remains connected to a single basestation (BS), lead to frequent disruptions in connectivity in highly mobile vehicular networks. This paper proposes ViFi, a protocol ...

ExOR: Opportunistic Multi-Hop Routing for Wireless Networks
S. Biswas, R. Morris, “ExOR: Opportunistic Multi-Hop Routing for Wireless Networks,” ACM SIGCOMM Conference, (August 2005). [PDF] Summary ExOR is an integrated routing and MAC technique that opportunistically exploits the broadcast characteristics of the wireless environment. Unlike the traditional routing protocols, where the best sequence of nodes from a source to a destination is decided ...

Modeling Wireless Links for Transport Protocols
Andrei Gurtov, Sally Floyd, “Modeling Wireless Links for Transport Protocols,” ACM SIGCOMM Computer Communications Review, Volume 34, Number 2, (April 2004). [PDF] Summary Intrinsic characteristics of wireless links (e.g., variable bandwidth, bit corruption, channel allocation delays, and asymmetry) significantly affect performance of transport protocols. In addition, different types of wireless links show noticeable variance in ...
