Colloquium, "Large-scale Multihop Wireless Networks: Applications and Research Challenges", Dr. Dmitri Perkins
Abstract
While wireless local area networks (e.g., WiFi) are common place today and capable of providing high-speed Internet access, a key disadvantage is its relatively short wireless coverage area, which typically ranges approximately 100-200 meters in diameter. In this talk, we introduce the broadband wireless mesh networking paradigm. Mesh networks combine the infrastructure-based features of WLAN technology with the self-organizing multi-hop routing principles of mobile ad hoc networking, to provide uninterrupted broadband access over large geographical regions. An ad hoc or mesh networking system is a distributed system of self-organizing computers or routing devices connected only by wireless links. The fundamental goal of mesh networking technology is to provide a means of wireless communication and networking with increased survivability, mobility, and ease of deployment relative to traditional infrastructure-based wireless systems such as existing cellular and wireless local area networks.
In this talk, we first motivate the use of mesh networks by introducing numerous applications that would benefit from such a system. Next, we discuss the significant research challenges facing mesh networks and introduce our ongoing research work in the area to address these challenges. We also provide an overview of CajunMesh, our on-campus experimental mesh testbed, which has the capacity to cover 10-30 acres and includes traditional 2.4 and 5 GHz WiFi technology as well as 700MHz WiFi technology.
