Hop-by-Hop Congestion Control Over a Wireless Multi-Hop Network [PDF]

open access: yesIEEE/ACM Transactions on Networking, 2005
This paper focuses on congestion control over multi-hop, wireless networks. In a wireless network, an important constraint that arises is that due to the MAC (media access control) layer. Many wireless MACs use a time-division strategy for channel access, where, at any point in space, the physical channel can be accessed by a single user at each ...

Spatial Transportation Networks with Transfer Costs: Asymptotic Optimality of Hub and Spoke Models [PDF]

open access: yes, 2007
Consider networks on $n$ vertices at average density 1 per unit area. We seek a network that minimizes total length subject to some constraint on journey times, averaged over source-destination pairs. Suppose journey times depend on both route-length and
