Capacity Scaling in Mobile Wireless Ad Hoc Network with Infrastructure Support
The authors study the throughput capacity of mobile wireless ad hoc networks with infrastructure support. Mobility and infrastructure support independently have been shown to be effective ways to improve capacity, but few work has analyzed the impact of their combination. In their work, they consider an ad hoc network with n users and k base stations. All base stations are wired to each other with bandwidth c(n). Wireless ad hoc networks are modeled as a set of n nodes that exchanges messages using radio transmissions. A well-known challenge in these networks is the poor scalability of throughput capacity, i.e., the maximal traffic rate that can be sustained as n grows.
