Villagenet: A low-cost, 802.11-based mesh network for rural regions (2007)

Partha Dutta, Sharad Jaiswal, Debmalya Panigrahi

Abstract — VillageNet is a wireless mesh network that aims to provide low-cost broadband Internet access for rural regions. The cost of building the network is kept low by using off-the-shelf IEEE...

Formal analysis of passive measurement inference techniques (2006)

Sharad Jaiswal, Gianluca Iannaccone, Jim Kurose, Don Towsley

Abstract — Verifying the accuracy of a passive measurementsbased inference technique under all possible network scenarios is a difficult challenge- the measurement point has limited observability...

Identifying 802.11 traffic from passive measurements using iterative Bayesian inference (2006)

Wei Wei, Sharad Jaiswal, Jim Kurose, Don Towsley

In this paper, we propose a classification scheme to differentiate Ethernet and WLAN TCP flows based on mea-surements collected passively at the edge of a large network. This classifier computes the...
