Catching Whales and Minnows using WiFiNet: Deconstructing Non-WiFi Interference using WiFi Hardware
Banerjee, Suman; Patro, Ashish; Rayanchu, Shravan (2012-03-28)We present WiFiNet --- a system to detect, localize, and quantify the interference impact of various non-WiFi interference sources on WiFi traffic using commodity WiFi hardware alone. While there are numerous specialized ... -
Diagnosing Wireless Packet Losses in 802.11: Separating Collision from Weak Signal
Rayanchu, Shravan; Mishra, Arunesh; Agrawal, Dheeraj; Saha, Sharad; Banerjee, Suman (University of Wisconsin-Madison Department of Computer Sciences, 2007)It is well known that a packet loss in 802.11 can happen either due to collision or an insufficiently strong signal. However, discerning the exact cause of a packet loss, once it occurs, is known to be quite difficult. In ... -
Loss-Aware Network Coding for Unicast Wireless Sessions: Design, Implementation and Performance Evaluation
Rayanchu, Shravan; Sen, Sayandeep; Wu, Jianming; Banerjee, Suman; Sengupta, Sudipta (University of Wisconsin-Madison Department of Computer Sciences, 2008)Local network coding is growing in prominence as a technique to facilitate greater capacity utilization in multi-hop wireless networks. A specific objective of such local network coding techniques has been to explicitly ... -
TRAC: An Architecture for Real-Time Dissemination of Vehicular Traffic Information
Rayanchu, Shravan; Agarwal, Sulabh; Mishra, Arunesh; Banerjee, Suman; Ganguly, Samrat (University of Wisconsin-Madison Department of Computer Sciences, 2007)Disseminating traffic related information to vehicular users is increasingly becoming a necessity nowadays in the context of Intelligent Transportation Systems (ITS). However, till date there does not exist an efficient ...
