MobileInsight: Analyzing Cellular Network Information on Smartphones.

MobileInsight is a software tool that collects, analyzes and exploits runtime, fine-grained cellular network information over commodity phones. It is our first step to help developers and researchers understand the closed, large-scale cellular network system. It exposes the below-IP protocol messages to the user space, provides protocol analysis, and offers APIs for mobile applications to obtain low-level network information. We have built showcases to illustrate how MobileInsight can be applied to cellular network research.
