Connected Crossroad is an Android application that utilizes Google's Nearby Connections API to implement Ad Hoc On-Demand Distance Vector (AODV) routing to establish a Mobile Ad Hoc Network (MANET). The application can also integrate non-Android devices into the MANET via UDP.

This application must run on a physical Android device, as it uses networking features which cannot be emulated. Once the application has started the user must input an "address" for the device, which must be a number. After the user clicks the button to set the address, the discovery process of the routing protocol is initiated. The user can then send a message to another device in the network by inputting the address of the device to send to and the message to transfer, and then clicking the send message button. It is useful to view the application logs in Logcat to understand what the app is doing.

Details about the AODV routing algorithm can be found in RFC 3561.

An example of another AODV application that targeted a non-Android device, but connected with Androids in this application via UDP is AODV.

This application is in active development at the University of Virginia as part of the "Exploring Mobile Ad Hoc Networks (MANETs) to Enable Connected Transportation Services" research being conducted in Dr. Haiying Shen's Pervasive Communications Laboratory.
