Delay Tolerant Networks, Disconnect Data Distribution, WiFi-Direct


The world today is highly connected and there is an immense dependency on this connectivity to accomplish basic everyday tasks. However much of the world lacks connectivity. Even in well-connected locations, natural disasters can cause infrastructure disruption. To combat these situations, Delay Tolerant Networks

(DTNs) employ to store and forward techniques along with intermittently connected transports to provide data connectivity. DTNs focus on intermittently connected networks however what if the regions are never connected? For example, Region A - is never connected to the internet, and Region B – has internet connectivity. Using a vehicle that travels between the two regions it is possible to transport the data from A to B and vice versa. Current vehicular-based DTN approaches make use of dedicated hardware infrastructures mounted on vehicles. Our research focuses to shift all this computing to personal smartphone devices. The users in disconnected areas will install the Disconnect Data Distribution(DDD Android application on their phones. This application will receive data from various applications on their phone via inter-process communication(IPC) and package the data into bundles using a DDD library. Vendors, transportation operators, delivery people, and others that regularly travel between connected and dis-connected areas can download the Bundle Transport Application on their Android phones. These devices will then communicate with each other using short-range wireless technology like WiFi-Direct in the disconnected region. The device on the transport can communicate with the Servers over the internet. For this project, we should assume that the Client and Server can provide data as desired and our focus is on the Transport.
