delay-tolerant networking in restricted networks
For security reasons, many companies usually allow only strictly regulated communication, specific system configurations and predetermined software components. Therefore, often only communication over the HTTP protocol is possible, which operates by using a request-response approach. In this paper we present the design and evaluation of a convergence layer for our DTN implementation IBR-DTN using HTTP as underlying protocol. On the remote side we use a web server and a database for the connection management. Through the usage of long-polling we realize a bidirectional communication. In the evaluation, we show the results of bandwidth and latency measurements.
