QoI in DTN-based directional networks

Due to high traffic demands, networks are increasingly required to implement techniques which support prioritization. Internet quality of service (QoS) approaches such as differentiated services (Diffserv) and Integrated Services (Intserv) can function in a traditional provider network. However, in some domains these techniques are not straightforward to implement. Wireless networks are increasingly using directional networking capabilities to handle increased traffic demands. However, prioritization techniques for such networks are in the research phase. In this paper we propose an approach to prioritize traffic in these types of networks using the principles of quality of information (QoI). We build on previous work which established topology control and routing approaches for directional networks using delay/disruption-tolerant networking (DTN). We extend this framework to support varied information quality.
