Background

Tactical (edge) networks are characterized by their heterogeneity in networking and radio technologies, their high network dynamics and their limited bandwidth, posing challenges to efficient communications especially in larger coalition settings. In particular, enabling group communications in the (coalition) heterogeneous tactical environment still poses a major challenge. E.g. existing routing strategies show limitations in terms of scalability and efficiency which is especially costly when running group services between soldiers in the field. This TAP will focus on research to explore generic tactical (edge) network infrastructure and protocols that supports group services. IST-124/RTG-061 has studied different ways to build heterogeneous networks in a mobile military environment primarily with the IP network architecture as a baseline. The group concluded that there is still much more research that is needed to build flexible, reliable, and resilient networks in this challenging environment and wants to keep focus on this area. This proposal suggests studying solutions for heterogeneous networking within (e.g., IP multicast) as well as outside of the traditional IP architecture (i.e., Information Centric Networking (ICN)) with a major focus on supporting efficient group communications in this environment. Both connectivity, QoS, and efficient data dissemination are of interest. The activity will continue developing and utilizing the emulation testbed environment that was developed by the IST-124 group to facilitate efficient research collaboration for heterogeneous network research and might do a collaborative experiment at CWIX to evaluate promising approaches.

Objectives

• Contribute to the improved understanding of important tradeoffs when establishing mobile military heterogeneous networks at the mobile tactical edge to support group (data and communication) services: o Gain more insight in how to achieve more reliable and predictable network and (group) service performance o Gain more insight in how different approaches to efficient data dissemination compare to each other, including disruptive technologies (e.g, ICN approaches such as CCN and NDN) o Investigate possible enhancements to networking technologies for group communications (i.e. IP multicast, ICN) o Investigate how group services and unicast services can coexist on the same tactical infrastructure • Further develop the emulation testbed and collaborate on experiments and demonstrations of architectures and mechanisms on the emulation testbed

Topics

• Solutions for group communication in a mobile heterogeneous network environment o Traditional multicast and flooding protocols o Combination of IP multicast protocols and embedded solutions (e.g., cooperative broadcast) o ICN architectures for group communication (e.g. NDN and CCN) o Data dissemination protocols/frameworks o Interaction of multicast protocols with application driven dissemination strategies o QoS and Resource management for group communication • Efficient coexistence of point to point/unicast communication and group communication • Emulation testbed environment (Anglova scenario from IST-124) o Prepare the emulation environment for group communication experiments o Continue developing and improving emulation of the Anglova scenario
