Routing & QoS in heterogeneous tactical Networks

Approach:Technology-Aware MTR

Topologies represent link characteristicsApplications are mapped to topologies

OLSRv2 Military Extensions by Fraunhofer FKIE

Technology-Aware MTR Application data must match link characteristics

e.g. VHF not for high data rate applications

Interface selection independent of routing metric

Allows for the same routing metric for all topologiesHF-Link

SatcomUHF

Role Based MTR Medics do not forward tactical information

Decoupling of topology participation and forwarding

Medics can still receive tactical data while forwarding is prevented

Compatible withstandard OLSRv2 nodes

Security & Interoperability Routing dynamically establishes tunnels to direct neighbors

Tunnels are basis for Integration of MOTS Radios

Optional Security by IDP/MIKE integration per interface

Artillery Observer Scenario Planned EMCON

Reception of orders and information still vital for operation

Observers can have several proxies

Network topology can change as long as proxies stay in range
