Network hierarchy makes network protocols more scalable and robust, but also makes the network more complex and reduces performance. With routing protocols, hierarchy reduces overhead, routing table size, and convergence time, but can also cause sub-optimality (stretch) of the routing path length compared to the flat networks. With OSPF, for example, adding(More)
This paper presents the work that is currently performed in the E-SPONDER (FP7-242411) project. E-SPONDER is a suite of real-time data-centric technologies which will provide actionable information and communication support to first responders that act during normal and abnormal events (crises). This information will enable improved control and management,(More)
