For physical-layer security, key reconciliation procedures are needed to correct key differences that can arise as a consequence of independent noise at the two ends of a reciprocal link. We assume either a random link in a mobile environment or use reconfigurable antenna elements to randomize the channel, such that it allows for frequent key generation. We(More)
Recently, Li and Pan proposed a deterministic network coding resource optimization method built to overcome the issue of severe performance degradation of network coding in the presence of erasures. Considering a multicast scenario, their method relied on the use of Ant Colony Optimization (ACO) to find shortest disjoint paths from a source to each sink and(More)
Starting from a recently proposed network coding resource optimization method, we discuss the scalability of this solution to larger scale-free topologies that are also characterized by a realistic link loss distribution which we derive from measurements. We sketch a possibility of designing a network coding aware multicast routing scheme for hierarchical(More)
