Through the study of MANET's QoS multicast routing problem, we propose a heuristic-demand multicast routing algorithm. Algorithm combines the MANET network bandwidth estimation algorithm, redefined the select function, restrictions request packets of flooding algorithm, to ensure fair treatment delay and bandwidth. Simulation results show that the algorithm has the advantage of fewer routing overhead, high success rate.
Results of modeling of the signal passing through equivalent circuits with the time-varying parameter are given in this paper. Parameters of such circuits correspond to the reflection coefficient, which is necessary for modulation of the backscattered signal in the tag-to-reader line. The main idea of this research is developing a general description of conditioning of digitally modulated signals backscattered from a tag to a reader.
