Abstract:

An overlay multicasting solution which combine a selected lightweight traditional multicasting routing algorithm and the related constrained model used to integrate multi-constraints is proposed. Based on the guidance above, a degree and quality of service related constrained fast lightweight multicasting routing algorithm is proposed. After analyzing the children-detect-and-father-response mechanism using both active and passive detections, the maintenance and control overhead is further reduced to deal with the node failure and the dynamic performance optimization, so a fast and lightweight multicasting protocol is achieved. Simulation for the multicasting routing algorithm proves the proposed.
