Investigation of QoS Multicast Routing Based on Intelligent Multiple Constrained

Firas Mahdi Muhsin Al-Salbi


With the rapid development of Internet, mobile networks and high-performance networking technology, quality-of-service (QoS) of multicast routing has become a very important research issue in the areas of networks and distributed systems. This paper introduces quality of services multicast routing by using intelligent Algorithm. Its main objective is to construct a multicast tree that optimizes a multi objective function with respect to performance-related constraints (Short path, delay, packet loss). The proposed algorithm can be divided in two steps. First step, multicast tree selection algorithm based on shortest path.  Second step, to find routes with two or more QoS parameters is a hard problem. Therefore, it will divide in two parts according to the customer service. Part one; optimize QoS Based on delay minimization and packet loss. Part two; optimize QoS Based on cost minimization and packet loss. The simulation results show that the proposed algorithm is effective approach to multicast routing decision with multiple QoS constrains for mobile ad-hoc networks.
