QoS Multicast Routing Algorithm over Hybrid Hap-Satellite Networks

چکیده
Emerging network applications require the delivery of packets from one or more senders to a group of receivers. For this reason QoS Multicast Routing Algorithm is a key problem for the researchers. This paper shows a QoS Multicast Genetic Algorithm (GA) that is applied to a multi-layer wireless system composed of a GEO DVB-RCS Satellite and a set of High Altitude Platforms (HAPs). This architecture permits of taking advantage of low HAP delay and wide Satellite bandwidth. The GA considers three QoS metrics that are cost, delay and bandwidth of multicast tree. The performance of GA, measured in terms of fitness, cost, delay and bandwidth, has been evaluated through simulations. In order to show the better performances of proposed algorithm a comparison between the proposed algorithm and a well known in literature genetic algorithm called Multi-objective Genetic Algorithm (MOGA) has been shown.
