An unitary dynamic application layer multicast protocol based on genetic algorithms
Qionghai Dai · Kongzhi yu juece · 2007
Application layer multicasting process is divided into two phases,starting phase and maintaining phase.Based on system modeling and performance evaluating analysis,a protocol based on genetic algorithms is proposed to handle the both phases.During the starting phase,routing scheme based on genetic algorithms is used to optimize the overall performance of original multicast tree under several constraints.During the maintaining phase,topology recovery scheme,performance watching scheme and route updating scheme are proposed to quickly handle the frequent topology dynamics.Numerical simulations show that,compared to existing protocols,the proposed protocol improves the performance of original multicast tree and the average performance of multicast tree during the multicast process.
