Recently as the mobile computing is burgeoning, multimedia services have become very popular. Multimedia services require large data volume and have to send the same data to several users. In order to provide efficient multimedia services that have those characteristic to mobile users, efficient multicast technique to support host mobility is required. Previous research that support multicast services in mobile computing based on Mobile IP have the non-optimization problem of data delivery path, overhead by frequent reconstruction of the multicast tree, and service disruption problem. In this paper, we propose the mobility pattern based multicast technique using variable service range according to the mobility of mobile hosts and resource reservation to solve this problems. The experimental results show that our proposed mechanism has improved performance than previous research. |
