Abstract
With the advent of wireless and mobile technology, wireless communication is becoming more and more popular in human life. Moreover, real-time multimedia services like music and movies will indeed become important applications in wireless network.
In order to achieve higher bandwidth utilization and reduce unnecessary bandwidth waste, using multicast and IGMP to deliver high bandwidth required multimedia stream would be a trend in the future. However, they also face two important issues when used in wireless network: user mobility management and bandwidth control.
We propose a new protocol called M&M (mobile and multicast) protocol to support mobile multicast of multimedia content delivery service in wireless LANs. It is an extension of the IEEE 802.11f Inter-Access Point Protocol (IAPP) protocols and is intended to be implemented in access points. Under the new architecture, users can enjoy multimedia streaming service without interruption when roaming between APs in wireless access networks. The proposed M&M protocol supports both Intra-subnet and Inter-subnet roaming. Moreover, the proposed protocol supports the exchange of the QoS parameters of user’s subscribed service between APs to assure quality of service of the multimedia content delivery. Our protocol interworks with existing IGMP and Mobile IP as well IEEE 802.11 IAPP without modification. It is simple, flexible, and easy to implement.
