With the explosive growth of multimedia service, mobile computing network is necessary to satisfy with several requirements of multimedia service. Especially, session management is the core technology for supporting reliable multimedia communication. As a session management protocol, the Session Initiation Protocol (SIP) has been a very popular solution. Also SIP includes Push-to-Talk service mechanism that is well suited for one-to-many multimedia transmission. However, a centralized server based SIP architecture makes it hard to adapt directly to the mobile computing environment where network is generally self-constructed in an ad hoc fashion. To solve these challenges, this paper proposes a multimedia push-to-talk service system architecture over wireless mesh network. The proposed architecture is confirmed through the implementation and test.
