Due to large control overhead and latency, traditional multicast and unicast mechanisms are not suitable for context-aware messaging services where multiple nodes subject to a particular context receive several appropriate messages from a particular server. We propose novel multicast architecture for context-aware messaging services. By the aid of additional infrastructure our mechanism builds a multicast tree in a top-down manner from a source to multiple receivers without clients' JOIN operations while the first data message is delivered. Simulation results show that our mechanism has significantly lower overhead and latency than traditional unicast and multicast mechanisms.
