Executive Summary

Authors present the experiences in implementing and validating the Multicast Routing protocol with Dynamic Core (MRDC) in a real wireless ad hoc network testbed. The testbed consists of portable PCs and PDAs to reduce hardware cost and facilitate mobility test. The architecture of MRDC has been designed and introduced into the user space of Linux operating system without modifying the kernel. MRDC creates and maintains a group shared tree for each multicast session on demand. Besides the routing functionality, authors designed a forwarding module in this implementation to forward all kinds of multicast datagram including MBone traffic.
