To provide Internet access for MANET, the interworking mechanismbetween MANET and IP based fixed network is needed, which has become a vivid research area.However, so far, little work has been done to connect the multicast protocols on both sides so thatusers can access multicast services on either side. In this paper, a so-called Modified MLD (M. MLD)is proposed as a solution to IPv6 multicast interworking between MANET and fixed networks.展开更多

This paper sets out to answer the question of how to construct multicast tree on top of IPv4-IPv6 hybrid network. Our solution is a New Greedy Algorithm (NGA) which eliminates the problem of joining failure in the hybrid network and keeps the efficiency of greedy algorithm in tree construction. Simulation results show that our algorithm has excellent performance, which is very close to the optimal in many cases.展开更多
