Abstract:The application of wireless ad hoc networks require Supporting multicast. Application layer multicasting network is one of effective solutions for the multicasting problems. Compared with the disadvantage of network layer multicast protocol, this paper comprehensively investigates the researches that use overlay (application layer) multicast over ad hoc networks, and performs extensive simulations. Based on the analysis, this paper deeply analyzes the benefits of using application layer multicast over ad hoc networks. In addition, this paper discusses the issues that need to be investigated to multicasting over wireless ad hoc networks, and presents an all-important direction to the research in the future.
Key words:wireless ad hoc networks; application layer multicast; group communication
