Abstract:The appl ica tion of wireless adhoc netw orks 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 investiga tes the researches that use overlay (application layer) multicast over ad hoc networks, and pe rforms 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
