Comparing the performance of TCP and CBR in tree-based and mesh-based ad-hoc multicast routing protocol

This paper, evaluates the performance of two ad-hoc multicast routing protocols under varying traffic, density and mobility conditions. We observe that a large fraction of the traffic is being carried on the Internet today by TCP. Thus internet traffic has inherently different characteristics than CBR traffic, which is commonly used traffic type for evaluating MANET routing protocols performance. Previous efforts to evaluate performance of TCP and CBR in tree-based multicast routing protocol (MAODV) are done. But these tree based protocols face lot of problem like single path property, vulnerable to high mobility and large group, single point of failure which are removed in mesh-based multicast routing protocol like ODMRP, ADMR etc. It is observe that mesh based protocol are robust enough and performance of CBR is more in mesh based protocol as compare to TCP.
