Ever increasing demands of users and rapid development of telecommunication technologies have led to the evolution of 4G heterogeneous wireless network. Further, 4G with heterogeneous network environment will provide features such as seamless internet connectivity between different wireless networks, " Always Best Connected " service and " Anywhere Anytime(More)
—The " explosive growth in bursty traffic " changes the network dynamics and requires a good evaluation of various classes of service when designing an access network. From a topological standpoint, the multiservice networks in this paper are heterogeneous systems which integrate both a core and some wireless access networks into an infrastructure similar(More)
