Design and implementation of end to end 3G network emulation system

The 3G wireless mobile network will witness bright future in the coming days with high bandwidth and end mobility.However,it is not convenient to conduct research without real 3G network.Therefore,it is necessary to construct a test environment which can emulate the end to end characteristics of 3G network.The 3G wireless mobile network emulation system is designed and implemented by enhancing Nistnet,a famous open source project.
