Abstract
Mobile networks can be categorized to edge and core networks. The edge network main function is to interface the end-user to the core network; taking into consideration different traffic types such as voice, video, and data. Nowadays, the end-user equipment are equipped with TCP/IP stack; so it can be looked as minicomputers connected with IPv4 or IPv6 protocols. On the other hand; the core network; independent of the edge networks, can be any of the common core networks such as IPv4, IPv6, MPLS, and ATM. The end-to-end operability and performance depend on both of the edge and core networks technologies. It is important to study the impact of various technologies on mobile core networks. Performance analysis is done on the technologies to compare between them. Comparison, using network simulation tools, is done over several performance aspects; such as mobility, delay, addressing, utilization, interoperability…etc.
One of the major problems faced by different wireless networks nowadays is the mobility. Inter-Radio Access Technologies handovers, roaming, and application continuity problems motivate the MIPv6 rather than MIPv4. This work covers the main benefits and drawbacks for the different mobile IPs via literary and simulation discussions. Using IPv4 tunnels to carry MIPv6 as an alternative to the native MIPv6 is discussed also, in case of not all-IPv6 network is used.
End-to-end delay is a major performance aspect to be monitored in any core network. This depends on the end-to-end IP technology used whether it is IPv4 or IPv6; also it is changed in case of using mobile IP. This work focuses also on real-time traffic performance under different core network technologies. from the end user operation point of view; core network technology has to be transparent with respect to the end user mobile protocol. Using MIPv4 and MIPv6 is studied in this work on IP backbone and ATM backbone; also using IPv4 backbone to support MIPv6 via tunneling is covered here.
