Technical Paper Review - Reconfigurable Architecture and Mobility Management for Next-Generation Wireless IP Networks.pdf

I have been assigned to present this speech on the Technology Entrepreneurship course next week, but I misread the presentation time and thought I should have gave the presentation today.
As a consequence, I didn't sleep and spend about 4 hours reading the paper quickly and creating this slides. Orz

1. Technical Paper Review: Reconfigurable Architecture and Mobility Management for Next-Generation Wireless IP Networks http://nthur.lib.nthu.edu.tw/handle/987654321/42070 Shun-Yi Jheng 2015/04/07
2. Abstract & Introduction (1) • Radio Systems ◦ Small areas, Higher data rates, Lower power ▪ WiFi v.s. 3G • Wireless System ◦ Radio Access Networks (RANs) & Core Network • Difficult to roam from one system to another ◦ Incompatible wireless systems. ◦ Different RANs optimized for different environments and requirements. ◦ Different standards, different core networks and protocols. ▪ 3GPP, 3GPP2, WiMAX
3. Abstract & Introduction (2) • How to roam among heterogeneous networks easily? ◦ One-to-one consideration of each specific system? ◦ A terminal with a multi-mode radio or multiple radio interfaces, connect to a common core network? ▪ only allow a terminal roam into few predefined radio systems. ▪ Software Defined Radio (SDR) has been proposed.
4. Abstract & Introduction (3) • RAMP - Reconfigurable Architecture and Mobility Platform ◦ Provide a long-term solution to fit different requirements of mobility management dynamically. ◦ Integrate heterogeneous wireless networks. ◦ Programmability v.s. Security concern ▪ Users can only choose predefined modules to execute rather than programing the network freely. ◦ A complete reconfigurable system which includes network and terminal. ◦ Can be realized without changing the standard IP protocols. ◦ Not incur high signaling cost.
5. Mobility Management Protocols • Mobile IP (MIP) ◦ Support terminal mobility in IP networks without changing IP routing. ◦ Frequent location update, long handoff delay, and long end-to-end latency. • Macro-mobility management - Based on MIP • Micro-mobility management ◦ Limits frequent handoffs into micro-domains to reduce handoff latency. ◦ Tunnel-based protocols ▪ employ a hierarchical mobility architecture or require a mobility gateway to tunnel packets to and from mobile stations. ◦ Host-specific-routing-based protocols ▪ adopt new routing schemes to support mobility within the micro-domain.
6. Reconfigurable Architecture and Mobility Platform • Network Node (NN) & Mobile Node (MN) Architecture • Realization in IP Networks • Processing Flow • Characteristics of RAMP
7. Analysis & Results • Analysis of Signaling Cost in RAMP ◦ The performance of other metrics heavily depends on the protocols incorporated into RAMP.
8. Testbed & Experiments • Reconfigurability • Coexistence • Summary ◦ RAMP architecture can be realized in real life. ◦ Can use layer-2 mechanisms to reduce handoff latency. ◦ RAMP can coexist with standard IP networks.
9. Conclusion • Not be necessary/possible to define a single universal Core Network. ◦ Different core networks and protocols could coexist. ◦ RAMP is a first step toward this paradigm. • RAMP architecture ◦ Network Node (NN) ◦ Mobile Node (MN) • Analytical models to compare the signaling cost ◦ RAMP does not incur high signaling cost. ◦ RAMP can achieve reconfigurability for various mobility management protocols.
10. Future Work • Security Problems ◦ Security protocols ▪ Different security protocols could be implemented in RAMP. ◦ Architecture security ▪ Analyzing the proposed architecture with security consideration. • The reconfigurability of macro-mobility management • How to incorporate the newly evolving networks defined by 3GPP and 3GPP2.
