MIP attains the connectivity to nodes everywhere without user intervention. One general improvement in Mobile IPv6 (MIPv6) compared to MIPv4 is the enhanced security. However, there are areas still susceptible to various kinds of attacks. Security approaches for the MIPv6 are still in progress and there are few unsolved concerns and problems. This chapter focuses on MIPv6 security considerations, potential threats, and possible defense mechanisms. The authors discuss and analyze in detail the MIPv6 mobility management and security approaches with respect to the efficiency and complexity and bring forward some constructive recommendations. INTRODUCTION Mobile devices will undoubtedly dominate the population of the future Internet due to reduced cost, enhanced portability, increased capabilities, pervasive computing, etc. This dominance of mobile devices has made researches in mobility and security of IPv6 to be a hot area. MIPv6 allows Mobile Nodes (MN) to move within the Internet while maintaining reachabil- ity without disruption to active sessions, using a permanent Home Address (HoA). MIPv6 was designed to serve as the basic mobility manage- ment method in the IP-based wireless networks (Perkins, Johnson, & Arkko, 2011) but some shortcomings, such as prolonged handover latency Tayo Arulogun Ladoke Akintola University of Technology, Nigeria Ahmad AlSa’deh University of Potsdam, Germany Christoph Meinel University of Potsdam, Germany
