A Review of Network Based Mobility Management Schemes, WSN Mobility in 6LoWPAN Domain and Open Challenges <s> Conclusion <s> This article presents an overview of a set of IP-based mobility protocols mobile IP, HAWAII, cellular IP, hierarchical MIP, TeIeMIP, dynamic mobility agent, and terminal independent MIP - that will play an important role in the forthcoming convergence of IP and legacy wireless networks. A comparative analysis with respect to system parameters such as location update, handoff latency and signaling overhead exposes their ability in managing micro/macro/global-level mobility. We use this observation to relate their features against a number of key design issues identified for seamless IP-based mobility as envisioned for future 4G networks. <s> BIB001 </s> A Review of Network Based Mobility Management Schemes, WSN Mobility in 6LoWPAN Domain and Open Challenges <s> Conclusion <s> This document introduces extensions to Mobile IPv6 and IPv6 Neighbour ::: Discovery to allow for local mobility handling.

In this article, we presented a brief description of host based mobility management protocols along with a complete study of network based mobility and 6LoWPAN WSN mobility management schemes. A comparison of available mobility solutions based on network mobility for WSN in 6LoWPAN is also presented. Further the article presents some of the challenging areas in mobility management where improvements are still needed. One such area highlighted in this paper is healthcare (HWSN), where patient's mobility is continuously monitored inside the hospital premises. Already existing mobility approaches  BIB001 BIB002 are tunnel based where sensor nodes have to send lot of signaling messages and not suitable for 6LoWPAN mobility. Therefore, the suggested FHPMIPv6 is best suitable for reducing packet loss and HO latency. In future, an attempt would be made for practical implementation of FHPMIPv6 for the critical areas in WSN. Also a study of security issues in 6LoWPAN WSN will be performed with emphasis on Biometric security in 6LoWPAN WSN mobility as very less work has been done on implementing Biometric security in 6LoWPAN.
