Network based micro-mobility architecture for 6LoWPAN

다국어 초록 (Multilingual Abstract)

thesis provides an in depth analysis of the existing mobility support protocols in terms of different aspects of mobility management such as location management, handover management, routing, route optimization and security. Also it discusses the goals and mobility requirements of 6LoWPAN. A network based micro-mobility management architecture is proposed for 6LoWPAN. The micro-mobility management architecture embodies three schemes. The first scheme is LoWMob, which is a network based mobility scheme aims to provide mobility support
to mobile 6LoWPAN nodes at the adaptation layer of the 6LoWPAN. In order to achieve that, LoWMob proposes to utilize 6LoWPAN’s adaptation layer message format and 16 bit addressing scheme to carry mobility related signaling. A distributed version of LoWMob(DLoWMob) is proposed in order to distribute the traffic concentration at the gateway. Route Optimization of data packets of two mobile nodes located in the same PAN is also considered. A security scheme is also proposed in order to provide mutual authentication of the MN and a PAN and to secure MN’s data packets. The third scheme is LoWPMIPv6 which is a lightweight implementation of PMIPv6 (LoWPMIPv6) for 6LoWPAN. It provides mobility support at the network layer and proposes compression of mobility related messages in order to reduce the overhead on the PAN nodes. The three schemes (LoWMob, DLoWMob and LoWPMIPv6) is
then compared in order determine their suitability for 6LoWPAN. The performance of our proposed schemes is evaluated in terms of mobility signaling costs, end-to-end delay, and packet success ratio both in Qulanet and analytically.
