碩士 === 國立臺中教育大學 === 資訊工程學系 === 101 === There are numerous mobile objects in the future IoT environment, such as human being, animals, vehicles, and public transportations. It is critical to design an efficient mobility management scheme to provide the mobile nodes with seamless network usage. In the recent years, PMIPv6 (Proxy Mobile IPv6) has become a key role to solve the problem of mobility management in IoT. There have been many researches apply PMIPv6 in ITS (Intelligent Transportation System), healthcare, and smart home applications. The most significant feature of PMIPv6 is network-based mobility management that make mobile nodes do not need to involve and aware of the mobility management process. Consequently, the number of control messages and power consumption of the mobile nodes are remarkably reduced. With this feature, PMIPv6 is more suitable for the resource constrain environment. However, PMIPv6 is designed based-on local mobility management that limits the mobile nodes moving around different PMIPv6 domains. This problem is detrimental to supply ubiquitous services in IoT. In spite of PMIP-MIP Interaction which proposed by IETF attempts to solve the local mobility problem of PMIPv6, it causes many unnecessary control messages. Moreover, in ITS, a group of mobile nodes may move together with the human or transportations. Therefore, this thesis proposed a network-based mobility management which supports global mobility and group mobility. As shown in the performance analysis, the mobility management scheme proposed in this thesis can shorten handover delay, lessen control messages, and reduce energy consumption.
