Due to the new characteristics of ultra-dense networks (UDN), such as high dense deployment of wireless access points (APs), complicated handover signaling processes and irregular coverage, how to achieve mobility support and reduce user's interrupt ratio remain a difficult problem. To address these issues, based on the presented user-centric APs clustering (UCC) network architecture in UDN, a UCC...
User demand for content has become more evident and content service (text messages, video on demand) has become the main network service. Thus, the Content-Centric Networking (CCN) has become the research focus of next-generation Internet architecture. However, the requirements of supporting content provider mobility are not considered. To solve this problem, we propose proactive caching of vital...
Ultra-dense networking (UDN) is considered as a promising technology for 5G. In this article, we define user-centric UDN (UUDN) by introducing the philosophy of the network serving user and the "de-cellular" method. Based on the analysis of challenges and requirements of UUDN, a new architecture is presented that breaks through the traditional cellular architecture of the network controlling...
Being a key computing element in cloud data center, virtual machines should be able to migrate from one location to another to meet the requirements of the cloud users and the defined policies of the cloud computing system. The mobility is an important issue when a virtual machine migrates across IP subnets. This paper focuses on the mobility management in cloud computing systems, and proposes a mobility-oriented...
Content centric networks (CCN) is a new content-oriented network paradigm. It changes the communication mode from where to what. CCN can realize efficient content transmission and support consumer mobility inherently because of its receiver-driven characteristic. But it cannot handle provider mobility effectively since the movement will lead to the entire routing information updating. In this paper,...
Long registration delay and signaling cost restrict the practical deployment of MIP. Proxy Mobile IPv6 has been proposed to overcome limitation of Mobile IP, which can avoid tunneling overhead and support of hosts in the mobility management. In this paper, we propose an extension protocol based on Proxy Mobile IPv6 to reduce the overhead of Local Mobile Anchor and decrease handoff delay. When the...
With the rapid growth of wireless communication technologies and mobile applications, more and more mobile terminals need to access Internet seamlessly. Due to the IP address acts as both identifier and locator for a mobile terminal, it cannot guarantee the service continuity when a mobile terminal keeps moving. An efficient mobility management schemes for a mobile terminal is important. The Host...
At present, the number of Internet subscribers accessing Internet through mobility terminal equipment and other new types is gradually increasing, which shows it's important to develop mobility management protocols in order to provide mobility support for the subscribers. Several protocols were proposed to support IP mobility in the IETF, such as MIPv6, HMIPv6, FMIPv6 and F-HMIPv6. Some performance...
To support mobile nodes moving across different networks as a whole, the IETF NEMOv6 (RFC 3963) has been proposed. Compared with Mobile IPv6 protocol, the NEMOv6 provides a method to enable a network moving entirely. Mobile Router (MR) is introduced to the NEMOv6, which performs mobility management function for the entire mobile network. All nodes belonged to the mobile network, fixed or mobile, are...
