Named Data Networking (NDN) has natural advantages in the consumer mobility support for its design characteristics, while the producer mobility support was left unspecified. Some producer mobility support schemes have been proposed in recent years, which better solved the huge overhead caused by the route aggregation in normal NDN, yet critical issues like long handover latency and high packet loss...
Mobility management in Named Data Networks (NDNs) is one of the main challenges of seamless operation in the future Internet. Techniques used in existing proposals for Consumer mobility are either reactive or semi-proactive, which try to reduce data access time, but yet retransmissions are required. We propose a fully proactive optimal scheme (OpCCMob) that adopts location and data patterns forecasts...
For mobile computing, it is important to have seamless mobility as the mobile node (MN) roams. Handover time needs to be optimized in order to minimize packet loss and latency. Fast Handover for Mobile IPv6 (FMIPV6) is an extension to the MIPv6 in order for a MN to regain its IP connectivity and enable the MN to send/receive data packets immediately following a handover. One of the main problems associated...
The growth of telecommunication devices has driven the development of technology of Mobile IPv6 (MIPv6), which supports the concept of seamless communication. One of MIPv6 extention is Hierarchical Mobile IPv6 (HMIPv6) were developed to reduce the delay at the time of vertical handover process by utilizing Mobility Anchor Point (MAP) whose enhancement to shorten the process of configuring the IP address...
In the existing PMIP scheme for SAE-based mobile networks such as LTE, data delivery is performed by GTP between eNB and S-GW, and also between eNBs in X2-based handover, while GRE protocol is used between S-GW and P-GW. However, the use of GTP tunnels between eNB and S-GW and between eNBs tends to induce large tunneling overhead for packets. Existing scheme also tends to incur large registration...
Named Data Networks (NDNs) offer a promising paradigm for the future Internet to cope with the growing demand for data. One of the main challenges in NDNs is how to support a seamless operation during mobility. In this paper, we investigate optimal caching for Producer mobility support and propose a scheme (named OpCacheMob) that exploits location predictors and data requests' patterns to cache the...
In this paper, a framework is proposed for interworking LTE, WiMAX and WLAN using IP Multimedia Subsystem (IMS) on top of the three technologies. The aim is to provide high quality real-time multimedia services during handoff. The proposed mobility management technique uses Mobile IP (MIP) and Session Initiation Protocol (SIP) together with IMS, which proves to maintain the continuity of an on-going...
This paper proposes an IP-based mobility management scheme supporting session continuity in user mobility and delivering packets without any encapsulation. The proposed scheme uses mapping relationship between User Identifier and Terminal Identifier. Also, it performs address translation which changes the destination address of IP packets in each communicating node for fast packet delivery.
Techniques using a nearby virtual machine (VM) based cloudlet have been proposed for mobile cloud computing (MCC) to enhance the performance of real-time resource-intensive mobile applications. After a mobile device (MD) discovers a cloudlet in the vicinity, it takes time to set up a VM inside the cloudlet before data offloading from the MD to the VM starts. The time between discovering the cloudlet...
In current generation LTE networks, user mobility leads to high levels of signaling traffic from the eNodeB (Evolved Node B) to the Evolved Packet Core (EPC) for maintaining the GPRS Tunneling Protocol (GTP) and Proxy Mobile IPv6 (PMIPv6) tunnel. Further, the presence of Packet Gateway (PGW) at the network edge introduces additional delay for every signaling procedure. In this paper, we propose an...
In the last call, we received eight submissions and accepted two articles while leaving one article to go through another round of revision and review. For future issues, we have shifted the due date by two months to February 1 and August 1 to shorten the time to publication in the September issue and March issue, respectively.
Proxy Mobile IPv6 (PMIPv6), as a network-based mobility management protocol, was released in 2008 by the IETF in RFC 5213 to support IP mobility. But in its handover procedure, network-link disconnection cannot absolutely be avoided. The IETF later proposed Fast Proxy Mobile IPv6 (FPMIPv6 for short) protocol, which was designed primarily to improve the switching process, particularly for reducing...
The newly emerging 5G mobile communication system requires an effective design of core network to cope with the mobile data traffic explosions. In this paper, we propose a new architecture for 5G mobile core network, RB-Core, to efficiently deal with such the data traffic explosion problem. The proposed RB-Core network is designed by adopting a distributed architecture and by using the Routing Bridge...
The IP Multimedia Subsystem (IMS) has been selected as a telecommunication industrial standard for the signal processing among heterogeneous access networks, and it is also responsible for mobility management. However, the mobility of the user equipment (UE) may disrupt or even intermittently disconnect an ongoing session, which heavily affects the satisfaction of the users. Therefore, how to reduce...
With the mobile network core evolving towards an unlayered and decentralized architecture, distributed mobility management appears to be more compatible and efficient with the flattened networks. In this paper, we propose a new approach to realize the distributed mobility management using the software defined networking techniques instead of the existing mobility management protocols. The mobility...
The increase of mobile traffic and the new role of the users as active elements in the network require a new approach for network architectures to adopt more flatten models. However, current mobile IP approaches were developed assuming static and centralized models: a single entity is responsible for the mobile traffic, the signaling and the context information of a large amount of Mobile Nodes. We...
Mobility management across multi technology wireless networks is an important feature for ubiquitous access. In such heterogeneous environment, service providers have to deal with service continuity especially for real time applications like voice over IP. In order to achieve this goal, the Internet Engineering Task Force (IETF) proposed fast handovers for IPv6 (FMIPv6) to reduce handover delay for...
