Mobility Management for All Mobile IP
Department of Computer Engineering, Faculty of Engineering,
Prince of Songkla University (PSU), Thailand
Abstract: In this research work, we would like to present the distributed mobility management for mobile network. The solution provides two mobility approaches. The first one is a distributed mobility solution based on NEMO for heterogeneous mobile IP networks. This solution deploys multiple Home Agents (HAs), and the mobility anchors are closer to the edge of the network in order to provide optimal routing and lower delays. The performance evaluations are provided in terms of handover latency, signaling and packet delivery costs, and end to end delay. Another solution is based on Software-Defined Networking (SDN) that provides network operators to easily and quickly introduce new services and flexibly adapt to their requirements. This solution offers some of advantages including no need to deploy any mobility-related component at the access router, independence of the underlying technologies, and per-flow mobility support.

Development of flexible pressure sensors for the ambient information society
Department of Electronics and Informatics, Faculty of Science and Engineering, Kokushikan University, Japan
Abstract: In this research work, the development of sensors which are fabricated on the flexible substrates is presented. In particular, we have been focusing on the pressure sensors. Flexible pressure sensors have been intensively developed to be utilized in the health care field, in areas such as artificial skin, human pulse measurement systems, sensors for the detection of bedsores, and sensor sheets for floors. Application of functional organic materials, such as piezoresistive, capacitive or piezoelectric material, to active layers of sensing elements is promising for the development of flexible sensors, where the active layer is sandwiched between two electrodes. In order to enhance the signals from the sensing elements, integration of the elements with organic transistors has been one of the reserch interests. Recently, we have developed the dual-gate organic pressure sensor in which a piezoelectric sensing capacitor was stacked on a low-voltage Organic field-effect transistor. This device was fabricated by means of solution process on a flexible plastic substrate. The detail and potential application of the device will be introduced.
Evolving Multipath TCP in Next Generation of Mobile Wireless Networks
Graduate School of Engineering, Chiba University, Japan
Abstract: Multipath TCP (MPTCP), which is an IETF standardized transport protocol, has been available on a vast number of devices. MPTCP allows an application (e.g., on a mobile phone) harnesses resources of multiple wireless links simultaneously, hence enhancing throughput and resilience. In this talk, we will introduce our MPTCP research in the context of the next generation of mobile wireless networks (i.e., 5G). First, we describe how to efficiently adopt MPTCP in the evolved 3GPP network architecture, which leverages the so-called dual connectivity technology. Second, we propose a novel MPTCP-based system that lets millimeter-wave wireless link (i.e., IEEE 802.11ad) with multi-Gbps capability evolves in Wi-Fi networks. Finally, we present a few proposals, including concurrent initialization, path-awareness scheduling, which improve the standard MPTCP performance in heterogeneous wireless networks.
