A Novel Predictive Binding Update Scheme for Fast Handover over IP-Based Wireless/Mobile Networks

These days, mobile device users are demanding a higher service due to technical development of mobile device. Because of the mobile communication traffic is magnified such as the wireless internet, SMS/MMS data services for various forms. Also, traditional wired environment has been transformed into a wireless environment. That is, wireless internet users increase, has become important in MIPv6, many services developed though 3G and WIBRO. Since 2004, MIPv6, Fast MIPv6, Hierarchical MIPv6, Proxy MIPv6 have been proposed due to improved performance by developing more protocols and related technologies, many studies currently underway. Has been the hottest issue in MIPv6 the mobile device other issues that occur when moving between Base Stations handover latency and packet loss and packet accordingly phenomenon is reversed. In this paper, we used beacon Messages, Look-Up and Reverse Binding. So, we are proposed to solve these problems by using the proposed method.

MSMAP: A Study on Robust Multiple Selection Scheme of Mobility Anchor Point in Hierarchical Mobile IPv6 Networks

In Hierarchical Mobile IPv6 networks, how a mobile node selects an appropriate mobility anchor point (MAP) has a vital effect on the overall network performance. In this paper, we evaluate the performances of MAP selection schemes: the furthest MAP selection scheme, the nearest MAP selection scheme, the mobility-based MAP selection scheme, and the adaptive MAP selection scheme. The dynamic schemes can achieve load balancing among MAPs, where the adaptive MAP selection is better than the mobility-based MAP selection scheme. We also discussed our proposed scheme which is called the Multiple Selection of MAP in HMIPv6 (MSMAP-HMIPv6). We will show the comparison of performance analysis of HMIPv6 and our propose scheme, based on the assumptions of the new scheme, we can minimize the signaling of the mobile node and based on the pre-binding update research can minimize the handover latency.

PER Measurement of Vehicular Communication Systems with Adjacent Channel Interferences

Error performance is a critical factor to support reliable communication links. In this paper, we measure packet error rate (PER) of vehicular communication systems when the adjacent channel interferences exist. The measurement is carried out in the rural area. We use IEEE 802.11p standard for vehicular communications. First, we briefly review the physical layer properties of IEEE 802.11p standard. Then, we represent the measurement results of received signal strength indicator (RSSI). Finally, the PER measurement results are introduce by considering the adjacent channel interferences. Based on the measurement results, we discuss the reliability of vehicular communication systems.

A Software Framework for Optimizing Smart Resources in the Industrial Field

Recently, there are many industries that use smart resources such as smart phones. If we use smart resources, we can get information from anywhere and at anytime. In this environment, we can use various useful information when we scheduling the resources. However, optimizing these resources automatically is still hard since the field industry has various types of environmental factors generally. In this paper, we present the software framework that can optimize the use of the smart resources in the field industry. The framework takes various environmental factors in the field industry as input data. Then, it generates solution by using various optimization algorithms. The solution can be diverse since various objective functions and constraints can be selected. Finally, we implemented the framework in the real industrial field. As a result of this, the usage ratio of the resources was improved by 27%.

A Study of Flow Mobility Management Architecture for Multimedia Contents over Software Defined Networks

The Internet usage is continuously becoming more and more popular in an unprecedented rate that results into a more complex distribution of multimedia contents over the heterogeneous wireless networks. The standardization and optimization of several mobility management protocols were limited and suffering from numerous drawbacks such as routability issues, higher handover latency, signaling overheads and other mobility related issues. To address these issues, this paper deals with the analysis of a flow mobility management architecture for a balanced distribution of multimedia contents over software defined networks (SDN). The SDN has been an effective alternative for the mobility management as well as on the delivery of multimedia contents over the heterogeneous wireless networks.

A Design Method Using SOA Paradigm for Mobile Cloud Computing Services over Multimedia Convergence Networks

The Smart Phone market is gradually being extended, and Mobile communication devices in the form of a miniaturized computers has evolved. However, there are limitations due to the nature of the smart phone devices, operating systems and applications is an obstacle in driving. A solution to solve these problems for mobilecloudcomputing technology is attracting attention. However, low compatibility between services without clear standards and specifications is Free. In this paper, in order to solve these problems, utilizing SOA, mobile computing, integrated interface to configure a methodology for cloud services is proposed.

A Design of Safety Multimedia Packet Transmission DB System Management Scheme

These days, the concern of security increased suddenly due to the damage about leakage of personal information by network security variability to cybercrime attacks. The wireless users are increasing, as it increases the wireless services are also more vulnerable to hacker’s attack compared to wired services. In order to resolve these problems, it is very important to supports a good quality services to the wireless users. The wireless network should reduce the handover delay time. In this paper, we proposed a scheme that provides multimedia strong security packet transmission database system with fast handover by using key in WCN.

In the IETF, when the handover occurs on wireless network environment, it proves Mobile Node’s uniqueness and security, and encourages the RR technique and security system comparable for safe Route Optimization. To complement weakness about technique for obtaining an existing security, security agreement that uses an independent AAA Protocol in aspect of infrastructure is now under discussion. With the utilization of the AAA infrastructure in this thesis, it maintains established security level and suggests a technique that improves Quality of Service as fast handover by constructing security system based on ISPC structure.

Recently, the Wireless internet user increased drastically due to the increase of concerns about the performance improvement of the mobile device and Smart phone. Wireless device users required the service which has a higher and the Mobile Communication traffic of the voice was expanded to a various multimedia services which includes various forms of voice data service- centered including wireless internet, SMS, MMS, and etc. The significant importance of Mobile IPv6 stood out as the user of the wireless internet increased and various of mobile service rapidly developed such as 3G and WIBRO. In Mobile IPv6, when the mobile device moves it possible creates a controversial issue between the base station, the packet loss according to the handover generates a delay time and it reverse the handover of packets and it’s process. In this paper, we present a novel method of solving the problems packet handover. We based our proposed packet handover scheme on the existing handover process.
