Currently, the technology trend indicates that billions of handheld gadgets as well as other types of mobile devices will be coming online in the next few years. Mobility is important in mobile communication. While the existing Internet mobility standards, namely Mobile IP, is waiting for a wide adoption, cell phone networks are providing the ubiquitous mobility services on a global scale as of today. This paper will explain how to implementing IP Mobile in wireless access point. It can be done by two methods that are Distributed DHCP (MAC reserved) and Centralized DHCP (Bypassed DHCP) with maintaining IP. However, in the movement of IP mobile from one access point to another access point there is delay time that we called delay IP and delay activity

ABSTRACT The following paper describes the challenges of providing consistent authentication procedures across WLAN hotspots owned by different operators, where the set of credentials that the user should present to the network can be quite large depending on user subscription and inter-operator roaming agreements. This paper provides a description of the set of features that are needed to support secure, authenticated access to the network, and highlights how current authentication solutions provide at least some of these features. Finally the paper introduces two new techniques for enhancing the operation of these authentication solutions to provide a consistent "look and feel" and level of security across different hotspots.

The Control And Provisioning of Wireless Access Points (CAPWAP) protocol is under definition within the IETF to enable an Access Controller (AC) to manage a collection of Wireless Termination Points (WTPs). CAPWAP aims at simplifying the deployment and control of large scale, possibly heterogeneous, wireless networks. We present the first open source implementation of the CAPWAP protocol along with early experimental results aiming at the assessment of its reliability and performances. The paper ends describing applications of the CAPWAP protocol to management and QoS scenarios and discussing benefits and technical issues concerning its use.

In this paper we propose and describe a unified solution for interoperability between mobile cellular network and WLAN. The integration between two networks, cellular and WLAN, is performed on the Authentication, Authorization and Accounting i.e. AAA side. For that purpose we developed WLAN Access Controller and WLAN AAA Gateway, which provide gateway-type access control as well as charging and billing functionalities for the WLAN service, respectively. In the development process of these elements we have considered current development stadium of all needed network entities and protocols. The developed solution provides costeffective and easy-to-deploy PLMN-WLAN internetworking scenario.

The growing ubiquity of Wi-Fi networks combined with the integration of low-cost Wi-Fi chipsets in all devices makes Wi-Fi as the wireless technology the most used for accessing to internet [1]. This means that the development of a Wi-Fi strategy has become an imperative for almost all operators worldwide. In this context, APs (Access Points) have to become as secure as cellular networks. Furthermore, authentication process between a mobile device and an access point has to be automated, without user constraining configuration. For reaching this purpose, client must have different credentials depending on authentication method. Our goal is to create an architecture that is both ergonomic and flexible in order to meet the need for connection and client mobility. We use NFC technology as a radio channel for starting communication with the network. The communication initiation will instantiate a virtual Wi-Fi AP and distribute all policies and access certificates for an authentication based on EAP-TLS (it could be extended to any EAP method for 802.1X standard). The end result of our new topology is to allow access to services through a virtual Wi-Fi AP with an enterprise-grade in a public hotspot.

Although peer sexual health education is a common form of sexual health promotion for youth, systematic reviews of these programs are relatively rare. In this study we interviewed youth peer educators to inquire about their experience of program evaluation and their perception of what is needed to develop effective evaluation practices. Data were collected from eighteen participants in semi-structured qualitative interviews of youth (aged 16-28 years) sexual health peer educators in Ontario, Canada. Community-based research principles were employed throughout the project with youth involved in all stages of the research. Analysis of the data revealed four key themes relating to youth sexual health peer education evaluation: i) varied program goals; ii) benefits to peer educators; iii) diverse evaluation methods; and iv) challenges in conducting evaluation. We discuss the relevance of our findings for evaluation practices of peer sexual health education programs.

Purpose of the article: In this paper authors focus on analyzing how culturally based differences in terms of Hofstede's cultural dimensions affect the process of building PR campaign strategy. Methodology: Using two case studies of the same global company from two culturally diverse environments authors compare how distinctive features of each culture is being reflected into the concept, form and language used within the PR campaigns. The first analyses campaign "Solve for Tomorrow" took place in the US environment which represents highly individualistic and masculine culture with strong emphasis on task and success, comparing to relationships. The other campaign called "The Touchable Ink" took place in Thailand which, on the contrary, is considered very collectivistic and feminine culture with strong prevalence of relationships over tasks. Scientific objective: The article highlights the importance of understanding cultural values of the target market and reflecting them by building PR strategy, and demonstrates this approach on the example of two case studies. Findings: By comparison of two case studies from the United States and Thailand we can clearly see how the low versus high scoring in the areas of Individualism and Masculinity in terms of Hofstede's cultural dimensions affects the concept of the campaign. In the United States as a highly individualist and masculine country, the campaign "Solve for Tomorrow" takes form of a contest and strongly emphasizes attributes like competing and achieving goals. In Thailand, as the exact opposite of the United States in terms of Individualism and Masculinity scoring, PR campaign "The Touchable Ink" was built as an awareness campaign with strong emphasis on helping the visually impaired, focused on improving the quality of their everyday life. Conclusions: The presented paper highlights the importance of knowing and understanding the cultural environment by preparing PR campaign strategy and supports the contention that even for a global company it is still worth considering local thinking by using marketing communication tools.
