Title:Smartphone Applications–A Comparative Study Between Older And Younger Users
Author Name:Tom Page
Synopsis:

This research considers whether smartphones satisfy the needs of all generations. The research methods used a user questionnaire, (n=60) divided equally between young and old consumers and an interview conducted with six smartphone users. The main findings were that, both groups require efficient functionality with regards to basic smartphone activities such as making phone calls and sending text messages, but that the difference lies in how much the two sets of consumers viewed social media access as an important feature. While older users showed little concern for socially orientated applications, the young consumer group showed a dependence upon it as an aid to their daily lifestyle. The study concluded that whilst basic functionality is a standard requirement for any user, the exponential growth of technology and increasing demand for social communication has caused a divide between the young and old consumers. The market is now dominated by the younger generation and so the older users' needs and requirements are shown to be overshadowed in current smartphone design.

Synopsis:

The fourth generation wireless communication systems have been deployed or are soon to be deployed in many countries. Wireless system designers have been facing the continually increasing demand for high data rates and mobility required by new wireless applications and therefore have started research on fifth generation wireless systems that are expected to be deployed beyond 2020. In next-generation wireless data networks, Massive Multiple Input Multiple Output (MIMO) is an exciting area of 5G wireless research. It promises significant gains that offer the ability to accommodate more users at higher data rates with better reliability while consuming less power. Massive MIMO has been identified as one of the promising disruptive air interface technologies to address the massive capacity requirement demanded by 5G wireless communications. Massive MIMO, also called Large-Scale Antenna Systems, is a promising candidate technology for meeting this demand. In this paper, the authors have discussed various promising technologies for 5G wireless communication systems, such as massive MIMO, energy-efficient communication techniques, and the key challenges and potential technologies for smart mobiles.

Title:Design of Secure Location And Message Sharing System For Android Platform
Author Name:Juby Mathew 
Synopsis:

Recently, there is a substantial surge in usage of mobile internet. Thanks to wide range of new Smart phones which are significantly capable to display full websites on small screens than ever before. Android stands out more than others because of its Multitasking, Ease of Notification, and Easy access to thousands of applications via the Google Android App Market, diverse Phone options. Present android-based location and message sharing system asks to input the personal information which fails to protect the privacy of information, has no centralized database which is causing the problem of data management and portability, and one main drawback is unable to have a secured two way communication between web server and android based application.

The Navel Security based approach of integrating group communication and navigation in android gadgets provides effective group communication and navigation. The system intends to achieve two major functions. First function is the effective group communication which provides all registered users to create friend groups, implement real-time communication. Second function is navigation which provides Map service and navigation function on the mobile client for users. It can support the surrounding query, location, path planning etc. Meanwhile, the two parts of the system can be integrated to locate the friend's position and implant path planning between friends. Security is the major concern for such group communication, in this proposed approach an encryption scheme is implemented to ensure secure communication. When a new user comes for registration, a set of images will be provided to him for selection. The user has to enter his username and an image is also required to select. When the user selects the image, that will be compared with the one that he has already selected. If the current image and the selected one match, then he would be allowed to enter the password. Hence, proper security for the system can be ensured.

Title:Energy Based Geographic Routing in Mobile Ad Hoc Networks
Author Name:Vemana Chary, Padmanabham and Bhima Prabhakara Rao
Synopsis:

In MANET (Mobile Adhoc Network), power is one of the major issue. MANET devices depend on limited battery power. However, routing in mobile networks is a challenging task and requires specialized routing protocols that are designed to cater to mobile environment factors, such as node connectivity, life time of node mobility, data transmission and Packet Delivery Ratio. This paper proposed a new scheme called Enhance Adaptive Position Update (E-APU) routing protocol which improves the existing on-demand routing protocols by introducing a power efficient scheme in the whole MANET. The main goal of this paper is not only to extend the lifetime of each node, but provides the lifetime of each node connection with low power consumption.

The paper presents a qualitative comparative study of geographic position based routing protocols with forwarding strategies for energy consumption and end to end delay. With the growing popularity of positioning devices, geographic routing protocols are one of the choices for use in Mobile Ad hoc Network. Periodic broadcasting of packets that contain the geographic location coordinates of the nodes is a popular method used by most Geographic routing (GEO) protocols to maintain neighbor positions. Ultimate aim is to reduce the energy consumption and receive more packets at minimum end to end delay with adaptive position updates. In addition, this proposed Enhance Adaptive Position Update (E-APU) scheme dynamically gives better solution for node movements.

Title:A Scalable Server Architecture for Mobile Presence Services in Social Network Applications
Author Name:A. Radha Krishna and K. Chandra Sekharaiah
Synopsis:
The use of social network is becoming gradually more popular on mobile devices. The important component of a social network application is a mobile presence service as it continuously uploads the existence information of each user's resembling online or offline, GPS site keep posting of friends information continually. In large-scale mobile presence services, if continuously keeping up to date information, then the huge number of messages shared out by the presence server may show the way to a scalability problem. So, the authors planned for an well-organized and scalable server design called Presence Cloud, to address the problems. Presence Cloud allows mobile presence services to support for the social network applications. Presence Cloud finds the existence of his/her companion and inform them of his/her appearance when a mobile user joins a network. For efficient presence searching, Presence Cloud categorizes presence servers categorized interested in a quorum-based server to server design in support of well-organized existence penetrating presence Cloud. To achieve small constant search latency like Directed search algorithms and a one-hop caching strategy, is also controlled by it. The authors scrutinized the presentation of Presence Cloud in periods of the search rate and search approval levels. Overall messages produced by the presence server when a user appears is called as the search rate. Search approval stage is characterized as the instance it obtains to find the new or in words user's companion catalog. The consequences of replications exhibit that Presence Cloud accomplishes presentation in the search rate without compromising search approval.
