Development and usage of online social networking web sites are growing rapidly. Millions members of these web sites publicly articulate mutual "friendship" relations and share user-created contents, such as photos, videos, files, and blogs. The advances in web designing technology and fast growing usage of online resources prompted web designers to improve features and architectures of social ...

The traditional view of Internet of Things (IoT) attempts to connect all the physical objects to build a global, infrastructure-based IoT. In this paper, however, we will present opportunistic IoT, which is formed based on the ad hoc, opportunistic networking of devices (e.g., mobile phones, smart vehicles) using short-range radio techniques (e.g., Bluetooth, Wi-Fi). The opportunistic IoT demon...

Mobility modeling is an essential component of wireless and mobile networking research. It assists planning, developing and evaluating protocols and mobile systems. A simulated mobile world provides flexibility for constructing scenarios that closely resemble the real world. Our proposed mobility model emphasizes humans’ social roles when making movement decisions. Our model, the Agenda Driven ...

The demand for data/audio streaming/video streaming multicast services in large scale networks has been increasing. Moreover, the improved transmission speed and mobile-device capability in wireless access networks enable people to use such services via their personal mobile devices. Peer-to-peer (P2P) architecture ensures scalability and robustness more easily and more economically than server...

The spatially and temporally diverse nature of ad hoc networks strongly suggests the development of a sophisticated multi protocol network-layer that should enable the ad hoc network's nodes to dynamically change the routing protocol as networking scenarios demand. In short, the routing protocol is to be considered a system variable. However, the autonomous reconfiguration of such a dependent v...

Mobile phones and social media enable people to share information with others whenever they want, wherever they want. More recent developments allow people to augment their sharing experience by geo-tagging their information through GPS enabled phones. These ’locative media’ can be used to facilitate navigation, way finding or to obtain information about a physical place or object. Other servic...

INTRODUCTION Online social networking services such as Facebook (www.facebook.com) have continued to increase in popularity , likely due to the accessibility of mobile internet on smart phones and tablets. Between 2010 and 2011 alone, the number of mobile Internet subscribers increased by 45% (7). Among consumers aged 16 and over in the UK and US, it is estimated that 95% own mobile devices (8)...
