An Effective Approach for Mobile ad hoc Network via I-Watchdog Protocol
Mobile ad hoc network (MANET) is now days become very famous due to their
fixed infrastructure-less quality and dynamic nature. They contain a large
number of nodes which are connected and communicated to each other in wireless
nature. Mobile ad hoc network is a wireless technology that contains high
mobility of nodes and does not depend on the background administrator for
central authority, because they do not contain any infrastructure. Nodes of the
MANET use radio wave for communication and having limited resources and limited
computational power. The Topology of this network is changing very frequently
because they are distributed in nature and self-configurable. Due to its
wireless nature and lack of any central authority in the background, Mobile ad
hoc networks are always vulnerable to some security issues and performance
issues. The security imposes a huge impact on the performance of any network.
Some of the security issues are black hole attack, flooding, wormhole attack
etc. In this paper, we will discuss issues regarding low performance of
Watchdog protocol used in the MANET and proposed an improved Watchdog
mechanism, which is called by I-Watchdog protocol that overcomes the
limitations of Watchdog protocol and gives high performance in terms of
throughput, delay

The Digital Economy: Social Interaction Technologies – an Overview
Social interaction technologies (SIT) is a very broad field that encompasses a large list of topics: interactive and networked computing, mobile social services and the Social Web, social software and social media, marketing and advertising, various aspects and uses of blogs and podcasting, corporate value and web-based collaboration, e-government and online democracy, virtual volunteering, different aspects and uses of folksonomies, tagging and the social semantic cloud of tags, blog-based knowledge management systems, systems of online learning, with their ePortfolios, blogs and wikis in education and journalism, legal issues and social interaction technology, dataveillance and online fraud, neogeography, social software usability, social software in libraries and nonprofit organizations, and broadband visual communication technology for enhancing social interaction. The fact is that the daily activities of many businesses are being socialized, as is the case with Yammer (https://www.yammer.com/), the social enterprise social network. The leitmotivs of social software are: create, connect, contribute, and collaborate
