Information Diffusion issues

[1]. INTRODUCTION In this report there will be a discussion for Information Diffusion. There will be discussions on what information diffusion is, its key characteristics and on several other aspects of these kinds of networks. This report will focus on peer to peer models in information diffusion. There will be discussions on epidemic model, OSN and other details related to information diffusion. [2]. INFORMATION DIFFUSION Information diffusion refers to the process of spreading information. Now information spreads through networks and systems. A diffusion network is a network through which information is diffused. There are several factors that influences information diffusion. Primarily these factors are, strength of the connections among the nodes of the diffusion network and the structure, topology of the network. There are some metrics that are used to measure the quality of information diffusion. Network structure is evaluated based on the density, clustering, community structure, connected components, degree of distribution, weighted strength of the connections, strength of influence, communication frequency, spreading agent, type of information and attractiveness. A strong 'tie' or connection should have affinity, more mutual and frequent contracts. [1] Diffusion of information can range from simple to complex forms. In the simple form, it is between person to person and in complex form, individuals with thresholds are engaged. Social networks play significant role in information diffusion. Innovation is another outcome of information diffusion. But sometimes it is hindered. The 'influence' is spread through social media and its members in the form of information, opinion, innovation, ideas etc. In businesses, this is very important. They utilize this concepts in marketing and earning more revenue. Ad hoc and peer to peer networks, both share some common pitfalls. Problems in delivering messages in a network that has a rapidly changing topology. There are two methods of message delivery approaches. These two are opposite in nature. In the first approach, a node in the network communicates with others proactively by active data transmission and inquiry. On the other approach, the communication link is created on demand. In mobile peer to peer networks both approaches are applicable however, there will be significant overhead with proactive approaches when
