An Interest-Aware Caching Scheme for Mobile Devices

Mobile services are gaining importance in handling data on mobile devices. With heaps of information flowing in the network, a service for caching preferential posts will be helpful. Understanding the profile of an individual in a social network will help determine the relationship value with respect to other individuals in the network. Similarly a post in a social network can have contexts associated with it. If these contexts are a priority to the user, they can be one of the deciding factors for pre-fetching. In summary, these values called the profile similarity value and context priority values can be used to determine strengths between individuals and their preference. Getting a uniform bandwidth is always a challenge due to the mobility of the device. In this context pre-fetching of posts most related to the user can be beneficial in increasing the social network experience on mobile devices. The value addition is that the cached data apart from being personalised it can also be consumed later and helps when the individual moves to a place with no bandwidth or even a narrow bandwidth. This paper considers the personal similarity value as social network strength coupled with context priority of the post determined by the user, to evaluate what posts could be cached.
