DISTRIBUTED CO-OPERATIVE CACHING IN SOCIAL WIRELESS NETWORK (SWNET)

Abstract

This paper introduces co-operative caching policies for reducing electronic content provisioning cost in Social Wireless Networks (SWNET). SWNET are formed by mobile devices such as laptops, modern cell phones etc. sharing common electronic contents, data and actually gathering in public places like college campus, mall etc. Electronic object caching in such SWNET are shown to be able to minimize the content provisioning cost which mainly depend on service and pricing dependencies between various stakeholders including content provider(CP),network service provider, end consumer(EC). This paper introduces practical network service and pricing model which are used for creating two object caching strategies for minimizing provisioning cost in networks which are homogeneous and heterogeneous object demand. The paper develops analytical and simulation design for analyzing the proposed caching strategies in the presence of selfish user that deviates from networks-wide cost-optimal policies.
