Dynamic content management for mobile subscribers: a survey

Abstract

Managing dynamic content in mobility challenged by the repeated handoffs and dynamic changes in wireless topology. Commercially deployed content management approach, Content Distribution Network (CDN) implemented as application layer overlay and transported by Mobile IPv6 (MIPv6), surveyed with the Future Internet Architecture namely Content Centric Network (CCN) that maintain in-network caching and content distribution directly in the network layer. While the former successfully deployed, it tightly binds the end-to-end approach and might does not scale with the Information centric paradigm shift. The latter approach is promising however still at its infancy and not yet scale with the global Internet infrastructure. We cover three mobility scenario: (i) consumer mobility with static content provider, (ii) static consumer with mobile content producer, and (iii) mobility of both content consumer and provider, and review approaches under both content managements.
