What is IEEE 802.21

Chapter 34
Handbook of Research on Mobility and Computing: Evolving Technologies and Ubiquitous Impacts
is a standard that aims at optimizing handovers between heterogeneous IEEE 802 networks access, as well as facilitating handovers between IEEE 802 networks and cellular networks. In order to do so, this standard defines commands (to trigger decision-making) and events (of link conditions) by using information of MN and of network.

Abstract
Modern life makes people internet-dependents. They want to move connected and care for always getting the best options for connectivity, hoping between providers. Freedom for choosing providers and the business options which these exchanges can offer are the motivations for this chapter. After pointing out some characteristics which make the basics of the current handover technologies, we describe an information infrastructure, based on context and ontologies which can be used to foster an intelligent, efficient and profitable scenario for managing handovers in the Next Generation Networks. Some experiments are described and the potential of using these technologies are evaluated.
