Chapter 3 - Why IP for Smart Objects?

Abstract

Smart object networks and their applications give rise to challenges both at the node and the network level. To meet these challenges a network architecture is required that is interoperable across a wide range of communication technologies, that evolves as the field of smart objects evolves, and that is scalable enough to meet the challenges imposed by large-scale smart object networks while lightweight enough for the node-level resource constraints. This chapter focuses on how IP architecture meets these goals while providing unprecedented interoperability with existing networks, applications, and services. Interoperability is a predominant characteristic of the IP architecture. It is interoperable because it runs over link layers with very different characteristics, providing interoperability among them and because IP provides interoperability with existing networks, applications, and protocols. Standardization plays a large part in the success of IP's interoperability. IP is standardized by an established standardization organization that provides mechanisms through which new standards are reviewed and vetted. This process puts a large amount of effort into ensuring that the mechanisms and protocols proposed as standards can be efficiently implemented. From the outset, the IP architecture was designed to allow application layer protocols and mechanisms to evolve independently of the underlying network protocols and mechanisms. The IP architecture has also been thoroughly field-proven regarding scalability through the use of IP over the public Internet.
