The characteristics of Cooperating Object applications are quite different from traditional wireless and wired networks. There are critical factors that influence the architectural design and protocol development of Cooperating Object applications that introduce some stringent constraints. Moreover, the constraints for a Cooperating Object application domain may be quite different from another one. For example, security requirements in health and security applications can be more critical than in a home application scenario. Therefore, a onesize-fits-all approach does not work for Cooperating Objects. Additionally, there is a need for application categorisation in order to be able to identify common requirements.

Cooperating Object applications can be classified in many different ways since each application has common features with others such as mobility, scalability, heterogeneity, robustness, fault tolerance, etc. In this study, application domains that have a social and economic impact in society are used as the basis of classification. These domains are:

• Control and automation
• Home and office
• Logistics
• Transportation
• Environmental monitoring
• Healthcare
• Security and surveillance
• Tourism
• Education and training
