A Systematic Overview and Comparative Analysis of Service Discovery Protocols and Middlewares

Jawad Hussain Awan, Usman Naseem, Shah Khalid, Nazar Waheed
2020 International Journal of Advanced Computer Science and Applications  
The scalability feature is gained at particular domain while DNS-SD does not provide service discovery to use cases, relax queries. Therefore, it relies on DNS defined messages.  ...  Eight discovery protocols along with their functionalities (such as DEAPspace, DNS-SD, JXTA, RDP, LDAP, CORBA Trader, UDDI and Superstring) are discussed and compared to evaluate the performance and efficiency  ...  Most of the systems have capability of built-in clocks, few uses timestamp like Active badge.  ...
