PAISDP: Piggybacking advertisement information based service discovery protocol in pervasive computing environments
Zhenguo Gao · Journal of Jilin University · 2010
Service discovery is the technology of finding needed services in network,which is a key aspect in pervasive computing environments. This paper proposes a novel service discovery protocol,which is named Piggybacking advertisement information based service discovery protocol( PAISDP) . In PAISDP,by means of piggybacking it in the node’s service reply packets,part of advertisement information of a reply node can be propagated along the reply path,which expands its transmission area. Theoretical analysis and Glomosim simulation results demonstrate that PAISDP can reduce the number of service request packets,save the response time,and improve the efficiency of service discovery.
