| 摘 要： | 提出了普适环境下一个新的服务发现协议:PAISDP(Piggybacking advertisement infor-mation based service discovery protocol),即在服务发现的回复包中携带回复节点的部分广播信息,使得广播信息能随着回复包在回复路径上传播,扩大了广播信息的传送范围。理论分析和仿真实验表明:PAISDP减少了服务请求包数量,降低了服务响应时间,提高了服务发现效率。 |

| Abstract: | 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. |
