摘要
个人周边智能设备与移动业务的融合促进了服务发现机制的发展,智能设备的增加和移动性也使得现有服务发现机制很难在用户移动当中始终提供有效服务。在对个人周边的异构网络特征分析的基础上,利用组播和信息熔合等技术,提供了一套适用于节点具有群组移动性、异构性的动态网络的可靠的服务发现机制,并且不会消耗过多的系统带宽资源。
The proliferation of mobile devices and pervasiveness of wireless technology have provided a major impetus to the network- based service discovery technologies in wireless and mobile networks. However, existing service discovery protocols fall short of the requirements for accommodating the complexities of the personal environment moving with a user. Based on the analysis of heterogeneous personal environments, a suit of service discovery mechanisms for such environments are proposed to improve the stability and efficiency of the system.
