摘要：

服务发现协议是移动Ad-hoc网络中的关键技术,通过服务发现在移动Ad-hoc网络中查询和发现网络服务,这类协议通过自动定位确定网络节点的位置,寻找相应的服务。在移动Ad-hoc网络中,网络节点通常是变化和移动的,由于其多变性,网络的拓扑结构具有不确定性,难以在网络中进行有效的服务发现。针对这些问题,一些相应的解决方法相继被提出,这些方法可以分为基于应用层和网络层的服务发现,但各自在网络资源问题上还不能得到有效解决。基于各类协议的不同特性,多种协议并存是理论上可行的方法,但由于多协议之间存在异构性,多协议并存的方式将导致内存消耗和网络信息流量过大。文章采用一种基于构件的服务发现框架,通过可配置的和动态可重构的中间件,可以在多协议环境中进行操作,较好地处理了协议间的异构性,增强了框架的可配置性和重构性。

Abstract:

Service discovery protocol is the key technology of mobile Ad-hoc network. This kind of protocol can find the location of the nodes and service automatically. The network topology is uncertain, and the service is difficult to be found in the network because the nodes are usually changed and moved in mobile Ad-hoc networks. To address these problems, some corresponding solutions are put forward. These methods can be divided into service discovery based on application layer and network layer, but they cannot effectively work. Based on the different characteristics of different protocols, it is feasible that these protocols are adopted in combination. However, multi protocol will lead to the problem of memory consumption and network information flow because of the heterogeneous nature of multi protocol. In this paper, a kind of service discovery framework based on component is adopted, which can be operated in a multi protocol environment. This fixed the heterogeneity problem of multi protocol and the framework is configurable and reconfigurable.
