摘要

服务和其他命名资源的发现预计将成为移动自组织网络(manet)可用性的关键特性。不同类型的服务发现体系结构是根据服务协调器(sc)在网络中的实现程度来区分的。sc是拥有中央存储库的节点,用于缓存位于其附近的服务器的服务属性和绑定。本文从服务可用性、消息传递开销和延迟方面描述和研究了不同体系结构的性能。基于大范围的参数对体系结构进行分析和评估。在按需移动网络中,服务发现机制直接影响响应路由协议,路由效果影响评估结果。它还展示了将服务发现与路由发现相结合的好处,特别是在使用响应式路由协议的按需manet中。

Evaluation of Service Discovery Architectures for Mobile Ad Hoc Networks
Discovery of services and other named resources is expected to be a crucial feature for the usability of mobile ad-hoc networks (MANETs). Different types of service discovery architectures are distinguished by the extent that service coordinators (SCs) are implemented in the network. SCs are nodes that hold a central repository for the caching of service attributes and bindings of servers located in its neighborhood. This paper describes and investigates the performance of different architectures in terms of service availability, messaging overhead and latency. The architectures are analyzed and evaluated based on a large range of parameters. The paper also shows that in an on-demand MANET, where the service discovery mechanism will have a direct impact on the reactive routing protocol, the routing effects influence the evaluation result. It also demonstrates the benefits of combining the service discovery with route discovery, especially in on-demand MANETs where reactive routing protocols are being used.
