Abstract

Conventional routing protocols used in wireline and wireless networks are not designed to operate in an autonomous (or ad hoc) wireless local area network (AWLAN) environment with asymmetric (i.e. unidirectional) links. This paper presents the design of a routing protocol called source-initiated adaptive routing algorithm (SARA), for AWLAN environments that may contain asymmetric links. To allow efficient operation in a symmetric network while ensuring correct operation in asymmetric networks, SARA supports two different modes of protocol operation: one optimized for symmetric networks and the other providing additional capabilities needed for operation in asymmetric networks at a higher cost. The ability of SARA to adapt its mode of operation and optimize its execution for each network environment is one of its major advantages and distinguishes it from existing routing protocols for, wireless networks. Furthermore, within each of its operating modes, SARA supports best-effort as well as policy-based routing.

自主无线局域网的源发起自适应路由算法

有线和无线网络中使用的传统路由协议不适合在具有非对称(即单向)链路的自治(或特设)无线局域网(AWLAN)环境中运行。本文针对可能包含非对称链路的AWLAN环境，提出了一种称为源发起自适应路由算法(SARA)的路由协议设计。为了允许在对称网络中高效运行，同时确保在非对称网络中正确运行，SARA支持两种不同的协议运行模式:一种是针对对称网络进行优化的，另一种是以更高的成本提供非对称网络中运行所需的额外功能。SARA能够根据不同的网络环境调整其操作模式并优化其执行，这是其主要优势之一，并将其与现有的无线网络路由协议区分开来。此外，在每个操作模式中，SARA都支持尽力而为和基于策略的路由。
