Ad hoc wireless networks have aroused much interest of the scientific community in the last two decades. The provision of Quality of Service (QoS) is a prominent challenge in this research field, since these networks are prone to suffer from instabilities related to wireless medium and mobility. Depending on application, the protocol needs to consider two or more QoS criteria when solving the routing problem. In this context, this work proposes a multicriteria and adaptive framework for proactive routing in order to generate promising compromise solutions by considering critical network quality indicators. Two new methods are proposed—one based on weighted sum method and another based on compromise method (\(\varepsilon\)-constraint)—and compared with the standard weighted sum method. Aiming to map a single final solution, a utility function is proposed to support the definition of the parameters (weights and constraints) of each method. The results show the framework, jointly with the proposed methods, were efficient in promoting significant improvements in the quality indicators investigated in static and mobile scenarios.

在ad-hoc无线网络中使用多准则和自适应框架来改善主动式路由

在过去的二十年中,Ad hoc无线网络引起了科学界的极大兴趣。服务质量(QoS)的提供是该研究领域面临的重大挑战,因为这些网络容易遭受与无线媒体和移动性相关的不稳定。根据应用,协议在解决路由问题时需要考虑两个或多个QoS标准。在这种情况下,这项工作提出了一种用于主动路由的多准则和自适应框架,以便通过考虑关键的网络质量指标来产生有希望的折衷解决方案。提出了两种新方法-一种基于加权和方法,另一种基于折衷方法(\(\ varepsilon \)-constraint),并与标准加权和方法进行比较。为了绘制单个最终解决方案,建议使用效用函数来支持每种方法的参数(权重和约束)的定义。结果表明,该框架与所提出的方法相结合,可以有效地促进静态和移动场景下所研究质量指标的显着改善。
