移动自组织网络(MANET)通常是为临时场景而创建的。在这样的场景中，节点处于移动性，高效的路由是一项具有挑战性的任务。在本文中，我们提出了一种适应这种变化场景的自适应跨层多路径路由协议。我们的路由机制根据应用程序的类型进行操作。对于简单的应用，该协议的灵感来自于传统的按需路由协议，它使用默认参数搜索从源到目的地的最短路径。在多媒体应用的情况下，所提出的机制考虑了能够提供更高的数据速率和更低的丢包率的这类路由。对于那些需要安全的应用，建议的机制会搜索本质上比其他路径更安全的路径。所提出的路由方案采用跨层方法，使不同的参数能够在整个协议栈之间交换，从而在网络层更好地进行决策。我们的方法在我们模拟和测试的各种场景中都是高效和容错的。
Mobile ad hoc networks (MANETs) are generally created for temporary scenarios. In such scenarios, where nodes are in mobility, efficient routing is a challenging task. In this paper, we propose an adaptive and cross-layer multipath routing protocol for such changing scenarios. Our routing mechanisms operate keeping in view the type of applications. For simple applications, the proposed protocol is inspired from traditional on-demand routing protocols by searching shortest routes from source to destination using default parameters. In case of multimedia applications, the proposed mechanism considers such routes which are capable of providing more data rates having less packet loss ratio. For those applications which need security, the proposed mechanism searches such routes which are more secure in nature as compared to others. Cross-layer methodology is used in proposed routing scheme so as to exchange different parameters across the protocol stack for better decision-making at network layer. Our approach is efficient and fault tolerant in a variety of scenarios that we simulated and tested.
