摘要:

移动自组织网络(MANET)是一种非集中式的、多跳的无线网络,缺乏公共的基础设施,因此需要自组织。移动自组网中最大的挑战是在通信节点之间找到一条路径,这就是移动自组网的路由问题。生物启发的技术,如蚁群优化(ACO)已被证明是非常适应在其他问题领域,已被应用到移动自组网路由问题,因为它形成了一个很好的适合的问题。这些生物系统的一般特性,其中包括它们的自我组织,自我修复和本地决策的能力,使它们适合在MANNETWORK路由。本文讨论了几种基于蚁群算法的协议,即AntNet、混合蚁群算法(AntHocNet)、基于蚁群优化的路由算法(ARA)、改进的移动自组网蚁群优化路由算法(PACONET)、基于需求距离向量的蚁群优化算法(Ant-AODV)和基于ACO的动态源路由(Ant-DSR),并根据服务质量(QoS)参数来确定它们的性能,例如端到端延迟和数据包传输率。我们还比较他们与著名的协议,ad hoc按需距离矢量(AODV)和动态源路由(DSR),随机路点移动模型的基础上。仿真结果表明,这种生物启发的方法有助于提高QoS参数。

英文摘要:

A mobile ad hoc network (MANET) is a non-centralised, multihop, wireless network that lacks a common infrastructure and hence it needs self-organisation. The biggest challenge in MANETs is to find a path between communicating nodes, which is the MANET routing problem. Biology-inspired techniques such as ant colony optimisation (ACO) which have proven to be very adaptable in other problem domains, have been applied to the MANET routing problem as it forms a good fit to the problem. The general characteristics of these biological systems, which include their capability for self-organisation, self-healing and local decision making, make them suitable for routing in MANETs. In this paper, we discuss a few ACO based protocols, namely AntNet, hybrid ACO (AntHocNet), ACO based routing algorithm (ARA), imProved ant colony optimisation routing algorithm for mobile ad hoc NETworks (PACONET), ACO based on demand distance vector (Ant-AODV) and ACO based dynamic source routing (Ant-DSR), and determine their performance in terms of quality of service (QoS) parameters, such as end-to-end delay and packet delivery ratio, using Network Simulator 2 (NS2). We also compare them with well known protocols, ad hoc on demand distance vector (AODV) and dynamic source routing (DSR), based on the random waypoint mobility model. The simulation results show how this biology-inspired approach helps in improving QoS parameters.
