Abstract

We study the impact of using partial versus full topology in the OLSR (optimized link state routing) protocol for MANETs (mobile ad hoc networks). The core of OLSR is the notion of multi-point relays (MPRs), serving the purpose of reducing the amount of link-state information flooded to nodes in the network, as well as reducing the redundancy in the flooding process. The OLSR protocol specification contains a tunable parameter, MPR coverage, which adjusts the degree of redundancy in both the advertised link-state information, and the links over which the link-state information is advertised. We investigate the impact of assigning various values to this parameter. We further investigate two options for advertising additional link-state information: the "MPR full link-state" option implies that whenever a node is selected to declare any link-state information, it declares all its local link state information; the "full link-state" option states, that all nodes must declare all their local link-state information. Through simulations, we investigate the performance characteristics of OLSR with and without these options.

研究部分拓扑对主动MANET路由协议的影响

我们研究了在移动自组织网络(manet)的OLSR(优化链路状态路由)协议中使用部分拓扑与完全拓扑的影响。OLSR的核心是多点中继(MPRs)的概念，其目的是减少向网络中节点传播的链路状态信息的数量，并减少传播过程中的冗余。OLSR协议规范包含一个可调参数，即MPR覆盖范围，它可以调整发布的链路状态信息和发布链路状态信息的链路中的冗余程度。我们研究了给这个参数赋不同值的影响。我们进一步研究了发布附加链路状态信息的两种选项:“MPR全链路状态”选项意味着，每当选择一个节点声明任何链路状态信息时，它都会声明其所有本地链路状态信息;“全链路状态”选项表示，所有节点必须声明它们所有的本地链路状态信息。通过仿真，我们研究了有和没有这些选项的OLSR的性能特征。
