In this paper, we describe a test of Topology Broadcast based on Reverse-Path Forwarding (TBRPF) [MANET Working Group Draft (2002)] mobile routing protocol compared to Open Shortest Path First-2 (OSPF2) [IETF Network Working Group Draft RFC 2328 (1998)] protocol. The test used a new OPNET model of IEEE 802.11b wireless LAN (W1LAN) that we designed for Mobile Ad hoc Networking (MANET) [IETF Network Working Group Draft (1999)] protocol modeling. Our new model consists of an 802.11b WLAN with enhancements to the physical layer, medium access control layer, and propagation model to facilitate design and study of proposed MANET protocols. Our results indicate the effects of physical topologies on different routing protocols and contrast the difference between a traditional Internet routing protocol (OSPF2) and TBRPF, which was designed specifically for MANET networks. The results should be interesting to planners of new 3G wireless services and to organizations such as military, law enforcement and emergency workers whose missions require wireless mobile networks.
