Performance evaluation of a wireless ad hoc network: flexible radio network (FRN)

In an ad hoc wireless network system, wireless terminals can autonomously construct a network and directly communicate with each other without using a wired network. A flexible radio network is one of the ad hoc wireless network systems which has been operational in recent years. In the flexible radio network, an original communication protocol is implemented to obtain reliability of communication. We evaluate the performance by means of simulations for the data-link protocol and routing protocol of the flexible radio network. We first show the performance when system parameters are changed to examine how these parameters affect the system performance. Furthermore, we investigate the performance improvement by changing the network configuration.
