Statistical Evaluations of Packet Transmission Routes in Wireless Multi-Route and Multi-Hop Networks

In this study, we evaluate the statistical characteristics of packet transmission routes and the hops in wireless multi-route and multi-hop network. Although the wireless network is based on cellar system, we consider the use of forwarding nodes for relaying the packets transmitted by user nodes. The network includes use of multiple routes from a user to base stations. Few researches have been done for statistical evaluations on the network, so far. In our route building method, nodes determine the connectivity based on SNR (signal-to-noise power ratio) of received signals. Our model employs free space propagation power loss model to derive SNR. We observe that the number of routes increases with the number of forwarding nodes and their transmit power. On the other hand, the number of hops per route is saturated with increases of those parameters. We conclude that an adequate selection of the parameters enables to suppress the number of hops
