| Summary |
Wireless multi-hop networks have been much attention for the possibility
of flexible construction of the network topology.
One of the important and interesting techniques for multi-hop networks
is a multi-path routing. By using the
multi-path routing, multiple routes from a source node to a
destination node can be established.
In this paper, we propose the error correcting and diversity combiner
scheme on multiple routes in wireless multi-hop networks to reduce bit errors.
The diversity combiner outputs the likelihood information from the
packets transmitted via multiple routes.
By feeding the likelihood information into the Viterbi decoder,
the diversity gain can be obtained. We evaluate the packet error rate and
the total traffic. As a result, the packet error rate
can be improved. Furthermore, the total traffic can be reduced in the
low Eb/N0 in spite of the traffic increase due to transmission via
redundant routes.
