| Summary |
Wireless multi-hop networks have drawn much attention for the future
generation mobile communication systems. These
networks can establish multiple routes from a source node to a
destination node because of flexible construction of network
topology. The transmission by multiple routes has enough capability to
achieve reliable communication because we can expect to obtain
diversity gain by multiple routes. In this paper, we propose the
multi-route coding scheme. At first, we discuss a channel model in
multi-hop networks employing regenerative relay, which we named the
virtual channel model. By using the virtual channel model, a packet is
encoded on multiple routes as follows; a bit sequence of a packet is
encoded and divided into subpackets, and each subpacket is transmitted
on each route. We evaluate its packet error rate performance, and
clarify effectiveness of the proposed scheme. In general, we should
face degradation of a route condition such as the case when a
subpacket does not reach a destination node. Hence, we have to
consider the influence of subpacket loss. We also investigate it,
and show tolerance of the proposed scheme over that. |
