| Summary |
The multiple-route packet combining (MRPC) is a diversity
combining and error correction scheme for wireless multihop networks. In
this scheme, multiple replicas of a coded packet are transmitted along
different disjoint routes from a source node. These replicas are
received, combined and decoded by the destination. If a conventional
multipath routing protocol, such as MDSR, is employed, smaller hop
routes tend to be selected to transmit packets. However, the performance
of MRPC depends on the packet reception probability and the bit error
rate of each route. It is therefore expected that the performance
improves if these statics are utilized as a route selection metric. In
this paper, we compare the packet error performance of MRPC for
different route selection metrics. Three different metrics are
considered, that is, the log-likelihood ratio (LLR), the packet
reception probability, and the number of hops of a route. From the
performance comparison, we show that LLR is the best metric when packet
decoding errors are dominant over packet losses. |
