| Abstract(in English) | Wireless multihop networks have been studied for the purpose of solution of digital divide and system capacity enhancement. On the other hand, a network coding scheme has attracted attention as a technology for throughput enhancement. In this paper, we crarify how noise and interference have effects on system throughput performances for two-hop wireless relay slotted ALOHA systems in the cases with and without network coding under asymmetric traffic environments. As a result, the throughput performances of the asymmetric traffic models in the noise and interference environments can be evaluated analytically. In particular, we show the design criterion of the relay transmission probability for maximizing the throughput of systems with network coding. |
