Abstract

In multi-hop networks, conventional forwarding along a unicast route forces the data transmission to follow a fixed sequence of nodes. In previous works, it has been shown that widening this path to create a corridor of forwarding nodes and applying OFDMA to split and merge the data as it travels through the corridor towards the destination node leads to considerable gains in achievable throughput compared to the case of forwarding data along a unicast route. However, the possibility of applying spatial reuse in such kind of networks has not been investigated. In this paper, three different schemes for spatial reuse in multi-hop OFDMA networks applying corridorbased routing are presented and compared to the case without spatial reuse. From simulations it can be seen that spatial reuse increases the throughput. For different signal-to-noise ratio regions, different schemes perform best due to the way the interference is handled by the schemes.
