Abstract EN
Network coding (NC) is significant for the spectral efficiency promotion of the multiple-source multiple-relay wireless sensor networks (WSNs).
However, the existing scheme ignored further exploitation of the communications between relays.
To address this issue, a relay ordering algorithm based on finite field NC (FFNC) is proposed in this paper.
In the scheme, the relays who initially fail to decode from sources are kept listening and searching for the opportunity to decode the signals from other relays, so as to recover the failure links.
The outage probability of the scheme and the corresponding lower bound are theoretically deduced under two-source two-relay assumption.
Moreover, the scheme is proved to own the merit of diffusion effect, which makes the diversity improvement more efficient by simply increasing the relay number in the network.
Simulation results correspond well with the analysis and demonstrate that the proposed scheme always outperforms FFNC in outage behavior and attains more opportunities to supply full diversity for the network.
Moreover, it shows that the diffusion effect enables this scheme to be very suitable for the multiple-relay WSN.
