In [15], approximations for the channel capacity of opportunistic cooperative multiple relay networks over Rayleigh fading channels under optimal simultaneous power and rate (OSPR), optimal rate with constant power (ORCP), and truncated channel inversion with fixed rate (TCIFR) were investigated.

The analytical results with multiple relay network topology are illustrated as Fig. 7.

In this paper, the novel extension of analog network coding based on space-time coding technique in multiple relay network under different fading scenarios is presented.

Second, under the single or multiple relay network environment and mobility of sensors, the selective characteristics of time and frequency domain were studied.
