Abstract :
The author considers the possibility of obtaining performance gains by using channel power sensing in the channel access protocol of a terrestrial spread-spectrum packet radio network as a generalization of the CSMA (carrier-sense multiple-access) protocol of narrowband networks. Channel load sensing is viewed as a method of estimating the interference at the receiver based on the interference measured at the transmitter. To do this, a bivariate probability distribution function of the interference at the two locations is required. The probability of packet success is then determined. Since it is difficult to evaluate numerically, a program was written to simulate it. The author gives simulation results for the case of a random network
