In very dense networks, the performance of message broadcasting highly depends on the propagation conditions. In this paper, we investigate the effect of the path loss exponent in relation to the carrier sense threshold setting and the traffic intensity. We present a new analysis of the hidden node area in a broadcast network and compare broadcast outage probabilities for various traffic loads and carrier sense ranges. According to our model, the propagation environment (in particular the path loss exponent) has a major influence on performance. The traffic load and carrier sense range also affect throughput. A large attempted traffic load per carrier sense is preferred, since this gives the best performance.
