There has been much research work done on the improvement of adhoc routing protocols to enhance network performances. But in these networks, performance is very much dependent on wireless physical layer where communication is quite complex. The effect of the combination of different routing strategies (protocols) and physical channel properties can vary the network performance up to a great extend. Gray zone effect is one of such effects, which results in high data loss and degradation of performance. Generally, in adhoc networks, broadcast control packets have lower data rate and user packets have same or higher data rates.
