Abstract	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. Low data rate packets can travel longer distance than high data rate packets. Packet sizes of control packets are smaller compared to data packets, so control packets can cover greater distance than other packets. Due to these reasons, communicating nodes find valid paths which data packet cannot cover. This is known as gray zone effect. In our proposed work, we have selected OLSR (proactive), AODV (reactive) routing protocol for analyzing the phenomena. We also propose a simple approach to reduce the performance degradation by limiting the size of application data packets. Keywords— Gray Zone, AODV, OLSR, Lower hop count, Broadcast rate and Unicast rate, Control packets and Data packets, Adhoc Network.
