Effectiveness of AODV Protocol under Hidden Node Environment [chapter]

Ruchi Garg, Himanshu Sharma, Sumit Kumar
2010 Communications in Computer and Information Science  
IEEE 802.11 is a standard for mobile ad hoc networks (MANET), implemented with various different protocols.  ...  To avoid the collision and interference the MAC protocol has only two solutions, one, to sense the physical carrier and second, to use the RTS/CTS handshake mechanism.  ...  CONCLUSION In the IEEE 802.11 standard, the RTS/CTS mechanism is only optional.
