Comparative Study of Hidden Node Problem and Solution Using Different Techniques and Protocols

Hidden nodes in a wireless network refer to nodes that are out of range of other nodes or a collection of nodes. The authors will discuss a few problems introduced by the RTS/CTS mechanism of collision avoidance and focus on the virtual jamming problem, which allows a malicious node to effectively jam a large fragment of a wireless network at minimum expense of power. They have also discussed WiCCP (Wireless Central Coordinated Protocol) which is a protocol booster that also provides good solution to hidden nodes.
