Moreover, the hidden terminal as well as the exposed terminal problems are handled by CROMA.

  hidden terminals
It is shown that carrier sensing is needed to support collision‐free transmissions in the presence of hidden terminals when nodes transmit RTSs asynchronously.
      
Although there has been considerable work on the performance evaluation of collision avoidance schemes, most analytical work is confined to single-hop ad hoc networks or networks with very few hidden terminals.
      
More importantly, we show that the collision-avoidance scheme can accommodate much fewer competing nodes within a region in a network infested with hidden terminals than in a fully-connected network, if reasonable throughput is to be maintained.
      
MANETs inherit several limitations of wireless networks, meanwhile make new challenges arising from the specificity of MANETs, such as route failures, hidden terminals and exposed terminals.

Ad-hoc networking, though an attractive solution for many applications, still has many unsolved issues, such as the hidden-terminal problem, flexible and prompt access, QoS provisioning, and efficient broadcast service.
      
Among these disadvantages, what we concern most in this paper are energy inefficient consumption and hidden-terminal problem.
      
Here we want to discuss further the hidden-terminal problem aggravated by applying power control and propose our solution.
