Abstract:
Hidden terminal problem is one of the well-known problems when a node is visible from the access point but cannot communicate through it. The problem occurs in ad hoc networks as well as cognitive networks. The clear solution is not discussed in cognitive networks. In this paper, we proposed a method to solve the hidden terminal problem through cloud computing. The idea is that the cloud can store the status of cognitive network, compute, reorganize, and make available the current state of cognitive networks for future decisions. Further, we discussed the role of cloud computing in hidden terminal problems and a solution using the blackboard technology. The simulations were presented to cognitive radio network cloud and discussed the packet transfer and handshaking. The proposed cognitive network model using cloud technologies eliminates the overheads of request to send and clear to send. Further, implementation of cognitive networks through cloud technologies minimizes the problem of sudden entry of primary user.
