A solution to the hidden node problem in cognitive radio networks
Tanu Tanu, Dilpreet Kaur · 2017
Hidden node problem is the most common in communication process, where the two nodes that is sender or receiver in the network are not able to see each other and no communication is possible between them. With this problem, a node which wants to send data to other node will not be able to know whether the data has transmitted to the destination or not, which degrades the efficiency of the network. Several existing techniques have been proposed till now in order to resolve these issues in wireless networks but still these methods are not able to get out of it properly and capably. This study implements a new approach by dividing the area of the network in 4 equal sections on the basis of clusters. Then the concept of Cluster Head (CH) is introduced in order to maintain the information or status of the related nodes. The result section shows the proficiency of the proposed work over the traditional work with respect to enhanced accuracy and throughput.
