A novel approach for detection and avoidance of black hole nodes in wireless data transmission

A novel approach has been introduced in this paper to detect and avoid black hole nodes during formation of reliable path for wireless data transmission. A valid acknowledgement is transmitted to the data packet sending node and its predecessor connected node. A trusted routing table created with valid acknowledgement receiver node. Secure data transmission is dependent upon the trusted routing table. Black hole nodes are required to be discarded from the data transmission. The information about the black hole node is broadcasted to the other nodes of the network to eliminate the uses of false route declaration.
