Abstract:

Abstract. Networks are vital in today's world. Design and configuration of networks have made the special considerations necessary for its various aspects such as security, integrity, scalability and cost. Malicious nodes on the network must be identified to enhance the resistance of network. Thus, detection of malicious nodes is critical in the networks .The concepts are presented in this article such as cross talking and black holes and studied networks are under the influence of random and targeted attacks. Also some algorithms have been developed to assess the vulnerability value and networks analysis against random and targeted failures in terms of establishment and detection of black holes and measurement of cross talking value in order to analyze the complex networks by help of above mentioned   implications. The proposed strategies will allow us to design the networks and to reduce the threshold to secure them for all modes of problems (targeted and random).
