Scale Free Wireless Sensor Network Using Topology Modification Strategy

Abstract

Because of the current growth of cyber-assaults, enhancing the strength of Wireless sensor networks (WSN), so we can resist node disasters has emerge as a essential issue. Scale-unfastened WSNs are critical, due to the fact they permit statistics attacks excellently; but, they may be susceptible to malicious attacks, which mainly goal positive critical nodes. To cope with this fault, this paper affords a brand new technique to generate ScaleFree(SF) Network topologies, that examines the limitations in WSNs, which include the conversation variety and the brink at the most node degree. A new topology modification strategy for enhancing the robustness of scale-free WSNs is presented, namely TMSE. Different from previous works, we consider different types of malicious attack into the algorithm design, making the TMSE more resistant to realistic attacks. Besides, TMSE consists of two operations, in which the high degree operation (HDO) changes the network connections among high degree nodes base on the probability of being attacked, and the degree associativity operation (DAO) transforms the network topology into the onion-like structure using its degree–degree correlation
