Identification of Malicious and Liar Nodes by Query Processing In Manets
Authors(2) :-R. Gangadevi, T. Ravichandran
Mobile Ad-hoc Networks (MANETs) is a collection of mobile nodes sharing a wireless channel without any centralized control (or) established communication backbone. MANETs require fundamental changes to network routing protocols. These are characterized by the mobility of nodes, which can move in any direction and at any speed that may lead to arbitrary topology and frequent partition in the network. In the existing method, the malicious nodes are identified based on the grouping. In MANETs, if a normal node becomes an attacker, the malicious node tries to disrupt the operations of the system. The main drawback in the above existing method that it doesn’t address the critical Liar Nodes (LNs) responsible for the network in security. In this proposed work, malicious node are identified based on the top-k-query processing methods and it is also designed to locate and identify LNs by the False Notification Attacks (FNA) using the Dynamic Source Routing (DSR) reactive routing protocol and to prevent the liar nodes from performing False Notification Attack (FNA). So that the message can be sent with more security by using the Rivest Shamir Adleman (RSA) Algorithm and Secure Hashing Algorithm 1(SHA1) methods and also with less power, thereby increasing the battery life. To analyse the following parameters such as Throughput and packet loss were simulated through Network Simulator-2 (NS-2). In the proposed work, the output produced promising results to identify and eliminate the LNs, and thus reducing the number of unwanted nodes thereby improving security due to unwanted nodes using majority of the network performance and metrices.
