AN EFFECTIVE ATTACK ELIMINATION METHOD FOR TOP-K QUERY PROCESSING IN MANETS
Journal Title: Elysium Journal of Engineering Research and Management - Year 2016, Vol 4, Issue 6
Abstract
The query processing in mobile ad hoc network (MANETs) is optimized using top K-query concepts but this process in affected by the presence of malicious nodes in the environment where it may induce unrelated information. The presence of false date will not let to produce accurate result during query processing. In this paper, an attempt is made to discover the nodes that are malicious in nature, there are two ways of attack is possible one in Data Replacement Attack (DRA) and another one is False Notification Attack (FNA).In the first case one or more nodes will induce unrelated information in to the network, in second case the trusted node will send false information to the network. The proposed method detects these attacks by using score values in top k query processing, in which nodes reply with data items and their score value are used to identify the data replacement attack in network. After detecting the attack based on the malicious node information query issue node group the node in order to identify the false notification attack in network, which improves the accuracy of top k result for malicious node identification in MANET.
