OPTIMISED SECURITY FRAMEWORK BASED ON TIME STAMP FOR DOS ATTACKS IN WIRELESS SENSOR NETWORKS
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 2015, Vol 4, Issue 1
Abstract
Network performance always dependent on the perfect flow of the data processing packets in network but with attacks in network, performance halted a lot or just degraded at times. Denial of service attack is one of the most dangerous and real time attack which could slow down every service and network, especially when applied to ad-hoc networks such as wireless sensor networks. In this paper we designed optimized security framework for detection of dos attacks. This research focused on detection of time based denial of service attacks which work on timely bases and are not detected by normal process. The time difference between two nodes and the time stamp period variation is calculated. If two nodes are showing variation which tends to more timestamp period then it considered to be malicious node. Our proposed work provides better results in term of throughput recovery by avoiding mechanism.
