Enhanced Algorithm for Reduction of Blackhole’s Re-Judgment Delay for Realtime Traffic in Mobile Adhoc Network
Sarah Florence Massae and Joseph Chrisant Pengo, National Institute of Transport, Tanzania
Abstract
Mobile Ad-hoc Network (MANET) is a prominent technology in wireless communication in which mobile nodes operate in a distributed manner without having central control devices; This lack of control over network devices and over changing topology aspects of the network allows malicious nodes gain opportunities to join the network. The blackhole attack is one of the security risks that increases the network overhead. In this attack, the malicious node advertises itself as having the shortest path to the destination and falsely replies to the route requests, and drops all receiving packets. Therefore, the paper proposes a trust-level based re-judgment algorithm. Experiments were set up in the NS3 networking simulation tool. Simulations results showed that the proposed trust-level based re-judgment algorithm improves network throughput and packet delivery rate by 82.8% and 146.6 Kbps respectively. Also, reduces the end-to-end delay by an average of 24.17 milliseconds.
