Research of Secure Scheme against Data Flooding Attack in Ad Hoc Networks

Abstract

DATA flooding attack is a serious menace for the security of on-demand routing protocol in Ad Hoc networks. In the paper, on the basis of three typical on-demand routing protocols AODV, DSR and TORA, we present a special security scheme against data flooding attack. Then we simulate the scheme on NS2 platform and compare two performance parameters before and after using the scheme: average delay and packet delivery rate. The results indicate that this project is comparatively effective to resist the DATA flooding attack.

Research on Improvement of LEACH Protocol with Heterogeneous Nodes

“…It is divided into a plurality of time slots in the stable data transmission stage that each cluster member communicates to the cluster head in its time slot. The time of the stable data transmission is much more than the time of the establishment stage which save unnecessary energy consumed that the clusters change frequently [6][7][8][9] .…”
