Abstract
Mobile Adhoc network is a special kind o f wireless
networks. It is a collection o f mobile nodes without having aid of
established infrastructure. Mobile Adhoc network are vulnerable
to attacks compared to wired networks due to limited physical
security, volatile network topologies, power-constrained
operations, intrinsic requirement of mutual trust among all
nodes. During deployment, security emerges as a central
requirement due to many attacks that affects the performance o f
the ad hoc networks. Particularly Denial o f Service attack is one
such severe attack against ad hoc routing protocols which is a
challenging one to defend against in military communication
environments. The proposed model combines
SNAuth-SPMAODV with CCMP-AES mode to defend against
Denial o f Service attack and it also provides confidentiality and
authentication of packets in both routing and link layers of
MANET. The primary focus o f this work is to provide security
mechanisms while transmitting data frames in a node to node
manner. The security protocol CCMP-AES working in data link
layer keeps data frame from eavesdropping, interception,
alteration, or dropping from unauthorized party along the route
from the source to the destination. The simulation is done for
different number o f mobile nodes using network simulator
Qualnet 5.0. The proposed model has shown better results in
terms of total bytes received, packet delivery ratio, throughput.
End to End delay and Average jitter.
