چکیده (انگلیسی):

Wireless ad hoc networks are used in emergency situations
especially for surveillance and monitoring. The nodes in the ad hoc
networks are self-organized and can accommodate by themselves with the
available resources. The nodes are capable of random movement and
hence there is no fixed infrastructure. The purpose of the ad hoc networks
can be fulfilled only if all nodes cooperate in routing for successful
delivery of packets. But in practice, some nodes may become malicious
so as to preserve their own resources. If the number of such malicious
nodes increases, the performance of the network degrades significantly. In
this study we introduce a novel unique node based clustering and location
key pair based security for the detection of malicious nodes in the
network. The simulation results show that the proposed approach is more
efficient in the detection of malicious nodes.
