Leader Election for Intrusion Detection Systems

The Mobile Ad hoc Networks (MANETs) have no fixed chokepoints/bottlenecks whereIntrusion Detection Systems (IDS) can be deployed. Each node should run its IDS. As the nodes in MANET are battery limited, one node per cluster is elected as leader to run IDS for all the nodes in the cluster. The leader is elected based on the residual energy of each node that is sufficient to run IDS.


It is too much of resources are wasted for the implementation of the intrusion detection scheme for every node. Hence nodes are grouped into clusters and cluster head is elected to serve other node in the network, where as a selfish node with maximum resources are not nominated for cluster head selection, because of self interest to save its own power.


To ensure security, and to detect the intrusion in Mobile Ad hoc networks selects a leader (cluster head) is selected from the 1hop cluster as contains most resources. A mechanism based design theory is a solution; to avoid the issues arise due to optimal collection of leader and performance overhead. Nodes provide incentives in the leader election process by VCG mechanism for preventing the nodes from exhibiting the selfish behavior.

Solution in NS2

  • A leader (cluster head) is selected from the 1hop cluster that contains most resources (energy) in ns2.

  • Network Simulator (ns-2) version is used and the evaluation metrics are calculated to increase the number of alive nodes and also to effective detection of misbehaving nodes with high accuracy and also with average cluster size is achieved in MANET.
