Efficient Cluster Head Selection and Mobile Sinks for Cluster-Based Wireless Sensor Networks

Madhumathi C S, Guru Siva Kumar T K

Abstract: Security for Wireless Sensor Networks (WSN) is an area that is to be considered in order to protect the data they convey and the location of their members. Energy is a scarce resource in the sensor networks and it has to be used efficiently. To reduce the energy consumption of the nodes, we propose the idea of including an additional node called as mobile sink (MS) in Cluster-based WSN (CWSN). The MS acts like an intermediate between the cluster-head (CH) and the base station (BS). The biggest threat to the sensor networks is the attack of the intruder. To prevent the system from intruder, Intrusion Detection System (IDS) agents are trained about the attacks. The existing scheme just checks the sensor nodes present in the cluster for intruder where as the cluster head is not verified for intruder. The existing cluster-head election is done based on the consumption of energy. We propose adaptive leader election scheme that makes use of an eligibility factor that is calculated based on the remaining battery time and the distance. In CWSN, the mobile sink is dynamic that collects the data from all the CH and then transfers it to the BS. The CH for each round changes based on the adaptive leader election and if any intruder enters into the network at any time, the IDS agents identify the intruder. This change in the proposed scheme uses the energy more efficiently and increases the network lifetime thereby decreasing the false positive rates in the network.
