Protecting the data from intruders and increasing the network lifetime is a major constraint in wireless sensor network. The lifetime of the network is determined by the amount of energy consumed by each node. In order to increase the network lifetime and protect the data, the security based clustering algorithm is proposed. It construct the clusters to reduce the energy consumption among the sensor nodes in which the cluster head collects and aggregate the data from the cluster members. A special node MDC (Mobile Data Collector) collects and aggregates the data from cluster head and forwards them to base station.
