Abstract
Security is one of an important factor to be consid ered seriously in wireless sensor networks. In WSN, in many ways intrusion may occur, in the past decades there is no perfect IDS, without any wasting of resources like time, energy, cost and number of phy sical items. The main objective is to ensure the se curity and improve the quality of network by applying a Le ader based intrusion detection system in the Wirele ss Sensor Network (WSN). Here, we are focusing on the attack known as sinkhole attack which is considered as the biggest threat in wireless sensor network wh ich spoils the complete communication and a data lo ss between a pair of nodes as source node and a destin ation node. In order to provide a complete solution to detect and avoid sinkhole attack a Leader Based Int rusion Detection System (LBIDS) is proposed. In thi s approach a leader is elected for each group nodes w ithin the network, region wise and it do compares a nd calculates the behavior of every node, logically ex ecutes our detection module and monitors each node behaviour within the cluster for any sinkhole attac k to occur. When a node gets detected as a compromised node, it informs that nodes status to the other lea der within the WSN, so all the leaders in the netwo rk knows about the sink hole node information and the leaders stop communication with sinkhole Node.

We are focusing on the attack known as sinkhole attack which is considered as the biggest threat in wireless sensor network which spoils the complete communication and a data loss between a pair of nodes as source node and a destination node
The performance of the proposed approach is proved by a number of iterative simulations done in Network Simulator 2, by changing the number of
In our approach we improved the performance of the system by means of energy efficiency and intrusion detection rate
Summary
A light weight intrusion detection system is designed to detect the sinkhole attack within the sensor network which uses the leader election based approach for executing instruction detection system in WSN (Mohammed et al, 2011) helps to overcome limited energy problem, by dividing the MANET into a set of one hop clusters where each node belongs to at least one cluster. The nodes in each cluster elect a leader node (cluster head) to serve as the IDS for the entire cluster This approach aims to reduce the overall resource consumption of IDSs in the network (Li et al, 2008). The rest of this study is organized as follows: Section 2 presents the detailed leader based intrusion detection mechanism, sinkhole attack and its remedies, its routing algorithm.
