Energy Efficient Secure Routing using Clustering Approach in HWSN

In this paper we have addressed the problem of prolonging life time of a sensor network and securing it with the use of clustering algorithm and intrusion detection system. Prior works suggests that clustering plays dominant role in the death of first node and aggregation plays important role in the death of the last node. We have explore this nature of routing algorithm in present work. In present scenario wireless sensor network have becoming a popular media of monitoring and data gathering. Wireless sensor networks have limited amount of power in it, so it is important that it must be utilized effectively and efficiently. Studies have shown that heterogeneity of sensor node also helps to improve life time of a network. This paper focuses on the improvement in energy utilization with the help of clustering algorithm and results are deduced from them.
