Transmission of Data in Wireless Sensor Network using Adaptive Clustering

Sensor networks present unique opportunities for a broad spectrum of applications such as industrial automation, situation awareness, tactical surveillance for military application and environmental monitoring, chemical/biological detection etc. Sensor Network can monitor ambient condition such as temperature, sound, light and others. Information is collected from many sensor devices for further consumer application in the Sensor Network. For selecting a cluster head, k-means algorithm will be used to find the cluster centre. For hop to hop packet forwarding, AODV protocol has been used at network layer. All the simulations of the proposed idea will be simulated on Berkeley's ns2 network simulator and the performance of the proposed scheme has been evaluated. Due to wireless nature of sensor network, secure data transmission is a major issue for wireless sensor network. Clustering is a technique which increases network lifetime and reduces power consumption of sensor nodes in WSN. In this paper, we study an authenticated way to data transmission for cluster based WSN. Our results show that performance of proposed protocols is better than existing secure protocols.
