Security problems for the wireless sensor networks have been exacerbated by the limited energy, power and the size of the sensor devices. In this research paper, the proposed work describes the design and implementation of the deployment of the sensor nodes, master node selection, and dissemination of the authenticated messages into the network to enhance the communication securely among them. Frequent updating of node information in the database that supports the secure communication under very limiting energy. In addition, it selects highly energetic shortest routes that have authenticated nodes for data transmission. Thus, the proposed work improves the performance of the sensor networks by exploiting multiple highly energetic shortest paths with authenticated routers.

INTRODUCTION Wireless sensor node has the capability of sensing, processing, along with the transmission. A sensor system is a deployment, that includes substantial numbers of minute, cost-effective, powered devices that can sense, compute, as well as communicate with different devices when it comes to gather the local data to create wide-spread decisions about a physical environment. WSNs are tends to be resource constrained as they're densely deployed. The number of nodes in WSNs will be placed beyond which will involving ad hoc networks. WSN system topology is consistently transforming, WSNs utilize broadcasting transmission mediums. The devices in these types of applications might be smaller or even huge, as well as the ad hoc networks might be "wired" or even instant i.e wireless. Due to the rigorous energy restrictions associated with large numbers of densely deployed sensor nodes, it requires some sort of selection associated with the network methodology to carry out a variety of network control along with supervision features for example node localization, synchronization along with network stability. The more common redirecting methods possess many shortcomings whenever given to WSNs, which might be generally because of the energy-constrained character. Fig1: Secure data communication
