Robust and Secure Data Fusion Algorithm Based on Intelligent Sensing in Wireless Sensor Networks

الملخص EN

Presently, the wireless sensor network (WSN) plays an important role in smart farming.

However, due to the limitation of wireless sensor network resources, the time and space correlation of data acquisition is strong.

In order to reduce the number of nodes participating in data compression, the robust and secure data fusion algorithm based on intelligent sensing is proposed.

The algorithm can divide the whole network into many clusters.

In order to maintain energy balance of nodes in the cluster, the probability of each node in each cluster participating in each round of data collection is computed according to the residual energy of the node.

On the sink node, the number of sampling rounds of joint reconstruction of collected data is designated according to the application requirements and reconstruction accuracy requirements, and the number of nodes participating in is further reduced.

The simulation results show that the number of nodes participating in the data collection of the proposed scheme in this paper is lower than that of the ordinary intelligent sensing LEACH data acquisition scheme.

Meanwhile, the proposed scheme can dramatically extend the network lifetime.

This paper provides an insight into various needs of WSN used in agriculture and challenges involved in the deployment of WSN.
