Abstract: The Wireless Sensor Networks (WSNs) are composed of sensor nodes and sink nodes, and the network of sensor nodes is energy constrained, so the reliability of the WSNs is closely related to the energy of the nodes. According to the characteristics of the WSNs, this paper gives the concepts of the reliability and transmission reliability in WSNs, and analyses the energy consumption of sensor nodes in cases of data fusion and no data fusion. Additionally, we get the function relationship between reliability probability and time when WSN nodes are in normal working condition. Furthermore, by the simulation technology, we evaluate the reliability of the WSNs and the transmission reliability method of the entire network associated with the different level of energy. Finally, we propose the algorithm of transmission reliability model in the process of wireless transmission with energy restrictions.

Keywords: WSNs; wireless sensor networks; energy modelling; data fusion; node reliability; transmission reliability; energy consumption; simulation.
