摘要：In Wireless Sensor Networks (WSN) sensor nodes are deployed in their sensing areas for the purpose of sensing, monitoring or detecting physical phenomena, and providing measurements which help decision makers in various related applications that WSNs are used for. However, the appropriate network design plays the main role which increases the advantages of using very limited resources network such as WSN. WSNs are operated on batteries where their lifetime needs to be extended in order to meet the sensor nodes functions. The sensor node in WSNs cannot be installed with more than one single antenna for reducing the power consumption. However, Virtual Multiple-Input Multiple-Output (V-MIMO) technology has the benefits of increasing the transmission range, the throughput, and reducing the power consumption of WSNs. In addition, the height of sensor node deployment in the sensing field is usually neglected in the network design, which we believe, in this paper, that the height of the sensor node has a great impact on reducing the power consumption of WSNs, especially in multi-hop transmission scenarios, which are based on intercluster and intracluster data communication. Thus, in this paper, we propose WSN deign which is based on the convergence between the V-MIMO technology and the height strategy of nodes deployment in order to increase the WSNs performance. The simulation results show that the proposed convergence technique has high performance in terms of the network lifetime, the received signal strength, the packets reception ratio and the energy efficiency.
