A Review on Data Collection Strategy and Power Consumption using Mobile Vehicles and UAVs In Smart Cities

Cities can identify trends and needs by analyzing data from IOT devices and sensors. Wireless sensor networks (WSNs) are generally used in numerous field of interest to detect phenomena, process the detected data and take appropriate actions. Due to the limited sources of stationary sensor nodes, WSNs must work with mobile robots such as unmanned aerial vehicles (UAVs) and Unmanned Ground Vehicles(UGVs) in their development. Consequently, it is necessary to maintain the energy efficiency of UAVs since they are approved by data centers so they must be deployed and charged frequently. Researchers worked on this area and came across various schemes for efficient data collection with minimal energy usage. This paper gives a structured and extensive review of different schemes proposed by different authors around the globe. This paper also evaluates the datasets utilized by different researchers for data collection method. Finally, the challenges involved in data collection method and power consumption are highlighted in conclusion section. We have also listed the future work in conclusion section.
