“…The operating frequencies are chosen in the free industrial, scientific and medical (ISM) band. We consider here the same frequencies used in [23] for comparison purpose which are 868 MHz and 2.4 GHz. For the two frequencies, we have two transmitting bit rates; that is 38.4 kb/s at the 868 MHz and 2500 kb/s at the 2400 MHz frequency.…”

Abstract-Wireless Sensor Networks (WSN) has gained interest in many applications and it becomes important to improve its performance. Antennas and communication performance are most important issues of WSN. In this paper, an adaptive concentric circular array (CCA) is proposed to improve the link between the sink and sensor nodes. This technique is applied to the new HighAltitude Platform (HAP) Wireless Sensor Network (WSN). The proposed array technique is applied for two coverage scenarios; a wider coverage cell of 30 km radius and a smaller cell of 8 km radius. The feasibility of the link is discussed where it shows the possibility of communications between the HAP sink station and sensor nodes located on the ground. The proposed CCA array is optimized using a modified Dolph-Chebyshev feeding function. A comparison with conventional antenna models in literature shows that the link performance in terms of bit energy to noise power spectral density ratio can be improved by up to 11.37 dB for cells of 8 km radius and 16.8 dB in the case of 30 km radius cells that make the link at 2.4 GHz feasible and realizable compared to using conventional antenna techniques.Index Terms-High altitude platforms, wireless sensor network, directional antennas, concentric circular arrays.

“…The cell boundary can be defined by several limits such as the 3 dB or 10 dB power contour. We will apply the 10 dB contour as the cell boundary as in [23] for the purpose of comparison. The antenna model developed by [23] was adopted where the directivity pattern of the aperture antenna was modeled by:…”

In this paper, a concentric circular array (CCA) is designed to provide feasible link between High-Altitude Platform (HAP)-which acts as a sink station-to sensor nodes placed on ground to form a Wireless Sensor Network. The proposed array design technique provides two types of coverage cells namely; wider coverage cell of 30 km radius and another smaller cell of 8 km radius. The link feasibility is examined for practical sensor models at two different frequencies (2.4 GHz and 868 MHz) and two corresponding bit rates (250 and 38.4 kbps) and shows the possibility of communications between the HAP and sensors at all scenarios. The CCA is optimized to improve the power gain inside the cell and reduce the out-of-cell sidelobe radiation using a modified Dolph-Chebyshev CCA. The comparison with conventional antenna models that give the same coverage radii shows that the link performance in terms of bit energy to noise power spectral density ratio can be improved by 11.37 dB for cells of 8 km radius and by 16.8 dB in the case of 30 km radius cells which make the link at 2.4 GHz to be feasible and realizable compared to using conventional antenna techniques.

“…High Altitude Stratospheric Platforms (HASPs) have attracted great attention for many applications such as wireless and mobile data communications, surveillance, wireless data sensor networks, and many others such as digital video broadcasting [1][2][3][4]. HASP has shown in many studies a superior performance when adopted in communication systems compared with satellite and terrestrial communication systems [5] where the high possibility of line-of-sight propagation improves both signal strength and quality of reception. The height of HASP ranges from few kilometres up to 50 kilometres in the stratosphere and can cover several hundreds of kilometres diameter.…”

This paper provides some novel applications of High Altitude Stratospheric Platforms (HASP) for traffic monitoring and management systems. A flying HASP in the stratosphere can provide large area coverage with improved communication performance and is candidate for many applications and scenarios such as flood monitoring, highway traffic monitoring and control, accurate localization of remote accidents, tracking of dangerous wanted vehicles and detection of road faults and floods. The system architecture of HASP for traffic management and control is demonstrated with the proposed applications showing the new provided capabilities and advantages such as localization of vehicles, long endurance operation, controlling of traffic lights over wide area by a single HASP, and efficient traffic data collection.
