“…The problem of computer vision based system still remains unsolved and security problems [31]. In contrast to the existing work which can only detect the number of available parking spots on roads, the solution can be extended to detect parking lots occupancy in various regions such as grass, brick and mud parking spots.…”

An improvement in technology is linearly related to time and time-relevant problems. It has been seen that as time progresses, the number of problems humans face also increases. However, technology to resolve these problems tends to improve as well [1]. One of the earliest existing problems which started with the invention of vehicles was parking. The ease of resolving this problem using technology has evolved over the years but the problem of parking still remains unsolved. The main reason behind this is that parking doesn't only involve one problem but it consists of a set of problems within itself. One of these problems is the occupancy detection of the parking slots in a distributed parking ecosystem. In a distributed system, users would find preferable parking spaces as opposed to random parking spaces. In this paper, we propose a web-based application as a solution for parking space detection in different parking spaces. The solution is based on Computer Vision (CV) [2] [3] and is built using the Django framework written in Python 3.0. The solution works to resolve the occupancy detection problem along with providing the user the option to determine the block based on availability and his preference. The evaluation results for our proposed system are promising and efficient. The proposed system can also be integrated with different systems and be used for solving other relevant parking problems.

“…RBLE uses a simple BFSK modulation, which inevitably did not form an optimal match with the commodity BLE receiver. Pulse shaping is a missing piece in many SoA backscatter systems [10,17,21,22,34,35,[37][38][39]. We believe that high bandwidth efficiency brought by pulse shaping or new modulation schemes has a positive effect on improving the communication reliability of the backscatter systems that are trying to communicate with commodity radios.…”

“…X-Tandem[38] presents a multi-hop backscatter solution that works for commodity WiFi devices. LTE backscatter[10] presents a system that leverages the continuous LTE traffic for pervasive backscatter communication. Multiscatter[13] tag can identify various exciting signals (WiFi, BLE, and Zig-Bee) in a low-power way and leverage these signals to convey tag data.…”

The communication reliability of state-of-the-art Bluetooth Low Energy (BLE) backscatter systems is fundamentally limited by their modulation schemes because the Binary Frequency Shift Keying (BFSK) modulation of the tag does not exactly match commodity BLE receivers designed for Gauss Frequency Shift Keying (GFSK) modulated signals with high bandwidth efficiency. Gaussian pulse shaping is a missing piece in state-of-the-art BLE backscatter systems. Inspired by active BLE and applying calculus, we present IBLE, a BLE backscatter communication system that achieves full compatibility with commodity BLE devices. IBLE leverages the fact that phase shift is the integral of frequency over time to build a reliable physical layer for BLE backscatter. IBLE uses instantaneous phase shift (IPS) modulation, GFSK modulation, and optional FEC coding to improve the reliability of BLE backscatter communication to the commodity level. We prototype IBLE using various commodity BLE devices and a customized tag with FPGA. Empirical results demonstrate that IBLE achieves PERs of 0.04% and 0.68% when the uplink distances are 2 m and 14 m respectively, which are 280x and 70x lower than the PERs of the state-of-the-art system RBLE. On the premise of meeting the BER requirements of the BLE specification, the uplink range of IBLE is 20 m. Since BLE devices are everywhere, IBLE is readily deployable in our everyday IoT applications. CCS CONCEPTS• Networks → Network design principles; Sensor networks.

“…Backscatter technology aims to use an ambient signal (like WiFi [ 209 ] or LTE [ 210 ]) for communication from a tag-device through passive radio using a low-power reflective RF switch and a passive antenna towards a receiver. Zheng et al [ 211 ] propose using backscatter to enhance a Wireless Powered Communication Network collaboration between two devices that first harvest wireless energy from a Hybrid Access Point (HAP) and afterwards transmit their information to the HAP.…”

The issue of energy balancing in Wireless Sensor Networks is a pivotal one, crucial in their deployment. This problem can be subdivided in three areas: (i) energy conservation techniques, usually implying minimizing the cost of communication at the nodes since it is known that the radio is the biggest consumer of the available energy; (ii) energy-harvesting techniques, converting energy from not full-time available environmental sources and usually storing it; and (iii) energy transfer techniques, sharing energy resources from one node (either specialized or not) to another one. In this article, we survey the main contributions in these three areas and identify the main trending topics in recent research. A discussion and some future directions are also included.
