The aim of this research work is to design a smart city simulator. The proposed simulator contains the 3D model of several locations of the city with each location equipped with multiple types of virtual sensors node. The virtual sensors mainly include Noise Sensor, Air Pollution, Ultrasonic Sensor, Humidity Sensor, Temperature Sensor and Video Camera. These sensors continuously monitor and collect...
The video captured by different visual sensor in a visual sensor network is first compressed using the block-based compressive sensing algorithm. All the videos are encoded independently at different sub-rates and transmitted to a host workstation for reconstruction. Then, the proposed multi-phase joint reconstruction framework is applied to improve the reconstruction of lower subrate videos. In this...
Field-Programmable Gate Arrays (FPGAs) have turned out to be a well-liked target for implementing cryptographic block ciphers. In this research work, recently proposed 64 bit Secure Force (SF) algorithm is implemented on an FPGA based full loop-unroll architecture. The proposed FPGA implementation of Secure Force yields a throughput of 2.3 Gbps for encryption, 2.6 Gbps for decryption, and 3.43 Gbps...
In this paper, a multi-view image compression framework for the Visual Sensor Network (VSN) is proposed that involve the use of Block-based Compressive Sensing (BCS) and multi-phase joint decoding. In the proposed framework, one of the sensor nodes (encoder) is configured to serve as the reference node, whereas the others as non-reference nodes. The images captured by the reference and non-reference...
Since devices in the Wireless Sensor Network (WSN) are usually small in size, resource constraint is one of the critical issues that needs to be taken into consideration. In this paper, a low-complexity symmetric cryptographic algorithm, denoted as Secure Force (SF), is proposed. It is developed based on the Feistel structure, and the encryption part can be implemented by using a simple architecture...
