Abstract
Wireless Sensor Network has been increasingly used for remote monitoring system and its adoption in increasing exponentially for larger application too. However, there are various challenges associated with both resource management and security that roots up when the deployment scale goes massive and distributed in order. The proposed system considers a case study of smart city management where the problems associated with data transmission and security has been addressed. This is carried out using the provisioning of urban environment monitoring system that is an essential system for smart city projects to assure the citizens' better-quality well-being. The scalable and effective urban environment monitoring system requires a seamless transmission of the data from the sensor nodes to the analytics engine. The existing architectures are more designed to suit very specifically the use-cases. As a contribution, the proposed system introduces a cost-effective architecture for environmental monitoring in urban zones of smart city named as a Smart Sensor Surveillance System (4S-UEM). The core idea of the proposed system is to offer a balance between resource efficiency and resilience secure communication in large scale deployment of WSN considering smart city as deployment and assessment area. The proposed system makes use of urban geographical clustering process in order to develop an organized structure of sensor nodes. Different from any existing studies, the proposed system introduces data analytical engine followed by secure routing using gateway. The design of the proposed system is carried out using layered architecture of the communication model targeting towards a cost-effective, energy optimal, and secure data transmission to the analytics engine.
Highlights
Urban environment monitoring (UEM) is an essential requirement for smart city projects [1] [2] [3] for various control mechanism applications
This paper proposes analytical modeling of the design of secure transmission through 4S-UEM to ensure accurate, reliable, and secure communication with optimal coverage
The unified architecture proposed in this paper is named 4S-UEM, keeping in mind that to deploy a smart monitoring system for the urban environment monitoring purpose, the entire region of the urban zone is divided into the urban clusters where a local gateway is chosen smartly and intelligently
Summary
Urban environment monitoring (UEM) is an essential requirement for smart city projects [1] [2] [3] for various control mechanism applications. The intelligent system based on the architecture of the 4S-UEM requires four essential characteristics to be met by the suitable design of the 4S-UEM, and those characteristics are: {Lifetime, Accuracy, Coverage, Reliability}. Another additional requirement apart from these four is secure communication so that the realization of the 4SUEM applications becomes possible in a real-time context.
