A reliable and energy efficient IoT data transmission scheme for smart cities based on redundant residue based error correction coding

Abstract

Cities today face multifarious challenges, including environmental sustainability, and low carbon solutions. Given these trends, it is critical to understand how information and communication technology (ICT) can benefit the future of city-planning process. Internet of Things (IoT) is a futuristic communication concept integrating plethora of interconnected heterogeneous objects forming a large scale smart city system, that is, it can communicate and control other objects over a global network. Hence, devising a fault tolerant mechanism is very important because of construction and deployment characteristics of these smart low powered sensing devices. In this paper, we propose a fault detection and error correction scheme based on redundant residue arithmetic, which provides a low complexity, delay tolerant and energy-efficient data transmission solution. By comparing the proposed method with existing solution in perceived packet loss rate and expected delivery latency, we show advantages of the proposed solution in improving data transmission quality.
