A performance investigation on IoT enabled intra-vehicular wireless sensor networks

Abstract

The concept of Internet of Things (IoT) can be utilised in vehicles, since the number of sensor nodes in vehicles is rising tremendously because of the uplifting demand of applications for security, safety and convenience. In order to establish the communication among these nodes inside a vehicle, a controller area network with wired architecture provides a prominent solution. However, this solution is not flexible because of the architectural complexity and the demand for a large number of sensors inside the vehicle; hence wired architectures are replaced by wireless ones. Moreover, scalability will be an important issue while introducing the IoT concept in Intra-Vehicular Wireless Sensor Networks (IVWSNs). In this paper, a comprehensive performance investigation on the IoT enabled IVWSNs (IoT-IVWSNs) to be carried out in order to address this issue. The overview of the IoT-IVWSNs with a comparative study of the existing technologies and the design challenges for such network are provided. The link design between an enddevice and the control unit is analysed, and the performance of the network has been investigated and some open research issues are addressed. It reveals that the delay in packet transmission increases due to higher traffic loads and the number of end-devices. This result demonstrates that the existing MAC protocol works well for a small network (i.e., a network with a maximum number of 50 nodes) but is not suitable for a large network (i.e., a network with more than 50 nodes). The outcome of this research helps to design a smart car system.

An Improved Dynamic Thermal Current Rating Model for PMU-Based Wide Area Measurement Framework for Reliability Analysis Utilizing Sensor Cloud System

“…After done with equating their real and imaginary components, these four equations were performed in matrix notation as in (8). This means that the PMU measurements were breakdown into equation (9).…”

“…For real-time monitoring and data acquisition, SCS is utilized to form a wireless sensor network to incorporate all the sensors data. Wireless sensor networks have proved significant effectiveness in terms of reliability, security, and smart monitoring in the literature [8], [9]. Furthermore, SCS also provides scalability, and flexibility during real-time monitoring [10].…”

“…To interface basic gadgets of WSNs [60][61][62][63][64][65] with the internet of things [66][67][68][69][70][71] three models can be characterized: 1) the IP overlay over WSN [72], 2) the sensor overlay over IP [73], and 3) the more elevated amount entryway overlays [74]. At the point when IP overlay over WSN, sensor hubs ought to be tended to with IPs as similar hubs associated with Web.…”

A Reliable Communication and Load Balancing Scheme for Resource-Limited Networks

“…However, in later case, the communication is rather complex as each device C i has to use valuable information such as load balancing mechanism or neighboring device's information to establish a reliable transmission link with the receiver module [8]. Additionally, lifetime is still a challenging and open research problem as many to one (m:1) communication infrastructure is adopted in the resource-limited networks where sensor nodes or devices C i reside in the vicinity of the base station consume their power more rapidly than other nodes and result in energy hole [9], [10].…”
