Modern cities are blanketed with Wi-Fi Hotspots. Such network access points can be utilised by Internet of Thing devices to enable wireless sensor network data mining deployments to report to the cloud. Vehicles are such devices that can provide valuable data sensing platforms for both internal operational properties such as speed, fuel and engine heat as well as external environmental features including...
Recently, a tremendous interest has been concentrated on the design and development of wireless sensor networks (WSNs) — distributed systems comprised of numerous wireless, sensor devices deployed densely in a sensing area. Battery powered sensors need efficient management due to limited energy resources, and energy conservation is a vital design issue that needs to be boosted in order to increase...
Recently, the SDN paradigm, which splits the control and data planes, initially defined for wired networks, has been considered as a solution for the management of WSNs (Wireless Sensor Networks). However, the adoption of OpenFlow protocol, the most widely deployed SDN standard, directly into the WSNs may require novel / customized hardware or incur significant signaling overhead. This paper proposes...
As Sensor Node (SN) has unique functionalities and properties which help to distinguish from traditional communication networks. From various latest scenarios, WSN characteristic are based on ontologies plays a vital role to sense, manage, integrated, analyzed, and exploited further for interactive and intelligent processing. Mainly in the paper, our target is to mitigate the Energy Efficiency, Data...
The resource-constrained nature of sensor nodes makes wireless sensor networks (WSNs) especially susceptible to denial-of-service (DoS) attacks. Due to the wireless communication medium, it is difficult to prevent attacks such as jamming. Hence, mechanisms to detect attacks during operation are required. The current generation of intrusion detection systems are still rather heavyweight, as some form...
It has been found that almost all routing protocols can induce network congestion due to control message complexity. To overcome this overhead various optimization processes are used. One such process is gossiping, where each node forwards a message with some probability, to reduce the overhead of the routing protocols. In this paper, we show how gossiping can be used to improve the performance of...
Collecting data in time is crucial for the wireless sensor network (WSN), especially for some WSNs who suffer from inconstant link connections. Our observations in the intertidal wireless sensor network (IT-WSN) reveal that end-to-end delay is severe and a big challenge to be solved. Existing routing protocols perform well in WSNs with good link quality but show deficiency when node states change...
Aimed at the inapplicability of LEACH protocol for large-scale sensor network and uneven energy consumption, a Distributed Self-organizing Clustering Routing protocol (DSCR) for large-scale sensor network is proposed. Based on clustering, the network routing is divided into two levels: parent cluster and cluster. The cluster structure is formed by the back-off mechanism related to the residual energy...
Recent advances in technology propelled the development of resource constrained tiny devices and the concept of Internet of Things (IoT). Potential applications spanning various fields of science from environmental to medical have been emerged. Different architectures, routing protocols, performance issues and goals have been suggested. In this work, we review fundamental concepts, recent developments...
Time Slotted Channel Hopping (TSCH) networks are emerging as a promising technology for the Internet of Things and the Industry 4.0 where ease of deployment, reliability, short latency, flexibility and adaptivity are required. Our goal is to improve reliability of data gathering in such wireless sensor networks. We present three redundancy patterns to build a reliable path from a source to a destination...
The occurrence of multiple holes in wireless sensor networks poses many challenges in designing routing protocols. The traditional scheme is forwarding packets along the hole perimeters. However, this scheme leads to two serious problems: data concentration around the hole boundaries and routing path enlargement Recently, several approaches have been proposed to address these two problems, wherein...
These days wireless sensor networks are being used in many different fields. Limited energy and efficient usage of energy are the most important factors that should be considered in these networks. Node clustering increases the efficacy of the energy consumption. Each cluster has a cluster head(CH) that is a member of that cluster and its duty is sending and receiving data in the network. So finding...
Wireless Mesh Network (WMN) is an upcoming technology that supplements wired infrastructure with wireless backbone to provide Internet connectivity to mobile nodes (MN) or users in residential areas and offices. Here the each wireless backbone node operates both as a wireless router that forwards packets of other nodes & as a wireless bridge transmitting the packets of its clients WMN has the...
Wireless sensor networks (WSNs) are used in many mission-critical applications, such as target tracking on a battlefield, emergency alarms, and disaster detection. In such applications, QoS provisioning in the timeliness domain is indispensable. Moreover, because of the diversity of sensory data, QoS provisioning should support not only one but multiple levels of end-to-end delay constraints. As a...
This work discusses the concurrent applications of data collection and reconfiguration, and proposes a novel reconfiguration scheme during data collection. The proposed scheme incorporates the advantages of both proactive and reactive protocols into one system: using proactive protocol to collect continuous data and reactive protocol to reconfigure each remote node of the network. In addition, three...
RPL (the IETF Routing Protocol for Low-Power and Lossy Networks) and LRP (Lightweight Routing Protocol) have in common to build a collection tree (or, more precisely, a DODAG) and "downward" host routes in the wireless sensor network. Additionally, the objective of LRP is to keep control overhead as low as possible. To substantiate this claim, we compare RPL and LRP using 40 nodes of the...
