Abstract
Due to the increased demand of wireless sensor networks for their characteristics like low energy consumption, robustness, and low cost in several demanding and complex applications like smart grid, health and safety, traffic and weather updates, there is need of monitoring the infrastructure in a timely manner with high reliability. In this article, a cross-layer data communication scheme target-aware cross-layer technique is proposed to enhance reliability and to reduce the latency in wireless sensor networks. The proposed scheme uses connected dominating set at network layer where nodes in the connected dominating set are directly connected to all the other nodes in the network. Each sensor node sends the data to the nodes present in the connected dominating set, which forwards it to their respective destinations. The proposed scheme reduces the chances of collision resulting reduced delays. Higher packet delivery ratio is achieved with the proposed scheme results in improved reliability. The proposed scheme is outperforming other state-of-the-art schemes in terms of packet delivery ratio, latency, and data throughput with the default 802.15.4 and delay-responsive cross layer in both static and mobile scenarios using network simulator tool.
Highlights
Wireless sensor networks (WSNs) are becoming a prevailing technology nowadays
A target-aware cross-layer technique (TACT) for data communication was proposed in this article with a goal to achieve low latency, lower end-toend packet delay, lower energy consumption, and good throughput with enhanced reliability in WSNs
To check the effectiveness of the proposed technique, TACT was applied to both mobile scenario like Internet of Things (IoTs) and static scenarios like smart grid with variable number of sensor nodes
Summary
Wireless sensor networks (WSNs) are becoming a prevailing technology nowadays. This is due to their wonderful features like robustness and their vast applications in real-life scenarios. The applications are control processes, monitoring smart grids, and various applications of Internet of Things (IoTs) To achieve this target, WSNs must have to promise to provide a certain set of characteristics, which includes a robust Quality of Service (QoS) support. The effect of equipment failure, capacity limitations, and natural accidents generally lead to power failure This can be avoided to a large extent by online power monitoring, control, diagnostics resulting in power system protection. In a critical application like smart grid, utilities and customers are considered as intelligent nodes of a communication network that are able to distribute real-time information. For this reason, the existence of an efficient communication system becomes the main factor in the successful working of the smart grid. The article is concluded in ‘‘Conclusions and future directions’’ section
