“…To evaluate the performance of CROMC, we further compare the results of CROMC with the two other latest methods on multichannel sensor networks. The first one is EFP, 12 which is based on a hop-by-hop transport scheme and seeks the minimum power consumption, the other one is HMCA, 14 which is based on hybrid TDMA techniques and seeks the maximum throughput under the premise of delay control. Similar to the above analysis, η = 6500 is used.…”

“…Several OSAs based on MAC (medium access control) schemes in CR networks are discussed in detail in Sultana et al 11 The differences between the conventional MAC protocols and OSA-based MAC protocols were investigated. Palma 12 proposed a new communication protocol, named as energy efficiency protocol (EFP), is based on a hop-by-hop transport scheme and is especially devised to simultaneously solve the network energy consumption and the performance of the closed-loop system. The proposed protocol can be implemented by means of three heuristics, basically using distinct rules to control the maximum number of retransmissions allowed in terms of the voltage level of the batteries of the network nodes.…”

With the development of modern communication, available spectrum resources are becoming increasingly scarce, which reduce network throughput. Moreover, the mobility of nodes results in the changes of network topological structure. Hence, a considerable amount of control information is consumed, which causes a corresponding increase in network power consumption and exerts a substantial impact on network lifetime. To solve the real-time transmission problem in large-scale wireless mobile sensor networks, opportunistic spectrum access is applied to adjust the transmission power of sensor nodes and the transmission velocity of data. A cognitive routing and optimization protocol based on multiple channels with a cross-layer design is proposed to study joint optimal cognitive routing with maximizing network throughput and network lifetime. Experimental results show that the cognitive routing and optimization protocol based on multiple channels achieves low computational complexity, which maximizes network throughput and network lifetime. This protocol can be also effectively applied to large-scale wireless mobile sensor networks.

“…The most recent research in the WSN literature is concerned with improving the robustness of the network by using, for instance, topology optimization models to help WSN resist cascading failures [ 2 , 3 ], information fusion processes to lower the negative impact of the environment on message routing [ 4 ], and more realistic failure models to analyse the network invulnerability [ 5 ]; etc. However, if the network is used as a communication channel for NCS projects, there are some alternative techniques that guarantee the robustness of the closed-loop system even under, for instance, denial of service in cyber-physical attacks [ 6 , 7 ], network-induced delays [ 8 ], and packet loss, among several other issues [ 9 , 10 , 11 ]. In this sense, despite their advantages, the most common and least wanted feature of the NCS is the possibility of packet loss in the network.…”

This paper deals with the problem of control through a semi-reliable communication channel, such as wireless sensor networks (WSN). Particularly, the case investigated is the one where the packet loss rate of the network is time-varying due to, for instance, variation in the distance between the nodes. Considering this practical motivation, the control system is modeled using a formulation based on discrete-time Markov jump linear systems (MJLS) with non-homogeneous Markov chains (time-varying transition probabilities). New control design conditions based on parameter-dependent linear matrix inequalities are proposed in order to solve this problem. The purpose is to demonstrate that this strategy is suitable to handle the networked control problem by comparing the temporal behavior of the closed-loop system with the Markovian controller and a standard proportional-integral-derivative (PID) controller. The case study presented in the paper considers the problem of the remote control of a Vertical Take-Off and Landing (VTOL) vehicle through a wireless communication channel. The network packet loss model employed in the case study is based on data collected on a wireless network workbench, which was previously developed and validated by the authors.

Currently, wireless sensor network (WSN) protocols are mainly used to achieve low power consumption of the network, but there are few studies on the quality of services (QoS) of these networks. Coverage can be used as a measure of the WSN’s QoS, which can further reflect the quality of data information. Additionally, the coverage requirements of regional monitoring target points are different in real applications. On this basis, this paper proposes an energy-efficient clustering routing protocol based on a high-QoS node deployment with an inter-cluster routing mechanism (EECRP-HQSND-ICRM) in WSNs. First, this paper proposes formula definitions for information integrity, validity, and redundancy from the coverage rate and introduces a node deployment strategy based on twofold coverage. Then, in order to satisfy the uniformity of the distribution of cluster heads (CHs), the monitoring area is divided into four small areas centered on the base station (BS), and the CHs are selected in the respective cells. Finally, combined with the practical application of the WSN, this paper optimizes the Dijkstra algorithm, including: (1) nonessential paths neglecting considerations, and (2) a simultaneous introduction of end-to-end weights and path weights, achieving the selection of optimal information transmission paths between the CHs. The simulation results show that, compared with the general node deployment strategies, the deployment strategy of the proposed protocol has higher information integrity and validity, as well as lower redundancy. Meanwhile, compared with some classic protocols, this protocol can greatly reduce and balance network energy consumption and extend the network lifetime.
