Special Issue Information

Dear Colleagues,

Wireless sensor and actuator networks (WSANs) are becoming the emerging networking infrastructure for cyber-physical systems as WSANs offer numerous advantages beyond traditional communication networks. A wireless sensor and actuator network is the integration of embedded computing devices, sensors, actuators, and wireless communication mechanisms. WSANs operate in a closed “sense-think-act” loop of environmental data gathered by sensors, then processed by embedded computing devices to issue decisions, and wirelessly transferred actuators to make changes to the environments. The closed loop enables WSANs to sense and perceive, interact, and manipulate the physical world directly without human operation, providing great potential for our daily-life applications.

The aim of this Special Issue is to gather the most recent research results of wireless sensor and actuator networks. We invite all papers with theoretical and experimental contributions within, but not limited to, the following topics:

  • Current state of the art of WSANs
  • System design and integration in WSANs
  • Embedded hardware and software for WSANs
  • Sensory data gathering and processing in WSANs
  • Signal processing in WSANs
  • Throughput optimization of WSANs
  • Delay and jitter of WSANs
  • Routing protocols of WSANs
  • Energy maximization of WSANs
  • Mobility in WSANs
  • Deployment and exploration of WSANs
  • Reliability of WSANs
  • Information security in WSANs
  • Applications in WSANs
  • Constrained optimization of WSANs
  • Soft-computing techniques applied for WSANs
  • Control engineering applied for WSANs

The use of wireless communications for real-time control applications poses several problems related to the comparatively low reliability of the communication channels. This paper is concerned with adaptive and predictive application-level strategies for ameliorating the effects of packet losses and burst errors in industrial sampled-data Distributed Control Systems (DCSs), which are implemented via one or more wireless and/or wired links, possibly spanning multiple hops. The paper describes an adaptive compensator that reconstructs the best estimates (in a least squares sense) of a sequence of one or more missing sensor node data packets in the controller node. At each sample time, the controller node calculates the current control, and a prediction of future controls to apply over a short time horizon; these controls are forwarded to the actuator node every sample time step. A simple design method for a digital Proportional Integral Derivative (PID)-like adaptive controller is also described for use in the controller node. Together these mechanisms give robustness to packet losses around the control loop; in addition, the majority of the computational overhead resides in the controller node. An implementation of the proposed techniques is applied to a case study using a Hardware in the Loop (HIL) test facility, and favorable results (in terms of both performance and computational overheads) are found when compared to an existing robust control method for a DCS experiencing artificially induced burst errors.

Using multiple channels in wireless sensor networks helps increase the overall throughput and avoid interferences. In addition, introducing multi-interface nodes further helps in increasing the packet delivery rate for those specific nodes. In this paper, we evaluate a channel allocation method based on neighborhood discovery up to 3 hops and a hybrid MAC protocol designed for high data rate wireless sensor networks. We propose a network segmentation that takes into consideration the existence of multi-interface sink in order to further increase to packet delivery ratio. Our protocol, called HMC-MAC, uses Time Devision Multiple Access (TDMA) for sequencing nodes activity, and Carrier Sense Multiple Access (CSMA)/CA with Frequency Devision Multiple Access (FDMA) for simultaneous data exchange. We evaluated our method using NS2 simulator and results show that HMC-MAC protocol improves the overall network performance compared to other protocols especially with high data rate and burst traffic.
