A distributed multi-agent approach for resilient supervision over a IPv6 WSAN infrastructure

Abstract

Wireless Sensor and Actuator Networks has become an important area of research. They can provide flexibility, low operational and maintenance costs and they are inherently scalable. In the realm of Internet of Things the majority of devices is able to communicate with one another, and in some cases they can be deployed with an IP address. This feature is undoubtedly very beneficial in wireless sensor and actuator networks applications, such as monitoring and control systems. However, this kind of communication infrastructure is rather challenging as it can compromise the overall system performance due to several factors, namely outliers, intermittent communication breakdown or security issues. In order to improve the overall resilience of the system, this work proposes a distributed hierarchical multi-agent architecture implemented over a IPv6 communication infrastructure. The Contiki Operating System and RPL routing protocol were used together to provide a IPv6 based communication between nodes and an external network. Experimental results collected from a laboratory IPv6 based WSAN test-bed, show the relevance and benefits of the proposed methodology to cope with communication loss between nodes and the server.

A Distributed Multi-Agent Framework for Resilience Enhancement in Cyber-Physical Systems

“…The sink node is attached via a USB port to this single board computer, where the Tunslip is running and the router implemented. All of these devices allow IPv6 communication directly between the WSAN nodes and the remaining system, creating a Serial Line Protocol (SLIP) tunnel between the physical serial port and the virtual network interface [46]. Three remote network devices located on PC 1 , PC 2 and PC 3 allow the external interaction with the physical system over the WSAN.…”

Design and Implementation of a Wireless Sensor and Actuator Network to Support the Intelligent Control of Efficient Energy Usage

“…Some recent research has been carried out addressing all levels of WSAN technology: from the enhancement of the internal network organization, such as shown in [ 10 ] where different solutions for managing nodes and their interactions are analyzed and classified, or that in [ 11 ] where a system based on Deep Q-Network is proposed for mobile actor node control in WSANs; to the optimization of the nodes placement as proposed in [ 12 ], or the allocation of tasks to actuators found in [ 13 ]. All these ideas can be complemented with improvements in communications between nodes such as those presented in [ 14 ], where the use of a network over an IPv6 infrastructure is proposed. Also with the use of new algorithms to enhance the traffic forwarding capacity of nodes as described in [ 15 ], with proposals for reducing congestion and improving the network performance as in [ 16 ], a novel channel hopping methods for the exchange of data packages presented in [ 17 ], or an approach for enhancing the lossy link localization in [ 18 ].…”
