With advancement in the concept of internet of things (IoT), many industrial applications today have migrated from wired to wireless communication protocols. The major requirements of industrial devices utilizing wireless technologies include high performance reliability similar to wired network, and longevity in terms of battery life. Wireless fie...

In an industrial plant, there is usually a mix of devices with different levels of security features and computation capabilities. If a mix of devices with various degrees of security features and capabilities communicate, the overall network dynamics with respect to security and network performance will be complex. A secure communication path with...

Remote health monitoring is one of the emerging IoT applications that has attracted the attention of communication and health sectors in recent years. We enable software defined networking in a wireless sensor network to provide easy reconfiguration and at run-time network management. In this way, we devise a multi-objective decision making approac...

Congestion control is a challenging issue in wireless sensor networks with limited channel bandwidth. Thus, many protocols have been designed to provide a distributed traffic control during packet forwarding. However, all these approaches are applied to single-hop communication networks, ignoring the multi-hop restrictions. In this work, we take ad...

The next-generation electrical power system is focusing on reliable, automated, and secure power grid by using information and communication technology (ICT). To realize the new generation of power grid, the communication network is a decisive piece of the entire smart grid. Communication infrastructure in smart grids is a combination of both wired...

A key aspect of realizing the future smart grid communication solution is a balanced approach between the network performance and the network security during the network deployment. A high security communication flow path is not useful when the network path cannot support capacity and reachability requirements. The deployment phase in communication...

An efficient key management system is required to support cryptography. Most key management systems use either pre-installed shared keys or install initial security parameters using out-of-band channels. These methods create an additional burden for engineers who manage the devices in industrial plants. Hence, device deployment in industrial plants...

Industrial plants are heterogeneous networks with different computation and communication capabilities along with different security properties. The optimal operation of a plant requires a balance between communication capabilities and security features. A secure communication data flow with high latency and low bandwidth does not provide the requi...

Industrial device commissioning along with the initial distribution of keying material is an important step for the security of industrial plants. An efficient key management system is required in cryptography for both symmetric key or public/private key encryption. Most of the key management system use either pre-installed shared keys or install k...

The oil and gas industry has unique workflow, working conditions, and other operational and environmental factors that demand an online inventory management solution which can effectively monitor the offshore operations, provide safe workplace for site personnel and track the movement of assets for distribution across the supply chain. Tremendous g...

Over the last decade the wireless technology has gained interest in process automation world due to its cost effectiveness, rapid deployment and flexibility features. However, the deployment of wireless technology in industrial environment demands same integration approach as compared to traditional wired device integration. This is one of the impo...

The security of industrial plants has gained a lot of importance since the last decade. The reason is that the different components from different network layers of automation systems have become inter-connected to support fast and cost-effective decisions at the management level. This inter-connectivity has posed many security challenges in this i...

In any security design, the initial secret distribution for further key management solution is a major step. In industrial wireless sensor networks also, initial bootstrapping of the trust in the system is a major concern. The plant can be assumed to be a closed system, where only authenticated and trusted users are allowed to enter. However, wirel...

This paper provides an insight of cost effective deployment of wireless sensor network in a large plant to control the environment for optimizing power consumption, while maintaining the desired comfort level for workforce and equipments. Temperature and humidity are the two primary parameters which determine the comfort level. These data need to b...
