In the modern days, computing technology has been demanding which is called an Internet of Things (IoT). This IoT technology can be united with a variety of electronic and mechanical devices through cloud computingnetworking. IoT is a smart device which provides a solution for connecting, interacting and communicating to machine-to-machine using sensor network and Radio Frequency Identification (RFID) technologies, etc. Using IoT, the device can be connected easily and the generated data can be stored. Using the command and control system, the data can be utilized for appropriate applications which makes human life easier and safer. Also, it provides a huge impact on the industry. In this paper, a novel IoT based interface device for automatic molding machine (AMM) towards SMART FOUNDRY 2020 is proposed where this IoT based interface device solves the problem of the man-machine interface in the industry. A Graphical User Interface (GUI) based software is designed which interfaced the different sensors, actuators, and electronics motors, etc. SMART FOUNDRY-2020 is regulated using a GUI for its manual and automatic control. GUI is designed to interact with the automatic molding machine with the users. Subsequently, this data is connected to the cloud platform to store data and analyze the application functionality of automatic molding machine. This shows the potential of IoT in SMART FOUNDRY.

In the mobile wireless sensor network, topology control is a challenging topic. In this paper, a mobile topology control framework is proposed. The network is sampled periodically, the stationary topology control algorithm is implemented repeatedly, and a common redundant transmission range Is applied to each node guarantee a certain probability of connectivity. With extensive simulations, this paper Investigates the settings of sampling time and redundant transmission range, for the given network deployment, mobility model, and topology control algorithm. The balance between three performance criteria in the mobile topology control algorithm is considered, including probability of connectivity, communication load, and energy ef ciency.

MODBUS is still one of the most widespread application layer protocols used in industrial communication due to its simple request-response communication session and its readiness to be implemented on top of several lower level communication protocols and various physical media such as RS232/RS485 serial lines and Ethernet TCP/IP. Given the well-known inclination of Modbus to inter-networking, a solution to connect a wireless sensor and actuator network (WSAN) based on the PHY layer as defined by IEEE 802.15.4 and one of the MAC behaviour modes proposed by the IEEE 802.15.4 amendment to SCADA applications is investigated in this paper. A simple low latency deterministic network (SLLDN) and a MODBUS/SLLDN gateway were implemented to have a WSAN interfaced to a NI Lookout SCADA server application for data acquisition and control using its built-in MODBUS serial driver.

Power control in wireless networks is important to maintain reliable communication links between base stations and nodes, and to maximize the battery life. An energy aware connectivity set based transmission power control protocol is presented in this paper. We augment our distributed protocol with a heuristic that considers energy cost information when making power control decisions. Compared to traditional protocol, our protocol can improve energy efficiency and prolong network lifetime significantly, while networks connectivity is still maintained in extreme scenarios. Simulation results demonstrate our conclusion.

Cyber-physical systems (CPSs) are emerging as a new technology, which is used to provide seamless interaction between the physical and cyber worlds. This novel paradigm is a natural evolution and extension of wireless sensor networks (WSNs) and control models to allow for effective monitoring and control of physical systems from the computing environment. In order to support this interface and allow such smooth interactions, efficient networking and communication between the physical and cyber worlds take a very important and critical role. In this paper, we identify the various categories and applications of CPS systems, and characterize the associated data traffic that is generated. We also discuss the different protocols and requirements that are needed at the various networking layers for these applications. Subsequently, we identify important parameters such as bandwidth, delay, reliability, security, and mobility, which are essential in order to allow for effective and robust operation of the various CPSs.

Wireless sensor networks are mainly designed for environment monitoring. The life time of wireless sensor networks depends on the durability of the battery resource sensors, so it is crucial for sensors to efficiently use their limited battery resources. The energy expends by sensors in data communication makes up a significant quantum of their total amount of energy consumption. In the existing research, most of the power-saving medium access control protocols reduce energy consumption by putting periodically sensors to sleep mode. Such a regular active/sleep schedule fails to adjust individual sensor sleep duration according to per-sensor communication traffic-load, which causes unnecessary idle-listening problem and low power-efficiency. In this paper, we present a new power-saving medium access control protocol for saving power in a wireless sensor networks. This proposed protocol dynamically adjusts the active/sleep time duration of each sensor according to per-sensor communication traffic-load. Meanwhile, it can lead to much greater power-efficiency by prolonging the sensors sleeping duration, when in a sensor network at per-sensor communication traffic-load is low. The basic idea of this proposed protocol is an analytical model for estimating the accurate per-sensor communication traffic-load in a wireless sensor network and a grid-based quorum concept for regular active/sleep schedule.

Wireless sensor network (WSN) has the characteristics of large-scale, low cost, low power consumption and high network invulnerability, which can meet the needs of large-scale and fast networking of intelligent distribution communication system. Because the sensor nodes in WSN of intelligent distribution network have great differences in computing power, storage space, energy and so on, in order to achieve efficient and reliable communication links, it is more appropriate to use heterogeneous nodes for WSN networking of intelligent distribution network. In this paper, the node design method, node deployment method and network routing protocol of intelligent distribution network WSN based on heterogeneous nodes are systematically studied. The transmission success rate basically meets the demand of more than 80%.
