A rule-based framework for heterogeneous subsystems management in smart home environment

Recent advancements in computing and communication technologies have increased the growth of heterogeneous subsystems in smart home environment. However, many of these heterogeneous systems are standalone and do not adapt towards joint execution of tasks. Hence, it is rather difficult to perform interoperation especially to realize desired services preferred by home dwellers. In this paper, we propose a new rule-based framework for heterogeneous systems management as well as coordinating them by means of federated manner in smart home environment. The proposed framework is based on event-condition-action (ECA) rule mechanism with SOAP technology that provides interoperability among those systems. We have implemented the framework with several subsystems to demonstrate their effectiveness for interoperation using ECA rule mechanism. The performance of the framework was tested in LAN environment and proves to be reliable in smart home setting.

Interoperability among Heterogeneous Systems in Smart Home Environment

The smart home environment is highly characterized by heterogeneity with many systems that need to interoperate and perform their tasks efficiently. With rapid growth of services, applications and devices in smart home environment, the interoperability factor seems still elusive. This is due to the nature of smart home as distributed architecture that needs certain degree of interoperability and interoperation for managing heterogeneous systems comprising of different platforms. These heterogeneous systems are developed in isolation and consist of different operating systems, different programming platform and different tier of services. There is need for a mechanism that could make the heterogeneous systems `talk¿ each other and interoperate in an efficient manner regardless of operating platform. Web services seems to be state-of-the art technology that could be one potential solution in providing greater interoperability. In this paper we describe interoperability issues that need to be considered and we present a solution based on Simple Object Access Protocol (SOAP) technology to solve the interoperability problem in smart home environment.

Design and implementation of SOAP-based residential management for smart home systems

This paper presents the design and implementation of SOAP-based residential management for smart home systems appliances control. An appliance control module based on SOAP and Web Services developed to solve the interoperation of various home appliances in smart home systems. 15 feedback based control channels implemented with residential management system through Web Services. If the residential management system experiences server downtime, the home appliances can still be controlled using alternate control mechanism with GSM network via SMS Module locally and remotely. This system offers a complete, bi-directional real-time control and monitoring of smart home systems.

Interoperability framework for smart home systems

Recent advancements in smart home systems have increased the utilization of consumer devices and appliances in home environment. However, many of these devices and appliances exhibit certain degree of heterogeneity and do not adapt towards joint execution of operation. Hence, it is rather difficult to perform interoperation especially to realize desired services preferred by home users. In this paper, we propose a new intelligent interoperability framework for smart home systems execution as well as coordinating them in a federated manner. The framework core is based on Simple Object Access Protocol (SOAP) technology that provides platform independent interoperation among heterogeneous systems. We have implemented the interoperability framework with several home devices to demonstrate their effectiveness for interoperation. The performance of the framework was tested in Local Area Network (LAN) environment and proves to be reliable in smart home setting1.

Internet of Things (IoT) enabled water monitoring system

Water is always a crucial part of everyday life. Due to global environmental situation, water management and conservation is vital for human survival. In recent times, there were huge needs of consumer based humanitarian projects that could be rapidly developed using Internet of Things (IoT) technology. In this paper, we propose an IoT based water monitoring system that measures water level in real-time. Our prototype is based on idea that the level of the water can be very important parameter when it comes to the flood occurrences especially in disaster prone areas. A water level sensor is used to detect the desired parameter, and if the water level reaches the parameter, the signal will be feed in realtime to social network like Twitter. A cloud server was configured as data repository. The measurement of the water levels are displayed in remote dashboard.

Rule-based conflict resolution framework for Internet of Things device management in smart home environment

Recent developments in Internet of Things (IoT) tremendously have introduced several heterogeneous systems and devices that characterize a smart home. Generally, these heterogeneous systems are dissimilar and accomplish various services and functionalities. Due to the gradual changes of managing resources in smart home, more heterogeneous systems are being introduced from time to time depending on the consumer requirement. As such, more dependencies are created among heterogeneous systems, and this could lead towards conflict occurrences among them. Conflicts could occur in smart home when two or more events generated by heterogeneous systems need to be triggered at an instance of time. In this paper, we present a rule-based conflict resolution framework using scheduling algorithm for managing heterogeneous systems in smart home environment. Events are captured and processed by the framework which performs corresponding conflict resolution on the heterogeneous systems. The developed framework was implemented with several heterogeneous systems to validate their effectiveness in solving conflict occurrences. The framework was ascertained to be consistent in smart home environment.
