Cluster structure is one of the most important structures that have received increasing attention over recent years. This paper presents a modification to the structure of the cluster tree Wireless Sensor Network (WSN) dividing clusters into sub-groups. Each group of these sub-groups operates like a tree from a small number of nodes. The results from the implemented adjustments indicate a significant...
With WSN technologies becoming more reliable, sophisticated and more capable of meeting the demands of market opportunities and with its broad applications and new emerging trends like: internet of things and integrated web-based services, there still a need for developing protocols to manage and improve coherence and consolidation of the network. Video sensing can be involved in most of the WSN applications...
Sustainability of old buildings is constantly challenged due to its non-compliance with energy saving practices. Old buildings which aim to deploy technologies to improve thermal comfort face some infrastructure constraints. The sustainability of such buildings is dependent on occupant's thermal comfort, low carbon emissions and reduced energy consumption. Such buildings face restraints in the way...
Assistive technologies are deployed to preserve good health and security of elderly people living independently in their own home. One such technology is the indoor localization which helps to detect the level of their daily activities. Among low intrusive technologies, the RF signal strength (RSSI) is a very attractive approach as it does not need additional localization hardware and is being already...

In this paper, a gateway system between the wireless sensor network (WSN) and TCP/IP is designed for home automation applications. The fundamental components of this system are switches connected to WSN, the gateway between WSN and TCP/IP and a user interface program which can be used to show incoming and outgoing data to the users. The switch units are the end-devices of the WSN. There are WSN and...
The ZigBee technology is a new wireless communication technology with the characters of low cost, low complexity and low consumption. Aiming at the requirement of the special environmental and security-defense of SMT workshop, an intelligent SMT workshop monitoring system based on ZigBee wireless sensor network technology is provided. This system makes the SMT workshop discrete devices as an entirety...
Compressed Sensing is a novel theory that has been playing a significant role in the area of image processing, signal processing, wireless communication and sensor networks etc. As the signals in wireless sensor networks are sparse as compared with the number of nodes, therefore compressed sensing method is adaptive for data transmission among sensor nodes. In this paper, we propose a compressed sensing...
Wireless sensor networks (WSNs) have received lots of attention in recent years. WSNs have been applied to multiple fields such as video surveillance, home automation, and health care. How to efficiently manage WSN devices thus becomes an important issue. Simple Network Management Protocol (SNMP) is an IP-based network management protocol which can collect and modify management information from network...
Traditional methods of monitoring production in enterprises by humans on site are unable to meet the expectations for efficiency, accuracy and cost as product lifecycles are shortened continuously. Setting up an RFID and ZigBee based manufacturing monitoring system is a good approach to improve monitoring efficiency so as to improve management efficiency in enterprises. Although there are still some...
This paper presents the development of MMIM (Middleware for Monitoring and Information Management): a collection of software that communicates a wireless sensor network (WSN) based on IEEE 802.15.4 standard with a web site. The WSN collects vital signs of patients and sends them to a database located in a web server. On the other end, people who care for the health of these patients, monitor the web...
Wireless Sensor Networks (WSNs) operate in hostile environments under resource-constrained conditions. Power conservation is a primary factor that drives the design of these networks. Therefore, WSNs should not utilize complex algorithms that are power-hungry. The IEEE 802.15.4 standard is the appropriate suite of specifications that conforms to the distinguished characteristics of WSNs. This standard...
