Wireless Sensor Networks (WSNs) is the most developing areas in many factors like environment & wildlife monitoring, security & military surveillance, healthcare and many more. Also, routing protocols play a very important part in terms of efficiency in WSNs. Due to limitations of unreliable low power links and resources between the sensor nodes; design of an efficient routing protocol is...
This paper presents the prophecy of parking area in parking management system using Geographic Information System (GIS). Parking area is generated by using Google SketchUp Pro 2015. One of the most outstanding and major problems in the parking management system is to search for an empty parking space. In recent years, there has been an expanding enthusiasm from drivers to have access to real-time...
In this article, we consider software-defined wireless sensor networks (SDWSNs) and propose a scheme for sleep scheduling with low control overhead-based flow-entry in flow-table to overcome the limitation of control traffic in SDWSNs.
Solar energy harvesting is limited in industrial wireless sensor networks (IWSNs) due to dynamic nature of ambient source and network deployment strategies. In this article, we propose a sleep scheduling scheme with solar harvesting and non-harvesting nodes to combine the advantages of energy harvesting and sleep scheduling to prolong the network lifetime.
Energy consumption, transmission delay and throughput are key factors of routing in wireless sensor networks, which are relevant to channel assignment at MAC layer. This paper proposes a joint routing protocol considering requirements of MAC layer and routing layer. At MAC layer, we evaluate the channel quality via local channel load, based on which we present a Prime Frequency Hopping algorithm (PFH)...
Nowadays social networking services (SNS) have become an important part of our daily-life. Thanks to the rapid development of mobile computing technologies, more and more people start to use mobile devices, e.g., smartphones and tablets, to access the SNS. Different from the traditional way, i.e., using the desktop PCs to access the web interface of the SNS, using mobile devices will introduce more...
This paper presents a framework for the undergraduate research experience that Electrical and Computer Engineering (ECE) Senior Undergraduate students at Khalifa University, UAE pursue through a fourth-year technical elective course entitled Independent Study that is one-semester long. This course is an excellent example of self-directed learning as one of the most influential educational experiences...
In a Wireless Sensor Network (WSN) Nodes are distributed to monitor an area of interest such as a military battlefield, and transmit their data to in-situ Base-Station (BS) through multi-hop paths. In addition to collecting and processing the sensor data, the BS performs network management tasks. Due to such an important role, an adversary would try to locate the BS and target it with Denial-of-Service...
The sensor nodes in a Wireless Sensor Networks (WSNs) are responsible to collect and share the sensed information, usually by making it available at a gateway point. In this context, network connectivity plays an important role as the nodes require the availability of a path to route the sensed data to the sink node. The main contribution of this work is to propose a cooperative communication strategy...
In Agriculture, farming is an important process to provide us foods. The production of farming is increasing due to the world population increased. Scientists and Engineers are working on it in order to increase the productions and reduce the time required. Hence, planting and harvest technologies are improved significantly. However, the farming delivering process also is a very important process...
The Internet of Things (IoT) is the network of objects such as vehicles, mobile devices, and buildings with electronic components, software, and network connectivity, which enable these objects to collect data, to run commands, and to be controlled through the Internet. Controlling physical items from the Internet will increase efficiency and save time. The growing number of devices used by people...
Ultra Wideband Real-Time Location System (UWB RTLS) is a real-time positioning system with high precision, which contains a number of positioning tags and anchors, and the collision between multi tags is the main reason that affects the communication efficiency and positioning accuracy in UWB RTLS. The ALOHA algorithm and the binary tree algorithm are the mainstream of the anti-collision algorithm...

This clustering and routing method is based on maximum bottleneck energy routing (MBER) from a node to the sink. This method favors the routes with the highest...
Tracking movement of mobile nodes has received significant scientific and commercial interest, but long term tracking of resource-constrained mobile nodes remains challenging due to the high energy consumption of satellite receivers. Cooperative position tracking has been proposed for energy efficiency, however, all the cooperative schemes use opportunistic cooperation and optimize for either energy...

Multiplexing data transmission in time and frequency is an alternative to medium contention in wireless networks. The IEEE 802.15.4e standard, and its Time Slotted Channel Hopping (TSCH) mode in particular, provides such possibility in the context of constrained devices, for instance wireless sensor networks. We analyze the performance of TSCH leveraging from a real implementation in emulated environment,...
In this paper we study a wireless passive sensor network. The sensors are deployed to estimate the true values of multiple active target signals.
