Mobile wireless sensor networks (MWSNs), the continuous movement of sensor nodes, may cause complete disconnection of the network or at best a part of it. The design of such networks should guarantee that all sensor nodes at all times have a path to the sink node(s). Prolonging the lifetimes of the MWSNs is a crucial design issue but should not be at the expense…
Abstract: The rapid development of medical sensors has increased the interest in Wireless Body Area Network (WBAN) applications where physiological data from the human body and its environment is gathered, monitored, and analyzed to take the proper measures. In WBANs, it is essential to design MAC protocols that ensure adequate Quality of Service (QoS) such as…
Building a Wireless Sensor Network Using Smartphones Introduction One of the Tech. Briefs last month (November 2011) – The Sensor Cloud and Homeland Security – briefly outlined how Homeland Security agencies can use cloud computing to store and process surveillance sensor data. Although the focus in that brief was on traditional surveillance sensors – video…
Smart, wireless networked sensors will soon be all around us, collectively processing vast amounts of previously unrecorded data to help run factories, optimize farming, monitor the weather and even watch for earthquakes. Many people (including me) think that wireless sensor networks can become as important as the Internet. Just as the Internet allows access…

You are visitor Overview Wireless sensor and actor networks (WSANs) refer to a group of sensors and actors linked by wireless medium to perform distributed sensing and actuation tasks. The physical architecture of the WSAN is given in Figure 1. In such a network, sensors gather information about the physical world, while actors take decisions and then perform…
Recent advances in Wireless Sensor Networks (WSNs) have led to several emerging applications in pervasive medical care. A combination of Wireless Body Area Networks (WBANs) with wearable or implantable sensors and contextual information could potentially advance medical monitoring, diagnosis, treatment and patient care. There are numerous challenges to realization…
The I Transactions on Control of Network Systems publishes high-quality papers on systems with interconnected components. The journal is primarily interested in problems related to the control of network systems but is also open to contributions concerning their design, study, engineering, optimization, and emerging behavior as these can inform and guide design…
Sensor networks are inherently communication-centric systems. The sensor nodes form wireless networks through which sensor readings can be transported or where nodes can act directly on data communicated from their neighbours. For sensor nodes to build networks, they need network protocols. The network protocols define the sequence of steps for the nodes to take…
The development in the communication systems and the networking has given rise to the wireless networks. The ease and flexibility of wireless communication has enabled us to use personal assistance devices to be used anywhere. This has enabled the mankind to excel in every field of the life, but at the same time it has many threats as well. Security threats to…
Wireless sensors networks (WSNs) are traditionally composed of large number of low-cost and tiny homogenous sensors nodes connected through a wireless network that gather data to be treated locally or relayed to the sink node through multi-hop wireless transmission. Moreover, such issues are very critical due servers resources constraints like efficient energy…
More than the 70% of the earth surface is covered with water (almost all of that is the ocean). New technologies have brought us new ways to monitor and sense aquatic environments. Marine surveillance, pollution detection and monitoring, and oceanographic data collection are needed to explore, protect, and commercial exploit the aquatic environment. Many potential…
The US Department of Defense (DoD) routinely uses wireless sensor networks (WSNs) for military tactical communications. Sensor node die-out has a significant impact on the topology of a tactical WSN. This is problematic for military applications where situational data is critical to tactical decision making. To increase the amount of time all sensor nodes remain…
With the increasing deployment of the Internet of Things (IoT) applications, the demand for energy efficiency (EE) and quality-of-service (QoS) guarantee is on the rise. This paper considers the typically contradicting requirements for EE and QoS provisioning in an integrated manner for an I 802.15.4-based wireless sensor network (WSN). Specifically, we consider…
Nearly 1.3 billion people, mostly living in less developed countries, do not have access to electricity.
