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…
