Wireless Sensor Networks (WSNs) are networks consisting of many small sensor nodes capable of wireless communication, and they are used for environmental monitoring, border guards, and so on. Among many types of WSNs, data gathering WSN periodically collects to a sink node environmental information such as temperature and amount of sunlight at each point in a wide agricultural area or forest. S...

Recently, the growing concepts that information communication technologies apply to social infrastructures have caused deep interests with wireless sensor networks (WSNs). WSNs can be used for various application areas such as home, health, factory and so on. For the different application areas, there are different technical issues (e.g., security, reliability, real time gathering, long life ti...

An autonomous robot system is a distributed comprising mobile robots that perform tasks of interest such as formation and flocking. In basic model when have no lights (no memory communication devices), Gathering, type problem asks all the to meet at single point not known priori, impossible if semi-synchronous (SSYNC, subset synchronously activated each time) or even centralized (only one [7], ...

Smartphone sensors are being increasingly used in mobile applications. The performance of sensors varies considerably among different smartphone models and the development of a cross-platform mobile application might be a very complex and demanding task. A publicly accessible resource containing real-life-situation smartphone sensor parameters could be of great help for cross-platform developer...

Wireless sensor and actuator networks provide a distributed system composed of wirelessly connected smart sensor and actuator nodes, suitable for cost-efficient control applications. An important research challenge is deployment, where features like node auto-configuration, unattended operation, and Internet connectivity are becoming mandatory. Moreover, on off-the-shelf solutions the user typi...

The location information is very important in many wireless sensor network applications where in from which node the data is generated needs to be determined. Therefore it becomes necessary to know the location of each and every sensor that is deployed in the network. In our proposed Localization technique we have deployed static sensors in the geographical area of the network which are used fo...
