Large scale monitoring systems require reliable and efficient routing protocols used to overcome the limitations introduced by battery operated embedded devices, among which, energy consumption is considered the main concern. This topic has gained a lot of interest in the last decade. Due to numerous advantages, clustering is becoming more prevalent as a routing technology in WSN. This paper describes...
Climate change and resultant scarcity of water are becoming major challenges for countries around the world. With the advent of Wireless Sensor Networks (WSN) in the last decade and a relatively new concept of Internet of Things (IoT), embedded systems developers are now working on designing control and automation systems that are lower in cost and more sustainable than the existing telemetry systems...
For reliable control of the cardiovascular, respiratory, musculoskeletal systems of the human body must be continuously recorded electro-cardio signal for a long time. Detected and quickly transferred over the wireless channel the most informative pieces of daily electro-cardio signal will allow duty cardiologists for react and provide the necessary medical care to remote cardiac patients. The sequences...
The Wireless Sensor Networks (WSNs) are widely being used for monitoring different environments and are very effective for monitoring those areas where human presence can be critical. Meanwhile, Cloud Computing (CC) has emerged as a very large scale computational and storage service with pay-as-you-go usage model which has taken the WSN to entirely a new paradigm. This integration of WSN with CC provides...
A reliable and efficient security system on the Internet of things era is one of the most required aspects. An information security in the environment monitoring system is very important, the information sent from the wireless sensor network to the Data Center must be completely secure and only users with the access right can read the contents of the information. To secure the contents of the data,...
