The aim of this study is to perform a simulation of large scale Wireless Sensor Networks (WSN) working on medical diagnosis. The main feature of this WSN is its density and the fact that all sensors are in the same radio range. Our approach helps medical staff to diagnose diseases in an automatic way. In this context, each patient is equipped to a set of sensors. Each sensor is connected to a transducer...
Most of wireless sensor networks (WSN) research topics consider how to save the energy of the sensor nodes. However, in some applications of WSN, such as in the monitoring of an earthquake or forest wildfire, transmitting emergency data packets to the sink node as soon as possible is much more important than saving power. In this paper, we propose a Priority-based Hybrid Protocol (PHP) WSN model to...
The unplanned and random deployment of a Wireless Sensor Network (WSN) may impose a high node density on a specific region. This concentration can be exploited by density control mechanisms to increase network lifetime, by deactivating temporarily redundant sensor nodes. Previous approaches for density control in WSN focus in guaranteeing full sensing coverage of monitoring area. This work presents...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
