In this paper, we highlight the extent of the effects of topo-logical specificities on the deployed solutions, which can be useful to refine already proposed models as well as to carry out protocol tuning or adjustments. We present, an intensive experimental study on wireless Link Quality Indicator (LQI). Using Moteiv's Tmote Sky sensors, we deployed(More)
In this paper, we propose two database updating models for homogeneous and auto configurable sensor network deployed in a truck without base station. In the first model, a Virtual Base Station (VBS) is periodically elected to act as classical base station for a given period of time. VBS election algorithm is based on the remaining energy level of each node(More)
—Network topology plays a significant role in the design and performance of sensor networks. The IEEE.802.15.4 standard is designed for Low-Rate Wireless Personal Area Networks (LR-WPAN) with most applications in the automation sector. Zigbee networks placed at the top of the above standard use two classes of devices: Reduced Functional Devices (RFDs),(More)
Recent advancements in MEMS technologies and development in the area of low power microcontrollers have resulted as implementation of wireless sensor networks in real life problem solving in areas like traffic monitoring, patient monitoring , battlefield surveillance. These wireless sensors are very small in size and are operated at low power for low data(More)
We propose a rapid cluster formation algorithm using a thinning technique : rC-MHP(rapid Clustering inspired from Matérn Hard-Core Process). In order to prove its performance, it is compared with a well known cluster formation heuristic: Max-Min. Experimental results show that rC-MHP outperforms Max-Min in terms of messages needed to choose the cluster(More)
Cyclooxygenase (COXs) and Lipoxygenase (LOXs) pathways are the two major enzymatic pathways in arachidonic acid (AA) metabolism. The term eicosanoid is used to describe biologically active lipid mediators including prostaglandins, thromboxanes, leukotrienes and other oxygenated derivatives, which are produced primarily from AA. Eicosanoids generated in a(More)
Developments in last about two decades, implementation of low power microcontrollers based wireless sensors have been increased rapidly to solve many real life problems like traffic monitoring, patient monitoring, battlefield surveillance. Wireless sensor nodes are very small in size and are operated at low power for low duty applications to record the(More)
