This paper proposes two Markovian models to analyze the performance of IEEE 802.11p EDCA mechanism for vehicle-to-vehicle (V2V) infotainment applications. The first model describes the backoff procedure and is used to compute the transmission probability of each access category (AC) while the second illustrates the contention phase after a busy channel and is used to derive the probability of collision...
Having seamless Internet connection is highly desirable for wireless sensor network (WSN). IPv6 offers the most promising solution to deal with the large quantity of nodes or "things". This demonstration presents a versatile research and development (R&D) or prototyping platform, on which we implement generic hardware and software framework for sensing/monitoring as well as remote control...
The monitoring and control of crops in precision agriculture sometimes requires a high collection frequency of information (e.g., temperature, humidity, and salinity) due to the variability in crops. Data acquisition and transmission are generally achieved thanks to wireless sensor networks. However, sensor nodes have limited resources. Thus, it is necessary to adapt the increase in sampling frequency...
In sensor networks, several applications such as habitat monitoring and moving objects tracking, require the knowledge of nodes positions. Position estimation most often includes errors due to the measurements of distance and incoming angles between neighbors. Erroneous positions are propagated from a node to other nodes exacerbating the degree of errors in the estimation of the positions of these...
