Hardware-software Reconfigurable Techniques for Wireless Sensor Network

Abstract

Now-a-days, the industrial based real time embedded applications are highly developed and they act as a major role in the production cost and real world safety environment. In that, one of the advanced technique is that reconfigurable techniques. This technique plays a major role with wireless sensor networks for the efficient data transmissions. In recent days, most of the industrial applications are works to minimize the size and cost of device. The foremost improvement of the reconfigurable technique is that it circumvents the unnecessary hang and deferral in the device performance. In modern biosphere, Field Programmable Gate Array (FPGA) is one of the supreme operative reconfigurable devices and generally used for most of the hardware and software reconfiguration applications. In this study, the exertion pacts with whatever going to make changes in the hardware and software during runtime, it should not disturb the present successively process. This is the main impartial of the study that the changes to be done in an analogous manner at the same time concentrating the cost and power transmission problems during data trans-receiving and also the results to be seen with the help of online manner via the Ethernet cable.

Wireless Sensor Network Design Methodologies: A Survey

“…It includes two reconfiguration scenarios and the MAPE (Monitor, Analyzer, Planner, and Executor) loop modules [17]. Indeed, two reconfiguration scenarios are adopted in WSN applications [18]. The first scenario is the node-level-based reconfiguration, which corresponds to hardware and software reconfiguration.…”

ANFIS Analysis of Wireless Sensor Data with FPGA

“…Thus, it is important to be able to manage these applications, monitor the network and reprogram the nodes to avoid existing problems. In general, hardware part of sensor networks include processing elements (Microcontrollers), sensors, battery and wireless communication elements which sends data from sensors to sink node that routes the data to the central management system like a gateway [2] [17]. Limited battery power, storage and computation capabilities, and security problems are limitation and disadvantages of traditional sensor nodes.…”

“…In such cases, the smart sensors can implement many intelligent functions such as pre-processing data, testing and performing complex algorithms, in addition to some communication tasks. FPGAs support reprogrammable technology which can be used for a reconfigurable sensor system [17]. They improved the efficiency of sensor systems by their architectural flexibility, re-configurability, processing capabilities, interfaces.…”
