Sensing range is an important measure of the performance in Wireless Sensor Networks (WSNs). The sensing range which is determined by detection probability depends on the nature of the propagation path, transmit power etc. The detection probability degrades with decreafixed transmit power scheme detection probabilityse in node spatial density and increase in level of shadowing. In fixed transmit power...
This paper evaluates energy level performance of error control strategies in Wireless Sensor Networks (WSNs). More precisely Forward Error Correcting (FEC) and Automatic Repeat Request (ARQ) technique are studied for a square grid WSN. ARQ scheme is compared with FEC scheme in terms of Packet Error Rate (PER), energy efficiency and total energy spent to communicate packetized data. The impact of node...
This paper evaluates energy level performance of three packet delivery schemes in a Wireless Sensor Networks (WSN) in multipath Rician fading channel. Three different information delivery mechanisms are investigated using regenerative relays with or without error correction capability. Energy consumption for successful delivery of a data packet for each mechanism is evaluated and compared under several...
