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 the end-to-end performance of a CDMA based static multi-hop wireless sensor network (WSN) in shadowed environment with correlated interferers. Two different information delivery mechanisms are studied using regenerative relays with or without error correction capability. Optimal packet sizes, based on energy efficiency, are estimated for both schemes under several network conditions...
This paper evaluates energy level performance of three packet delivery schemes in a Wireless Sensor Networks (WSN) in presence of Rayleigh fading. 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...
This paper evaluates the end-to-end performance of a CDMA based static multi-hop wireless sensor network (WSN) in shadowed environment. An interference model for multi-hop is presented using correlated interferers. Three different information delivery mechanisms are studied using regenerative relays with or without error correction capability. Energy requirement for successful delivery of a data packet...
The paper evaluates the performance of a CDMA based wireless sensor networks (WSN) with layered architecture in terms of bit error rate (BER) and energy consumption for successful transmission of data packets. Correlation amongst signal and interferers in shadowed environment has been considered. Two kinds of interference namely multiple access interference (MAI) and node interference (NI) are considered...
