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...
The paper evaluates the performance of a CDMA based static wireless sensor network (WSN) in terms of bit error rate (BER), considering correlation amongst signal and interferers in large scale fading environment. We assume each node is power controlled while antenna diversity is present only at the sink. The effects of node density, and number of antennas used for spatial diversity on BER is investigated...
The paper evaluates the performance of a CDMA based wireless sensor networks (WSN) with layered architecture in terms of energy consumption for successful transmission of data packets, considering only correlation among interferers in shadowed environment. We consider a model of interference at the sink for a layered architecture of CDMA based WSN with two kinds of interference, multiple access interference...
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...
