In this paper, we analyze the performance of a single hop CDMA based wireless sensor network (WSN) using receiving antenna diversity at sink in terms of outage probability and bit error rate (BER). Correlation amongst signal and interferers is considered in large scale fading environment. We assume each node is power controlled while antenna diversity is present only at the sink. Energy consumption...
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 the optimal packet size for successful transmission of data packets in a CDMA based wireless sensor networks with layered architecture. Energy efficiency is chosen as an optimization metric. Correlation amongst signal and two kinds of interferers (Multiple Access Interference and Node Interference) in shadowed environment has been considered. An appropriate energy model is considered...
