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...
In this paper, a simulation study has been carried out to evaluate performance of joint admission and power control (JAPC) algorithms in Cognitive - CDMA Networks. Performance has been evaluated for SU in an uplink scenario of CDMA network consisting primary user (PU) and secondary user (SU). A numbers of algorithms have been investigated. Long term fading has been assumed in addition to path loss...
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...
The paper evaluates the performance of a CDMA based wireless sensor networks (WSN) in terms of outage probability and BER, considering correlation among interferers in shadowed environment. An appropriate model for the interference power, outage and BER are presented for a single hop communication. Detection probability is also evaluated in shadowed environment. The effects of node density, minimum...
The paper evaluates the performance of a CDMA based wireless sensor networks (WSN) in terms of packet error rate (PER) and energy consumption, considering correlation among interferers in shadowed environment. An appropriate model for the interference power, PER and average number of retransmission for successful delivery in a single hop communication are presented. An energy model is considered for...
Performance analysis of Multimedia Broadcast and Multicast Services (MBMS) in Cellular CDMA has been presented in this paper. Effects of soft handoff (HO) parameters have been analyzed on MBMS. Fountain code has been considered in the application layer for the broadcast services due to its rateless nature as well as to avoid a backward channel that may be needed when ARQ is used. Turbo code has been...
Effects of soft handoff (HO) on forward link performance of packet data service have been presented in this paper. Outage of packet data transmission using code division multiple access (CDMA) is evaluated. Throughput and delay have also been investigated in cellular CDMA in presence of soft HO. Influence of physical layer issues like soft HO parameters, shadowing correlation, power control error...
Performance of a packetized data transmission in cellular CDMA is analyzed in presence of soft handoff and truncated power control. The combined effects of soft handoff parameters, truncated power control at physical layer and truncated ARQ at data link layer on throughput and delay performance of packet data under a prescribed delay constrain is studied. Truncated power control improves the performance...
