N2 - 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 bit error rate (BER) and packet error rate (PER) of the received signal are evaluated and energy required for successful delivery of information to the sink considering single hop communication is estimated. The effects of node density, correlation amongst interferers and power control error on BER, PER, average number of retransmission and energy consumption for successful reception of a packet at sink in a single hop are investigated. Analytical results are verified through simulations.
