Abstract

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 calculating the requirement of energy for successful delivery of information between two nodes. The effects of node density, correlation among interferers, power control error (pce) on PER, average number of retransmission and energy consumption for successful reception between two successive nodes are investigated. Analytical results are supported by simulation results.
