Abstract
The paper evaluates the energy level performance of CDMA wireless sensor networks (WSN) with a new error control strategy using BCH coding following hybrid ARQ. The performance of the proposed scheme is compared with simple ARQ using CRC and with an existing HARQ-I employing BCH code when applied to CDMA based WSN in terms of energy consumption for successful transmission of fixed length packet. Two kinds of interference namely multiple access interference (MAI) and node interference (NI) are considered. Packet error rate (PER) and energy required for successful delivery of information to a sink considering single hop communication is estimated. The effects of several network parameters such as node density, correlation amongst interferers, power control error (pce) on PER, average number of retransmissions, energy consumption for successful reception of a packet at sink are investigated and energy efficiency in a single hop transmission are estimated and compared for different error control strategies. Analytical results are verified through simulations.
Keywords: HARQ, BCH coding, Wireless CDMA Sensor Network (WCSN), Correlation.
