As an application-driven network, wireless sensor network generally requires data reliability to maintain detection and response capabilities. Although two approaches, namely, retransmission and redundancy, have been proposed to enhance data reliability, the theoretical work is required to evaluate their impact on transmission reliability and energy efficiency. In this paper, we offer a comprehensive theoretical study on packet arrival probability and average energy consumption for both… CONTINUE READING
