Abstract :
This paper describes an adaptive error recovery mechanism for sink-to-sensors reliable data dissemination in multi hop wireless sensor networks. The proposed error recovery mechanism(ONE) uses a cross layer variant of the negative acknowledgement(NACK) based Selective Repeat scheme for retransmissions. The mechanism is further extended to multi hop topologies by adjusting the window parameters and applying an efficient buffer management strategy. We have shown that the adaptive behavior of the scheme enables optimization of system parameters that affect the total number of packets sent in a reliable session. The analysis of the proposed scheme is given and the effect of buffer size, density and loss ratio parameters on the overall performance is shown.
