Abstract

In this paper, we propose a distance-adaptive robust communication scheme which is based on existing IEEE 802.15.4 protocol without additional control frame overhead. The key mechanism of the proposed scheme provides the dynamic tuning of the BE value and frame retransmission opportunities according to the hop distance to the sink node. We also propose a new robust route maintenance scheme for avoiding and mitigating congested nodes during communication sessions.
