iFrag: interference-aware frame fragmentation scheme for wireless sensor networks

Abstract: In wireless sensor networks, data transmission reliability is a fundamental challenge due to several physical constraints such as interference, power consumption, and environmental effects. In current wireless sensor implementations, a single bit error requires retransmitting the entire frame. This incurs extra processing overhead and power consumption, especially for large frames. Frame fragmentation into small blocks with individual error detection codes can reduce the unnecessary retransmission of the corre… Show more

“…The authors of Seda claim that a block size of 20-25 bytes provides near-optimal throughput. However, this is not always correct because it highly depends on both the channel condition and the Bit Error Ratio (BER) as we show in [11]. A similar static partial packet recovery technique, but for wireless local area networks, was proposed in [13].…”

“…iFrag [11] and Hi-Frag [12] are two recent dynamic frame fragmentation schemes that were specifically designed to suite WSNs. iFrag [11] is a dynamic block size allocation protocol that adapts the block size based on current channel conditions, leading to lower block loss rates and a significant reduction in block retransmissions.…”
