文摘

We identify the limitations of the existing structured dissemination protocols in wireless embedded network systems (WENS) and propose an out-of-order, XOR enabled transmission mechanism for structured dissemination. We propose a slot length optimization model, tailored for the proposed full-slot transmission mechanism to further enhance the propagation. We incorporate the above components into ULTRA, a full-slot reliable bulk data transfer mechanism for structured bulk data dissemination. We implement ULTRA in both testbed and simulation. The results show that ULTRA outperforms the state-of-the-art works.
