Define the number of nodes deployed in corona C i is N i and the number of pixels in corona C i is A i. Based on the pixel-based transmission mechanism, the number of messages for corona C i to receive and forward is (Ai+1+ Ai+2+··+AA n ) and (A i +Ai+1+···+A n ).
While the pixel-based transmission mechanism is used, the number of messages transmitted reduced to 10.
In fact, we can prove that completely balanced energy depletion is achievable with the additional help of pixel-based transmission mechanism in this article.
The residual energy of each node at the end of the lifetime is shown in Figure 7. Here, the pixel-based transmission mechanism is also applied in the VFA algorithm.
To sum up, as the duplicate sensing message is sent only once by the use of pixel-based transmission mechanism, the total number of duplicated messages saved to transmit is 12.
In addition, although δ-Push&Pull adopts a non-uniform node distribution, its network lifetime is not superior to VFA by adopting the pixel-based transmission mechanism, in which the traffic burden caused by constant data acquisition is reduced effectively.
By importing the pixel-based transmission mechanism and satisfying the node density for energy-balanced depletion condition, our approach has the smallest traffic burden in each working round, and achieves the longest network lifetime.
We present a theoretical analysis of energy attenuation in non-uniform distribution strategy, and prove that when the pixel-based transmission mechanism is adopted, a full energy balance can be achieved through the rational node distribution density.
Although the two tissue samples were physically in the same intact tissue and are structurally similar, the two images have different properties (total image and pixel sizes, contrast mechanisms and data values).
Based on this fact, the pixels of the source images are classified into three types in the updating mechanism, namely, pixels of focused significant regions, pixels of smooth regions, pixels of transition area between the focused and defocused regions.
