HONG Gang, TANG Bao-ping, PEI Yong. Approximation Algorithm of Minimum Cover Set in WSN Based on Pixels of Sensing Region[J]. 2012, 29(12): 120-123.DOI:
This paper presents an approximation algorithm of minimum cover set based on pixels of sensing region.The node sensing area is discredited into a series of pixels
and a node is redundancy if all of its pixels are covered by other nodes.So we can get the maximum redundancy node set
and also its complement — the minimal cover set.The feasibility and performance of the algorithm is discussed
correctness of the algorithm was evaluated by experiment.Compared experimental data show that its minimum cover set is equivalent to the CVT algorithm
and its time complexity is superior to the CVT algorithm.
