Focus on anti-monitoring problem of the mobile object in sensory fields, a novel dynamic heuristic anti-monitoring path searching algorithm in sensory field by combining prior property of eight-neighbor quadratic cell and A* algorithm is designed. Theoretical analyses and experimental results show that, compared with conventional works, the new algorithm has better anti-monitoring performance which...
This paper presents a new energy-efficient cooperative sensor network scheme. Cooperative nodes shift the carrier frequency of the source node, and the destination node receives the signal from the source node and the cooperative nodes as a standard orthogonal frequency division multiplexing (OFDM) receiver. The maximal ratio combining (MRC) approach is applied to achieve full diversity with low complexity...
