Data fusion is an important technology in WSN, But with the expansion of the scope object sensor and complexity increase, the fusion function is more and more complex, Energy consumption of the fusion operation is required more and more. Therefore, the energy consumption of the data fusion and the data transmission has been can't ignored already. Using the compressive sensing theory in the WSN data...
Aiming at the shortage of LEACH protocol, a new routing protocol CDS-EBRP is proposed in this paper, CDS-EBRP fully takes account of the energy consumption of individual node and entire network, a rational transmission path from nodes of network to sink node is searched, Aiming at the network topology changes which are caused by the dead of cluster head nodes, the invalidation of cluster member nodes...
Aiming at the limited resources and data transmission redundancy of WSN, this paper proposes a novel data compression algorithm based on lifting wavelet transform, gives the rational design. The algorithm distributes the computing quantity which the lifting wavelet transform requires to all nodes, eliminates extra computing and data transmission, reduces the information redundancy of network, greatly...
Cooperative diversity can be applied to energy-constrained resource-constrained wireless sensor network s to significantly reduce node energy consumption. However, cooperation synergy must be carefully selected and coordinated to practically exploit this energy saving potential. In this paper we investigate synergy choice for energy minimization algorithm in a resource-constrained wireless sensor...
