A multi-cluster-head based clustering routing algorithm is researched and realized in order to achieve better balance the energy consumption of wireless sensor network nodes as well as promote the stability and extend the service life of the network. By taking cluster as the basic unit, it divides the wireless sensor network into multiple clusters, each of which includes a main cluster head node,...
This paper deals with influence of the fusion of part of the related data in WSN on the energy consumption of network clustering based on the hypothesis that the data packets transmitted by cluster-head node after data fusion are the minimum with the rate distortion function theory. The study shows that node energy consumption largely depends on its location: although some nodes are comparatively...
In this paper, a cluster-based data gathering algorithm ECDGA for mobile wireless sensor networks is proposed. Network model includes mobile nodes and fixed nodes. The former constructs cluster by self-organizing according to the distance between the fixed nodes nearby and themselves. The latter selects cluster head in accordance with the residual energy and location of the mobile nodes around, and...
Hundreds or thousands of sensor nodes are deployed to WSNs (wireless sensor networks). They contribute to collect data in various environment, but with limited battery power. There are some deficiencies in WSNs. Many sensors share limited wireless channel bandwidth, which leads to some sensors lose their data sent to cluster-head. Many cheap sensors are equipped to nodes for low cost and they usually...
