Down-hole node energy-saving method based on hotspot areas

Номер: CN104883698A
Принадлежит:

The invention provides a down-hole node energy-saving method based on hotspot areas, and belongs to energy-saving methods for a down-hole wireless sensor network. The down-hole node energy-saving method based on the hotspot areas includes: statistics of the down-hole hotspot areas is conducted, the hotspot areas in a period are determined, the statistics of the conversion between the hotspot areas is conducted, the transition probability of the hotspot areas is calculated by the adoption of a Markov process, and the control of the opening of the hotspot area nodes and the closing of non-hotspot area nodes is realized via the energy-saving method. Non-hotspot areas are areas in which a few miners are distributed at present or even without any personnel, multimedia sensor nodes of the hotspot areas need to be mainly monitored, nodes of the non-hotspot areas can be partly closed on the premise of keeping connectivity, the energy of the nodes is wasted by the monitoring of the down-hole non-hotspot ...

Wireless sensor network clustering routing protocol based on residual energy and communication cost

Номер: CN104883301A
Принадлежит:

A wireless sensor network clustering routing protocol based on residual energy and communication cost belongs to the field of wireless sensor network clustering routing protocols. All the nodes of the routing protocol are candidate cluster heads. A cluster head is selected from the candidate cluster heads. When all the nodes of each round have data to transmit and a sink node is under initial energy of a sensor node, the residual energy of the sensor node is estimated according to the clustering situation of each around. A cluster head selection algorithm is implemented by the sink node. In the cluster formation stage, the sink node sends clustering information to all the nodes in a network, wherein the clustering information includes whether a node is a cluster head or not and next-hop routing information of the cluster head when the node is a cluster head, and when a node is a member node, the clustering information indicates which node the cluster head node is. In the communication stage ...
