WirelessHART, an international standard of wireless industrial networks, adopted the concept of graph routing to meet the requirements of short latency and high reliability. However, WirelessHART networks also require longer network lifetimes when implemented for industrial applications. Designing a reasonable form of graph routing is one method to achieve a balanced consumption of network energy...
In view of the wireless sensor network routing LEACH protocol ignored the election of cluster head nodes energy, node density and relative information of base station location, proposes a improved clustering routing algorithm based on energy, density and location information of Sink. Introduces the residual energy and density factors in the threshold formula, makes the cluster heads for the entire...
In order to prolong the lifetime and reduce the transmission delay of Wireless Sensor Networks (WSNs), we propose a novel Hierarchical Routing Protocol based on Dynamic Weight (HRPDW) for WSNs. In our HRPDW, first considering the important parameters of both residual energy and transmission delay, we set the dynamic weight; second, every sensor node stores the dynamic weights of its several adjacent...
ZACA-EEC (Zigbee Ant Colony Algorithm Energy Efficient Cluster) routing protocol is proposed to replace AODV in Zigbee with the aim of increasing reliability for mine equipment monitoring in this paper, which can prolong the lifetime of network remarkably. Taking hydraulic support as an example, the distribution of monitoring nodes can be simplified as chain hierarchy topology, then Free-space model...
In Wireless Sensor Networks with a clustered-hierarchical structure, Cluster-Head (CH) nodes function as gateways between the sensors and the Base Station (BS). The energy dissipation of the sensors can be reduced by optimizing the load balance within the clustering hierarchy. This paper proposes a three-layer clustering scheme in which the system lifetime is extended by adding an additional layer...
Clustering is an effective approach to hierarchically organizing network topology and to prolong the lifetime of a wireless sensor network. Current clustering protocols usually utilize two techniques: selecting cluster heads with more residual energy and rotating cluster heads periodically to distribute the energy consumption among nodes in each cluster. Most of the researches in this field has focused...
