Wireless sensor network (WSN) hierarchical routing protocols meet the efficient communication of a large-scale network. However, many of them cannot guarantee the optimum choice of the cluster heads because of the lack of comprehensive consideration of the remaining energy of nodes, the distribution within a cluster and the distribution among clusters in the process of choosing the cluster heads....
In view of the compromise between overhead and performance, this paper proposes a MAODV-X multicast routing protocol by incorporating the excellence of Explicit Multicast with the multicast-tree based routing protocol and stable link repair in Ad Hoc network, which simplifies the MAODV multicast trees by establishing the specific routing table in intermediate nodes in order to reduce the control overhead,...
The law of how the minimum absolute eigenvalue of the Jacobian matrix varies with the load of power systems is analyzed, based on which a new approach is proposed to estimate the static voltage collapse. BPA is used to calculate power flows with the increasing loads. Using the new approached method, the critical point of the static voltage collapse can be conveniently estimated under various power...
