Node mobility scheme in emergency multi-hop wireless network by Kangrong ZHANG, Jiming LIN, Lin ZHENG

“…When there is a segmentation phenomenon in the network,the increase in throughput easily leads to network congestion.The key problem that causes network segmentation is that there are key nodes in the network.The key nodes are public nodes of a large number of network routes,which lead to the increase of energy consumption of key nodes and the decrease of network communication efficiency.A node mobility scheme based on dependency graphs to compensate for network segmentation was proposed.Firstly,the key nodes that cause congestion in the network were determined through the dependency graph.Then,the neighboring points of the key nodes were selected.Under the condition that the topology of the nodes were unchanged,moving in the divection of the shortest connected distance to establish a backup route of the key node position.The simulation results show that compared with the existing node mobility schemes,this scheme has significant performance improvements in network connectivity,coverage and network life cycle.…”

Deployment scheme of WSN relay nodes based on artificial bee colony optimization by Kainan LIU, Xu HAN

“…In wireless sensor network(WSN),the relay node deployment performance is one of the main factors to affect network life.Aiming at the WSN with 3-demension high density,there is no existing relay node deployment schemes enhancing the network life efficiently with the constraints of hardware cost and network connectivity.Hence,a novel deployment scheme called artificial bee colony(ABC)-based relay node deployment scheme(ABC-RNDS)was proposed based on network-grid deployment method.In ABC-RNDS,double-layer topology was adopted to build WSN,which used minimum spanning tree to construct the backbone nodes of WSN,and applied ABC to extend the network lifetime by optimizing network parameters and constraining the number of relay nodes.The simulation results show that,compared to the traditional deployment scheme,ABC-RNDS can improve network lifetime significantly under constrains of cost and connectivity.…”
