Wireless communication presents the most attractive sign of development in this decades. It contributes to the appearance of Wireless Sensor Network (WSN) which is invented in order to increase the supervision capacity for such phenomenon. It gets more regard from both the customers and the research society. (WSNs) is composed from numerous wireless sensor nodes which suffer from a very serious energy...
Topology topic has gained additional and special interest in the field of Wireless Sensor Networks (WSN). While WSN deployments are in general optimized by the known fundamental network topology, another trend is to enhance WSN by managing the network topology. Many propositions have been tested in this field, like topology directed routing, cooperating schemes, sensor coverage based topology control...
Energy consumption represents a key element in the Wireless Sensor Networks (WSNs) design. Several factors can cause energy over consumption such as mobility, node position (relay or gateway), retransmissions... The network topology can also be a major cause of energy waste: a transmission in 1-hop requires a high energy, a transmission in K-hops requires a lower energy, even though, it can damage...
Based on the principles of wireless mesh network (WMN), clustering of wireless sensor network (WSN) was reconstructed by combination of WMN and WSN into a topology named wireless mesh sensor network (WMSN). In terms of Voronoi diagram and Delaunay triangulations of computational geometry, central degree theory of complex network and heuristic algorithm based on mean weight of communication energy,...
Topology control is an important research direction in wireless sensor networks, by selecting a good topology control mechanisms is good for improving the efficiency of network communication and prolonging the life cycle of network. Based on the analysis algorithms of TopDisc algorithm, this thesis introduces an improved algorithm - proposes a topology control algorithm based on energy and power control...
