Adaptive energy-saving routing algorithm for inter-clustering communications in WSN by Wen-feng LI, Lian-feng SHEN, Jing HU

“…An adaptive routing algorithm was proposed for saving nter-clustering communication energy in wireless sensor networks (WSN).In the network,the end-to-end route discovery mechanism was based on the primary principle of the minimum communication costs.An algorithm was prop sed for inter-clustering communication optimization by adaptively selecting the most energy-efficient communication mode among direct,relaying and cooperative communications.The proposed routing algorithm guarantees that the source node can discover the minimum or sub-minimum energy consumption route to the base station.It also decreases the probability that the communications are interrupted due to the coverage holes.Compared with the other routing algorithms,the simu tion results show that the proposed routing algorithm makes WSN consume less energy in each round under the same throughput and bit error ratio (BER).It can also prolong the network lifetimes and operation times under the different node densities.…”

One-bit maximum likelihood algorithm for sensor networks in non-ideal channels by Nana WANG, Zhaoting LIU, Yingbiao YAO

“…Wireless sensor networks typically consist of wireless sensor nodes that are distributed in a certain spatial range.In general,the energy storage,computing and communication capabilities of nodes are extremely limited.Direct transmission of the sampled signals of the various nodes to the fusion center will result in more energy consumption and greater network communication load.If the sampled signal value of each sensor node is compressed into a one-bit measurement value and then transmitted,the energy consumption and the communication load can be greatly reduced.The parameter estimation problem based on one-bit measurement of sensor networks in multiplicative noise environment was studied.Considering the non-ideal binary channel with interference between the node and the fusion center,a parameter estimation algorithm based on maximum likelihood was proposed,Cramér-Rao lower bound of the parameter estimation was analyzed,and the effectiveness of the algorithm was verified through a series of simulation experiments.…”
