Integrity verification protocol based on privacy homomorphism data aggregation
Published 2014-11-01“…Secure data aggregation in wireless sensor networks can effectively prevent privacy leakage,data tampering and other issues,it also achieves efficient data transmission.An integrity verification protocol based on privacy homomorphism data aggregation (IV-PHDA) was presented.The protocol uses homomorphism encryption to ensure data privacy,then it used random detection nodes to detect the integrity of the aggregated results to verify whether the aggregation node faithfully transmit each data packet.The theoretical analysis and simulation comparison verify the performance of the algorithm,the results show that this protocol can detect data integrity through transmission,and achieve better privacy protection and higher data accuracy.…”

Adaptive energy-saving routing algorithm for inter-clustering communications in WSN
Published 2012-03-01“…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.…”
