Covering Set-Based Inner-Cluster Data Aggregation Scheme for Wireless Sensor Networks
Jiang Hong Guo, Yu Dong Luo · Applied Mechanics and Materials · 2013
For reducing the communication overhead of data aggregation, authors proposed an covering set-based inner-cluster data aggregation scheme for wireless sensor networks. The network is clustered upon deployment; nodes achieve the inner-cluster neighbors’ identifiers by information exchanging and transmit the list of inner-cluster neighbors to the cluster head to help the cluster head deducing the inner-cluster covering set. Each node selects a neighbor form inner-cluster covering set as reference point and keeps silent if it has the same reading with reference point. Simulation shows that the proposed scheme lowers the communication overhead of data aggregation effectively.
