A Clustering Algorithm Based on Location Aware in Wireless Sensor Networks
Haifeng Hu · Journal of Nanjing University of Posts and Telecommunications · 2008
A novel clustering algorithm based on location aware in wireless sensor network is proposed in order to solve the problem of collecting spatial correlated data with energy validity.According to the user-provided error-tolerance threshold and sensing data similarity matrix based on location information,the algorithm performs unsupervised data mining task and then divides the monitoring range into several equivalent information ranges.Only one node per equivalent range is selected as the cluster-head by present maximal remainder energy.A mobile agent is used to collect sensing information of cluster-heads.This mechanism reduces the amount of transmission data and saves energy efficiently.
