A Load Balance Clustering Algorithm for Heterogeneous Wireless Sensor Networks

摘要

In order to balance power usage in heterogeneous sensor networks, the LBGC (Load balancing group clustering) strategy is proposed based on the clustering model. The LBGC protocol periodically selects cluster heads and implements dynamic route calculation according to the condition of energy distributing of network, which could make full use of the heterogeneous energy to realize load balance. Simulation results show that LBGC scheme effectively balances the energy consumption among network nodes and achieves an obvious improvement on the network stability region.
