One of the most critical issues in designing wireless sensor networks is to minimize the energy consumption for longevity. Most of topology control algorithms assume homogeneous wireless nodes with uniform maximum transmission ranges, and can not directly applied to heterogeneous wireless multi-hop networks in which the maximum transmission range of each node may be different. In this paper, we present a localized clustering algorithm for heterogeneous networks. In this algorithm, each node in the same cluster selects a set of neighbors based on the locally collected information. Simulation results show that this algorithm can reduces the average degree of cluster-head and the average translate power.
