Clustering techniques have been proposed to construct hierarchies of nodes inside Mobile Ad hoc NETworks (MANETs) thereby increasing their scalability and manageability and reducing the amount of maintained routing information. Herein, the authors introduce a distributed clustering algorithm that uses both location and energy metrics for cluster formation. Their proposed solution addresses cluster stability, manageability and energy efficiency issues. Unlike existing active clustering methods, their algorithm relieves the network from the unnecessary burden of control messages broadcasting, especially for relatively static and quasi-static network topologies. The efficiency, scalability and competence of their algorithm against alternative approaches have been demonstrated through simulation results.
