ABSTRACT
This chapter presents the following approaches of optimally configuring and clustering a wireless sensor network (WSN): To optimally configure a WSN by time matrix and To optimally cluster a WSN into a multitier architecture. In the existing clustering algorithms, the distance between regular node and cluster head (CH) is normally used as a unique metric for regular nodes to choose CH to join. A novel matrix Time is introduced and is used as a new criterion for optimally assigning the regular nodes into clusters. The chapter discusses the calculation of network lifetime into an optimizing problem; we then give procedures on how to achieve its solution. It provides a distributed approach for network configuration in WSNs with the optimal energy efficiency (DOCE). Simulation results demonstrate that DOCE significantly outperforms Low-Energy Adaptive Clustering Hierarchy (LEACH) and ad hoc network design algorithm (ANDA). The chapter proposes an energy-efficiency optimized distributed multitier clustering algorithm for WSNs.
