Abstract: Energy consumption is the main concern when planning for operation of the Wireless Sensor Networks (WSNs) equipped with limited energy resource. It is essential to design and develop energy efficient protocols in order to maximize the network lifetime, while achieving the objective of the given application. In this thesis, three energy efficient protocols are proposed for the extension of the network lifetime. The first protocol is the Fuzzy C-Means clustering protocol (FCMCP), which is designed to achieve more uniform cluster formation for cluster-based WSNs, thereby the load traffic within each cluster is balanced, and communication distances of the sensor nodes are minimized. Further improvement is achieved by adopting an evolutionary optimization method called Harmony Search Algorithm (HAS) to develop the HSA clustering protocol (HSACP). The HSACP optimizes both the cluster formation and the cluster head selection of the WSNs. The third protocol is a tree-based protocol using Intelligent Water Drops (IWD) algorithm. The IWD algorithm is adopted to construct an optimal data aggregation tree in order to transfer data efficiently. In additions, a design framework is also introduced in this thesis that enables practical implementation of the FCMCP and HSACP for real-life applications.
