The advancement of Wireless Sensor Networks (WSNs), necessitate optimisation of their algorithms and their performance. More specifically, network coverage and preservation of nodes energy to increase the network's lifetime are among the core objectives of routing and clustering methods. This thesis constitutes of a literature review of WSNs' routing protocols in a categorised manner followed by proposing an energy efficient and QoS aware paradigm (PUSH) for flat network that outperform other similar paradigms in terms of collective delay and energy dissipation within the network. We have proposed a new clustering model, known as Energy Aware and Address Free Clustering (EAAFC) in which, no global addressing is required. In other words, nodes are assigned with an ID, based on local information. EAAFC clusters nodes with minimum number of cluster heads which in turn results in less in network energy consumption. Cluster heads are then re-elected frequently based on nodes' energy and distribution. EAAFC does not require geographical location of nodes nor time synchronisation. We compare performance results of our proposed clustering model, against two of well received algorithms, namely LEACH and EECF to demonstrate the advantages of EAAFC. In chapters 1 and 2, the major routing protocols have been studied over the years of research and strength and weaknesses of each protocol has been scrutinised. Further, objectives, motivation and methodology of the research are discussed. In chapter 3 and 4 the proposed routing paradigm for flat networks (PUSH) as well as the clustering protocol, EAAFC, and its advantages over other protocols is discussed in depth. Several scenarios based on similar well-known routing protocols have been implemented and tested to use as comparison and to evaluate the performance of paradigm and protocol presented in this thesis. These scenarios have been implemented in the simulator environment. The simulation results confirm the theoretic evaluation and support that PUSH and EAAFC outperforms the other protocols in compared criteria as they can achieve less latency, better coverage, preserve more energy and achieve more equally distributed energy dissipation across the network which result in longer network life time and full functionality.
