Wireless sensor network (WSN) is widely considered as one of the most important technologies for the twenty-first century. In the past decades, it has received tremendous attention from both academia and industry all over the world. In WSNs, topology plays an essential part in minimizing different imperatives, for example, latency, restricted vitality, computational asset emergency and nature of the correspondence. There are many types of routing protocols in WSN such as hierarchical protocols consist of LEACH and PEGASIS routing protocol. This study aims to evaluate the performance of PEGASIS and LEACH protocol using MATLAB based simulation platform. Simulation results showed better performance for PEGASIS even both protocols fall under hierarchical category. In this project describe PEGASIS a greedy chain protocol that is near optimal for a data-gathering problem in sensor networks. PEGASIS outperforms LEACH by minimizing the distance non leaders-nodes must transmit, limiting the number of transmission and receives among all nodes, and using only one transmission to the BS per round. PEGASIS protocol achieves an increases of 2 times higher than LEACH protocol in term of energy consumption. For the system lifetime PEGASIS perform 30% better than LEACH and in terms of delay LEACH introduces less delay than PEGASIS.
