| Summary: | Wireless sensor networks (WSNs) consist of thousands of tiny nodes having the capability of sensing, computing, wireless communications, and variety of application scenarios including medical application, military, home security and so on. Many routing, power management, and data dissemination protocols have been specifically designed for WSNs where energy consumption is an essential design issues. Energy is a critical resource in WSNs and system lifetime needs to be prolonged through the use of energy-aware strategies during system operation. Routing in WSN is very challenging due to the inherent characteristics that distinguish these networks from other wireless network like mobile ad hoc networks or cellular networks. Many routing protocols have been specifically designed for WSN. This thesis is focus on the performance of two hierarchical routing which is LEACH and PEGASIS in terms of energy consumption, system lifetime and time taken to complete the rounds. The simulation experiments are done by using network simulator produce in MATLAB. From the results it can be deduced, that the PEGASIS gives a better performance in terms of energy dissipation and network lifetime compare to LEACH. |
