Abstract
Wide range usage of wireless sensor network in different fields is considered as important research area in these days. The development in electronic communications leads to develop a multi-purpose sensor node with low power consumption and cost. Wireless sensor systems are comprising of limited power sensors and it is difficult to recharge or replaced the sensors battery. Therefore, lifetime of wireless sensor networks is less due to more power consumption. Thus, the routing protocols that consume less amount of energy are desirable. For this purpose, various routing algorithms are proposed. The protocols based on clustering technique results low power consumption. Since radio communication consumes large amount of energy. The energy is an essential factor to be investigated. Thus, the power saving is a key issue in wireless sensor networks. Ongoing research involves designing routing protocols that requires less energy during communication thereby extending the networks lifetime. A comparison between LEACH and MODLEACH is carried out using MATLAB. Selection of efficient cluster head through which network lifetime is increased and reduces the energy consumption is a research issue.
