Design Analyze And Implement Wireless Sensor Network Performance - IJRTER

 

Wireless sensor networks (WSN), also known as sensor and actuator networks (WSAN) are spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure, etc. and to cooperatively pass their data through the network to a main location. The more modern networks are bi-directional, also enabling control of sensor activity. The development of wireless sensor networks was motivated by military applications such as battlefield surveillance; In today such networks are used in many industrial and consumer applications, such as industrial process monitoring and control, machine health monitoring, etc.These Sensor Nodes communicate with each other through various protocols. The problem of the conventional method is, during gathering of sensed data each node transmits its sensed data directly to the base station for which it will deplete its power quickly. In hierarchical structure higher energy nodes are used to aggregate and send the information whereas low energy nodes are used to sense the data. This is an energy efficient routing protocol which improves network lifetime Example- LEACH, TEEN, A.PTEEN. Among them clustering based hierarchical protocol, proves to be most feasible for energy efficient routing in wireless network. Some of them are LEACH (Low energy adaptive clustering hierarchy) PEGASIS (Power efficient gathering in sensor information system) TEEN (Threshold sensitive energy efficient sensor network protocol) APTEEN (Adaptive threshold sensitive energy efficient sensor network protocol).
