Design Analyze And Implement Wireless Sensor Network Performance - IRJET

 

Wireless sensor networks (WSN), sometimes called wireless 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 such as industrial process monitoring and control, machine health monitoring, and so on. 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. Enhanced PEGASIS is an energy efficient routing protocol which improves network lifetime and calculate distance between the nodes Example- LEACH, TEEN, APTEEN. Parameters on which Enhanced PEGASIS are node lifetime, energy consumption/dissipation, residual energy and distance between the nodes. Area monitoring is a common application of WSNs. In area monitoring, the WSN is deployed over a region where some phenomenon is to be monitored. A military example is the use of sensors detects enemy intrusion; a civilian example is the geo-fencing of gas or oil pipelines the medical applications can be of two types: wearable and implanted. Wearable devices are used on the body surface of a human or just at close proximity of the user. The implantable medical devices are those that are inserted inside human body.
