Vasu Jolly, Shahram Latifi · International Conference on Wireless Networks · 2006
Wireless sensor networks illustrate enormous potential for increasing the information availability to people in many consumer and industrial applications such as smart buildings, target tracking, data collection, rescue missions, national security, monitoring disaster prone areas, managing inventories, monitoring health care, environmental studies, and home security . Much research effort has been made in the field of wireless sensor networks, in both academia and industry igniting the thrust to realize its unlimited applicability in various application fields. The network topology in a WSN may change drastically since nodes can be added and removed easily. The data from sensor nodes is gathered by the sink. The sink may be connected to the outside world thorough Internet or satellite. Sensor nodes will be scattered over a sensor field, so the locations of sensor nodes in the field cannot be predetermined. This paper continued from the previous part classifies the key routing techniques used in sensor networks. Each routing technique is studied in terms of resource usage, efficiency, applicability and scalability and the most challenging research directions are outlined. We provide a a conclusive study of different routing schemes used in routing characteristic of wireless sensor networks. Each of the routing schemes and algorithms has the common objective of trying to extend the lifetime of the sensor network.
