Survey on Data Collection Techniques in Wireless Sensor Networks

Abstract

In Wireless sensor networks, data are transfer from sensor node to base station. Sensor nodes are work as a sensor to sense the data from environment depends upon to its functionality and forward data to its base station. To collect data by sensor node or transfer to base station is called data collection. Data is collect by nodes either directly or multi-hop routing. In direct routing technique data is transfer directly by sensor node to base station which influences the energy consumption from sensor node because there is far distance between the sensor node and base station. In second technique multi hop-routing the data is transfer through multiple nodes to the base station, it consume less energy. In this paper discuss various data collection and routing based techniques like LEACH, MODLEACH and RFDMRP.
