A Survey on Sink Based Multipath Routing Protocols in WSN
Wireless Sensor Networks are the large collection of sensor networks which used to sense the physical and environmental condition and send the sensed data to the base station to the relay nodes. After sensing the data, data aggregation is the next phase of a WSN. Data aggregation is used for minimizing the cost of the network. And the aggregated data transmitted to the base station for further purpose. Due to the limited range and power capability of sensor nodes the transmission is done by multipath routing. Various multipath routing protocols are used for this purpose. This paper presents the comparison of different multipath routing protocols which used sink node for path selection.
