Method for multipath source routing in sensor network

The present invention relates to a multi-path source routing method in the sensor network, the sink node and a plurality of the sensor when in the node sensor network including a performing network initialization operations of each sensor node, the sensor from the control message for the network initialization nodes on the basis of the routing table is generated by collecting up neighborhood information to forward data packets through the return path formed by the upstream neighbor of the down path, and each sensor node set. According to the invention, through the network initialization process, maintaining the upward adjacent to deliver the data to the sink node on each sensor node and sink node, but by creating multiple paths to obtain this information, using a multi-path control message over to reduce the head holding reduce the routing table size of nodes in the sensor, regardless of the size of the network has the advantage of increasing the extensibility, and the energy efficiency.
