METHOD FOR MULTI-PATH SOURCE ROUTING IN SENSOR NETWORK

摘要

A method for a multi-path source routing in a sensor network. In the sensor network including a sink node and a plurality of sensor nodes, the sensor network transmits data packets through a downlink route set based on a routing table generated by collecting uplink neighbor information of each sensor node from a control message for initializing a network and an uplink route formed by using uplink neighbors of each sensor node. Uplink neighbors for transmitting data from each sensor node to the sink node by performing a network initialization process and acquires the information in the sink node to generate the multi-path is maintained. As a result, it has advantages of reducing a control message overhead while using the multi-path and increasing scalability and energy efficiency by keeping a routing table small in the sensor node regardless of the size of the network.
