Abstract
Provided is a method of performing a routing and allocating a resource in a wireless sensor network. The method includes electing one or more cluster heads, each representing each of one or more clusters comprised of a plurality of sensor nodes, selecting a routing path between the cluster heads and the plurality of sensor nodes, selecting a frame length based on elements and distribution methods of the wireless sensor network and the routing path, forming a time slot resource allocation table for communication between the cluster heads, and exchanging the time slot resource allocation table between the cluster heads separated by one hop. The present invention can enhance the reliability of the wireless sensor network and QoS by effectively performing routing and allocating resources in such a manner that various data requirements can be satisfied.
