ABSTRACT:
Provided is a method for selecting a broadcast routing path using a genetic algorithm in an Ad-hoc network. In the method, a plurality of nodes of the Ad-hoc network is defined as one chromosome, and the chromosome is represented with pairs of {order, power} in each node. Child nodes are created by performing an order based crossover and a power based crossover with respect to parent nodes neighboring to a source node. A mutation operation is performed with respect to the parent nodes and the child nodes. Relay nodes are determined by converting order and power information of each node of the chromosome into routing tree information. Power of the relay nodes is determined. A broadcast routing path is selected using the number and power of the relay nodes.
