1. A method for routing and network formation of a network system having a source node, a destination node, and a plurality of independent nodes, the method comprising the steps of:

  • setting multi forward paths from the source node towards the destination node to which the source node sends out a route request message;

    setting a backward path in which the destination node in receipt of the route request message sends out a route reply message to the source node along one of the set multi forward paths, wherein a route is formed as a most suitable path between the source node and the destination node by a master-slave switching through the set backward path; and

    confirming the one of the set multi-forward paths within a predetermined time period,wherein the master-slave switching switches a master node to a slave node,wherein when the one of the multi forward paths are not confirmed within the predetermined time period, links on unselected forward paths are parked,wherein the route request message is a routing trigger that initiates an Inquiry operation in the source node to find and connect neighboring nodes, and wherein the Inquiry operation depends upon a generated random number.
