1. In a hybrid-cellular network, a method for converting a hybrid-cellular route to an ad-hoc route, the method comprising the steps of:
- determining if two nodes within the hybrid-cellular network are in close proximity;
determining connectivity information for the two nodes, wherein the step of determining connectivity information comprises the step of determining information taken from the group consisting of a tree route path between the two nodes, a neighbor list for each node, and an associated link quality for nodes along the tree route path;
determining an optimized ad-hoc route between the two nodes, wherein the optimized ad-hoc route between the two nodes does not involve the network coordinator; and
converting the hybrid-cellular route to an ad-hoc route by instructing the two nodes to communicate via the optimized ad-hoc route.

Abstract
In order to set up efficient routes between two closely-located nodes an optimized route for two nodes within a hybrid-cellular network (HCN) is achieved by converting an HCN route to an ad-hoc route. Thus, a node within the communication system may originally be communicating with another node via an HCN route and then instructed to switch to a more efficient ad-hoc route for communication with the node.

5. In a hybrid-cellular communication system, a method for converting a hybrid-cellular route to an ad-hoc route, the method comprising the steps of:
-
determining if the two nodes are in close proximity; determining route information for the two nodes, wherein the step of determining route information comprises the step of determining information taken from the group consisting of a tree route path between the two nodes, a neighbor list for each node, and an associated link quality for nodes along the tree route path; determining an optimized ad-hoc route between the two nodes based on the route information, wherein the optimized ad-hoc route between the two nodes comprises a ad-hoc route having a least amount of hops, wherein the optimized ad-hoc route between the two nodes does not involve the network coordinator; and instructing the two nodes to convert the hybrid-cellular route to the ad-hoc route by assigning the two nodes the optimized ad-hoc route. - View Dependent Claims (6, 7)

8. A network coordinator existing within a hybrid-cellular network (HCN), an apparatus for creating an ad-hoc route, the apparatus comprising:
-
logic circuitry determining an optimized ad-hoc route between two nodes utilizing a hybrid-cellular route, the optimized route being based on route information, and wherein the optimized ad-hoc route between the two nodes comprises an ad-hoc route having a least amount of hops, and wherein the optimized ad-hoc route between the two nodes does not involve the network coordinator, and wherein the route information is taken from the group consisting of a tree route path between the two nodes, a neighbor list for each node, and an associated link quality for nodes along the tree route path and a transmitter instructing the two nodes to change from an HCN route to the ad-hoc route. - View Dependent Claims (9)
