First Claim
Patent Images
1. A hand-off method comprising:
- detecting edge nodes located at edges of a mobile ad-hoc network (MANET);
retransmitting, at the detected edge nodes, an Internet gateway advertisement message (IGAM) at a new period; and
performing a hand-off of a mobile device moving from an infrastructure network to the MANET using the retransmitted IGAM.

Abstract
A hand-off method including detecting edge nodes located at edges of a mobile ad-hoc network (MANET); retransmitting, at the detected edge nodes, an Internet gateway advertisement message (IGAM) at a new period; and performing a hand-off of a mobile device moving from an infrastructure network to the MANET using the retransmitted IGAM.

11. A hand-off method comprising:
-
adjusting a period of an Internet gateway advertisement message (IGAM); and
retransmitting, at edge nodes of a mobile ad-hoc network (MANET), the Internet gateway advertisement message (IGAM) with the adjusted period. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A method of detecting edge nodes of a mobile ad-hoc network (MANET), the method comprising:
-
broadcasting an Internet gateway advertisement message (IGAM) and an identifier (ID) indicating a number of times the IGAM is sequentially broadcasted from the Internet gateway to an intermediate node in the MANET; and
establishing a reverse route from the intermediate node to the Internet gateway and retransmitting the received IGAM from the intermediate node to a one-hop node;
wherein the intermediate node is detected as one of the edge nodes in response to the intermediate node not receiving a message from another intermediate node having a greater hop count. - View Dependent Claims (19, 20, 21)
