Abstract

A cognitive mobile wireless system is disclosed that enhances connectivity of a mobile device moving among heterogeneous networks, by selecting advantageous links.

Claims

1. A cognitive wireless system for a mobile node (MN) and a user thereof, to operate dynamically with heterogeneous networks, comprising:

(a) a first network with characteristics, and a second network with different characteristics;

(b) a first Mobile Node (MN) and a policy of using said first network as a default and wherein said first Mobile Node (MN) operates on said policy;

(c) said first Mobile Node (MN) having an associated first application with requirements;

wherein said first Mobile Node (MN) monitors the contextual factors of (i) link assessment factor associated with said first default network and link assessment factor associated with said second network; and

one or more of (ii) environmental factor, (iii) application factor, and (iv) cost factor; and

wherein said first mobile node (MN) has a link selector that operates on said policy in real time on said contextual factors, and selects said second network to use instead of said first default network by taking into account the user'"'"'s intentions as inferred by those of said contextual factors whose values are derived by the user'"'"'s mobility actions with said first Mobile Node (MN);

wherein said user'"'"'s mobility actions with said first mobile node (MN) include the speed or location of said first mobile node (MN); and

(d) a seamless mobility agent (SMA) to act as a virtual network interface (VNIC) which acts as a proxy for said first mobile node (MN) when interacting with its correspondent node (CN), wherein said first mobile node (MN) has a mobile agent (MA) that has an IP Mobility layer, and said seamless mobility agent (SMA) has a corresponding IP Mobility Home Agent (HA), and said first mobile node mobile agent (MA) registers a plurality of care-of-addresses (CoAs) with said IP Mobility Home Agent (HA), and said mobile agent (MA) sends a multi-streaming message by redundantly and simultaneously streaming the message using two of said plurality of care-of-addresses (CoAs),

wherein said mobile agent (MA) sends said multi-streaming message upon detection of degradation of said contextual factor of link assessment associated with said first default network, and

wherein said sending of multi-streaming message is terminated upon detection of the regaining of an acceptable said contextual factor of link assessment associated with said first default network, and the system then sends a message in a single stream to a single care-of-address (CoA) of said plurality of care-of-addresses (CoAs).

2. The system of claim 1, wherein said first Mobile Node (MN) is provided Global Positioning System (GPS) information about its location and wherein said mobile agent (MA) sends said multi-streaming message in response to said first Mobile Node (MN) location.

3. The system of claim 1, wherein said first Mobile Node (MN) is provided information about its acceleration and wherein said mobile agent (MA) sends said multi-streaming message in response to said first Mobile Node (MN) acceleration.
