Problems solved by technology

Regular user-mode AODVs are more flexible than kernel-mode AODVs, but perform poorly and are associated with increased processing requirements
Likewise, neither kernel-mode AODV nor user-mode AODV can perform "out-of-network" data packets (e.g., data packets sent from an AODV node without Internet connectivity to an Internet destination, from an Internet source entity to a Internet-connected AODV nodes' data packets, etc.), thus limited to routing nodes in the AODV network 100, as described above with respect to FIGS. 1 to 3

Embodiment Construction

[0033] As discussed in the Background of the Invention section, conventional Ad-hoc On-Demand Distance Vector Protocol (AODV) networks cannot route data packets from AODV nodes that do not have an Internet connection to Internet destination entities, and conventional Internet source entities cannot Data packets cannot be sent to AODV nodes that are not directly connected to the Internet. Therefore, the exemplary embodiment of the present invention which will now be described is directed to an addressing scheme which allows Internet messages to be routed to any desired AODV node within the AODV network through an AODV node within the AODV network having an Internet connection , and / or route Internet messages from any desired AODV node within the AODV network.

[0034] FIG. 4 shows an AODV network 400 according to an exemplary embodiment of the present invention.

[0035] In the exemplary embodiment of FIG. 4, AODV network 400 includes nodes 1, 2, 3, 4, and 5 having coverage ar...

Abstract

The invention provides a method to route data in wireless communication system (400, 430). In the method and system, if at least one node in MANET contains the connection with outer or device, and the data group can be routed to any node in mobile Ad-Hoc network (MANET) (400) which runs Ad-Hoc according to distance vector protocol (AODV), outer connection or device (internet entity) (430), and / or can group said node and outer connection or device. So, single connective MANET node (node 2) can share outer connection with unconnected node (node 1, 3, 4, 5).

Description

technical field [0001] Exemplary embodiments of the present invention relate generally to methods of routing data, and more particularly, to methods of routing data between Internet-connected entities and non-Internet-connected nodes. Background technique [0002] Mobile Ad-Hoc Network (MANET) routing protocols relate to protocols for routing messages between mobile devices. An example of a MANET routing protocol is the Ad-hoc On-demand Distance Vector (Ad-Hoc On-demand Distance Vector, AODV) protocol. AODV allows the mobile devices or nodes to pass messages through their neighbors to nodes with which the mobile devices or nodes cannot communicate directly. AODV does this by discovering the routes through which these messages can travel. AODV ensures that these routes do not contain loops (eg, one or more duplicate nodes), and does its best to find the shortest possible route (eg, based on delay, number of nodes visited, or number of hops, etc.). AODV is also able to hand...
