Abstract:
1. A routing system using a NEtwork MObility (NEMO) protocol for reducing overheads in a network, the routing system comprising: a plurality of mobile routers roaming in the network, some of the plurality of mobile routers capable of acting as top level mobile routers and a remaining of the plurality of mobile routers capable of operationally attaching to the top level mobile routers; a central authority server capable of storing information about the top level mobile routers and the mobile routers operationally attached to each of the top level mobile routers; and a corresponding node capable of sending data packets to a destination mobile router of the plurality of mobile routers operationally attached to the top level mobile routers; wherein each of the top level mobile routers is capable of registering with the central authority server, the registering comprising sending information about mobile routers operationally attached to each of the top level mobile routers; and wherein the corresponding node is capable of locating a position of the destination mobile router operationally attached to a corresponding top level mobile router from the information stored with the central authority server; and wherein the corresponding node is capable of routing the data packets directly to the destination mobile router through the corresponding top level mobile router by using the information about the mobile routers operationally attached to the top level mobile routers stored with the central authority server; and wherein the corresponding top level mobile router sending the data packets to the destination mobile router, thereby reducing routing overheads in the network.
