Abstract:
The present invention relates to a method and system for use in providing multiple gateways within a network. A plurality of border routers (100, 200, and 300) is added preferably in between the mobile router (150) of the respective network and foreign routers so as to enable consistent connection. The border routers, among others are (100, 200, 300) suitably configured to serve as proxy advertisers for foreign routers (500), and to send out notifications with respect to their active or inactive status to the mobile router (150) of the network so as to enable the mobile router (150) to select the preeminent border router (100, 200, 300) for forwarding packets within the network.
Abstract:
A method of optimizing the quality of multicast services over a wireless network by dynamically controlling a broadcast rate, comprising: suppressing an automatic rate fallback protocol so that a broadcast data rate is not limited to the base data rate; transmitting a multicast data stream from an access point to a plurality of nodes; detecting if there is any data loss in the said multicast data stream; and lowering the data rate for each node incrementally if there is any data loss, until the data loss reaches an acceptable level or until the said minimum rate is reached, whichever happens first.

Abstract:
A system (10) for power management with optimized connectivity in handoff of mobile device (11) between heterogeneous network (12, 13, 14) said mobile device (11) comprising a power management module which obtains power state information of said mobile device (11), and a network interface management module which includes a prioritized set of network interfaces (12, 13, 14) to enable said mobile device (11) to select for optimum quality of connection according to the power state of said mobile device (11).
Abstract:
The present invention provides a method for providing a direct communication between a 6LoWPAN communicator and 6LoWPAN sensor nodes. The method includes data requesting and forwarding algorithms in 6LoWPAN which send packets from a sensor node directly to the 6LoWPAN communicator in a single hop without using routing mechanism.
