Abstract:
The present invention relates to a method for surrogate monitoring on-air-information of a plurality of radio access points that are co-located by using an independent monitoring radio. In general, the monitoring radio performs scanning or monitoring of on-the-air information, specifically time variant parameters and time invariant parameters, specified by and on behalf of the radio access points in order to significantly free the resources required by the said radio access points to perform their normal operation. According to the present invention, the radio access points must be within the scanning vicinity of the monitoring radio and registered with a central manager, which can be determined by the step of radio access points discovery (210). Further, the present invention introduces steps of scan or monitor capability matching (220), synchronization (230), and qualification (240) to select, determine, and register the time variant parameters and time invariant parameters in a surrogate monitoring list, which is to be used by the monitoring radio as a reference to perform the scan or monitor task.

Abstract:
Load balancing of an access point (AP) in wireless networks is achieved through virtual cell sizing. The system comprising at least one wireless interface (210) adapted to associate and communicate with wireless users; at least one AP interface (230) adapted to communicate with neighbouring APs; at least one scanning interface (220) adapted to detect user stations (STAs) associated with said AP; at least one STAs detection module (SOM) (240) in communication with said at least one scanning interface (220) and said at least one AP interface (230), said SOM (240) being adapted to detect target STAs for potential offloading and communicate with SDMs of neighbouring APs; at least one AP loading monitor and decision module (ALOM) (250) in communication with said SOM (240) and said at least one wireless interface (210), said ALDM (250) being adapted to monitor the level of loading of said AP; at least one support rates controller (SRC) (260) in communication with said ALDM (250), said SRC (260) being adapted to control supported rates of said AP; and at least one beacon updater (BU) (280) in communication with said SRC (260), said BU (280) being adapted to update a support rates field in a beacon broadcast by said AP. The AP loading monitor and decision module (ALDM) (250) monitors the load of said AP and is adapted to determine whether to off- load excessive STAs to neighbouring APs by shutting down a supported rate, or to enable a supported rate when said AP is underloaded.
Abstract:
The present invention relates to a system (100) for allocating bandwidth in a wireless multi-hop network. The system (100) provides fair bandwidth sharing among all nodes in the wireless multi-hop network. Generally, the system (100) comprises of a gateway (110) and a plurality of nodes (120). In each node (120) and gateway (110), there is provided a resource agent (130). The resource agent (130) is used for aggregating bandwidth demand from its child nodes and allocating bandwidth to its child nodes. The resource agent (130) includes a bandwidth request module (131), a bandwidth allocation module (132), a bandwidth table (133), a bandwidth controller module (134), and a communication interface module (135).

Abstract:
THE PRESENT INVENTION RELATES TO METHOD AND SYSTEM FOR TRANSMITTING AND RECEIVING DATA PACKETS IN A WIRELESS MULTI-HOP NETWORK. A GATEWAY (100) IN THE NETWORK SCHEDULES EACH ACCESS POINT (200) TO OPERATE IN USER MODE AND RELAY MODE, WHEREIN AT ANY PERIOD OF TIME ONLY THE ACCESS POINTS (200) IN A SPECIFIC HOP OPERATE IN THE USER MODE WHILE THE ACCESS POINTS (200) IN OTHER HOPS OPERATE IN THE RELAY MODE. DURING THE USER MODE, THE ACCESS POINT (200) IS ABLE TO COMMUNICATE WITH ITS USER DEVICES (300) WHILE ONLY ABLE TO TRANSMIT TO ITS NEIGHBOURING ACCESS POINTS (200). DURING THE RELAY MODE, THE ACCESS POINT (200) IS ABLE TO COMMUNICATE WITH ITS NEIGHBOURING ACCESS POINTS (200) WHILE ONLY ABLE TO TRANSMIT TO ITS USER DEVICES (300).

Access points (110) are associated with green agent modules (120) which are adapted to monitor and manage availability of its access points (110) based on traffic load; and wireless stations (130) are associated with adaptive agent module (140) to interact with connection managers (270) for connection establishment and tear down, based on information exchanged between green agent modules (120) within said network. Green agent modules and adaptive agent modules are embedded into access points and wireless station to perform the method in achieving power saving.
Abstract:
The present invention relates to method and system for transmitting and receiving data packets in a wireless multi-hop network. A gateway (100) in the network schedules each access point (200) to operate in user mode and relay mode, wherein at any period of time only the access points (200) in a specific hop operate in the user mode while the access points (200) in other hops operate in the relay mode. During the user mode, the access point (200) is able to communicate with its user devices (300) while only able to transmit to its neighbouring access points (200). During the relay mode, the access point (200) is able to communicate with its neighbouring access points (200) while only able to transmit to its user devices (300).
