Abstract:
The Cloud network architecture having a mesh configuration includes at least one of Cloud base station (BS) and Master Cloud Arbitrator (M-CA) (200) or Cell Site Cloud Arbitrator (CS-CA) (300) and Backhaul Points (BP) (400). The Cloud base station (BS and M-CA/CS-CA) employs an intelligent decision engine for calculating the most efficient route and assigning the best possible resources available. The Cloud network of the present invention comprises of Backhaul Points (400) to provide a scalable and resilient communication link while maintaining the quality of service (QoS) to the neighboring M-CA/CS-CA/BP (200, 300, 400). The Backhaul Points (400) of the present invention also uses sensors (212, 312, 408) to send data to Cloud base stations for decision-making.
Abstract:
The present invention relates to a method to allow multiple virtual local area network (VLAN) traffics to traverse over a wireless multi-hop network. The method is characterised by the steps of performing initialization phase, wherein the initialization phase includes exchanging media access control (MAC) addresses and Basic Service Set Identifications (BSSIDs) information between an access point (AP) (200) and a relay client (300); performing AP (200) to relay client (300) operation phase, wherein the AP (200) to relay client (300) operation phase includes transmitting a modified MAC address from AP (200) to the relay client (300); and performing relay client (300) to AP (200) operation phase, wherein the relay client (300) to AP (200) operation phase includes transmitting a modified transmitter MAC address at the packet header from relay client (300) to AP (200).
Abstract:
The present invention discloses a method for prioritizing channel access in a wireless communication network. The method comprising registering with an access point (102) by one or more station as priority stations (101) during a Contention Period established by the access point (102) operating in the Distributed Coordination Function. The registered priority stations (101) will trigger the access point (102) to switch from the Distributed Coordination Function to the Point Coordination Function and thereby establishing a Contention Free Period when there is urgency by these priority stations (101) to access a channel. During the Contention Free Period, the access point (102) will first poll the registered priority stations (101) with higher priority level and grant them the priority to access the channel than those priority stations (101) with lower priority level. The access point (102) will resume the Coordination Period when the maximum Contention-Free-Period duration is reached and/or all the registered priority stations (101) have transmitted.
Abstract:
A method for automated cluster head mechanism in multicast communication over a multi-cluster wireless network, comprising designating, by an Enterprise Gateway, a best ranking client from a plurality of clients in a cluster of the multi-cluster wireless network, as a Cluster Head (102), announcing the Cluster Head, by the Enterprise Gateway, to the plurality of clients in the cluster (104) and assigning to the cluster, by the Enterprise Gateway, subscription of new clients of the multi-cluster wireless network (106). The method further comprising notifying, by the Cluster Head to the Enterprise Gateway once a maximum capacity is achieved (108) and receiving, by the Enterprise Gateway direct subscription of new client of the multi-cluster wireless network (110).
Abstract:
The present invention relates to a system and method for propagating VLAN traffic over a wireless multi-hop network. The system (100) comprises of a physical ingress module (110), two labeller modules (120), two splitter modules (130), at least one virtual ingress module (140), at least one virtual egress module (150), a physical egress module (160), a virtual backhaul module (170), an interface virtualization module (180), and at least one dummy virtual module (190). The system (100) duplicates data packets received to transmit the data packet to the other systems (100) in the following hop.
Abstract:
The present invention relates to a method of selecting an access gateway from a plurality of detected gateways in a mobile node, in particular in mobile IP. The mobile node is provided with more than one gateway to access a telecommunication network. The mobile node carries several egress interfaces and each of these interfaces is capable of connecting the mobile node to the home agent as long the correct gateway is presented. In the prior art, the mobile node only binds to a specific gateway selected by or assigned to the user without considering other gateway made available for binding. This might lead to crowding a single gateway and competing for the limited bandwidth while leaving other available gateways idle is waste of network resources. This problem is overcome by the application in that the mobile node dynamically selects (106) and binds ((107) to the best gate¬ way which is the gateway with the highest priority score. The priority score is computed (105) for each gateway from a first value (102) generated for each gateway according to decay history, DH, a second value (103) generated for each gateway according to round trip time, RTT, of the gateway and a third value (104) generated for each gateway from pre-set priority, PP, data. The round trip time is preferably measured by sending ICMP packets through the available gateways (302).
Abstract:
Global services redundancy is provided using IP address mobility wherein the main server obtains an address which is the same address registered in the DNS server which allows clients access services offered by the server through the assigned IP in the DNS. Redundant server is required to be in the same LAN as the main server and if the link to both the servers fails, then the service is disrupted. The present invention introduces a Session Capturing Server (SCS) the Session Capturing Server (SCS) to maintain mapping table of redundant servers IP address with main servers IP address. Session Capturing Server (SCS) captures ongoing sessions of the main server that has failed and forward the captured sessions to a backup server for continuing services.
