Abstract: THE PRESENT INVENTION RELATES TO A METHOD FOR USE IN A HAND-OFF PROCESS BETWEEN BASE STATIONS, PREFERABLY WIFI/WiMAX BASE STATIONS. THE PRIMARY STEPS INCLUDE ARRANGING THE SUBNET FOR EACH BASE STATION IN A PREDETERMINED SEQUENCE AND THUS PREDICTING THE MOST POSSIBLE SUBNET PREFIX OF THE NETWORK THAT A NODE WOULD ATTACH NEXT (S300). BY WAY OF PREDICTING THE SECONDARY AND TERTIARY ADDRESS (S500), THE CARE-OF ADDRESS OF THE BASE STATION IS OBTAINED. A PING PACKET IS FURTHER SENT TO THE NEXT BASE STATION'S IP ADDRESS WITH THE SECONDARY ADDRESS AND THE PREVIOUS BASE STATION IP ADDRESS WITH THE TERTIARY ADDRESS (S400) TO OBTAIN A CARE-OF-ADDRESS.

Abstract: THE PRESENT INVENTION RELATES TO A METHOD FOR RE-CONNECTING AN ISOLATED NODE IN A WIRELESS MESH NETWORK. WHEN A NODE IS ISOLATED FROM ITS NETWORK, THE METHOD ALLOWS THE NODE TO RE-CONNECT TO ITS NETWORK BY ROUTING THE ISOLATED NODE THROUGH A NEIGHBOURING WIRELESS MESH NETWORK. EACH NETWORK COMPRISES OF A GATEWAY (50) AND A PLURALITY OF WIRELESS NODES. THE GATEWAY (50) INCLUDES A MEMORY (51), AND A PROCESSOR (52) HAVING A COLLABORATION MODULE (53) AND A TRUST MODULE (54). THE COLLABORATION MODULE (53) IS USED TO ALLOW COLLABORATION BETWEEN THE WIRELESS MESH NETWORK AND THE NEIGHBOURING NETWORK. THE TRUST MODULE (54) IS USED TO DETERMINE WHETHER THE ISOLATED NODE BELONGS TO THE WIRELESS MESH NETWORK. EACH WIRELESS NODE (10) INCLUDES A MEMORY (11), AND A PROCESSOR (12) HAVING A COLLABORATION MODULE (13) TO ALLOW COMMUNICATION BETWEEN THE NODE (10) AND A WIRELESS NODE (10) OF THE NEIGHBOURING NETWORK.

Abstract: THE PRESENT INVENTION RELATES TO AN ENHANCED METHOD OF STREAMING MULTICAST TRAFFIC USING ENTERPRISE GATEWAY. THE ENTERPRISE GATEWAY (30) DESIGNATES CLUSTER HEADS (10), (13) FOR EACH MULTICAST CLUSTER. EACH CLUSTER HEAD (10), (13) IS RESPONSIBLE FOR DELIVERING THE RECEIVED TRAFFIC FROM THE ENTERPRISE GATEWAY (30) TO ALL MULTICAST SUBSCRIBERS IN ITS CLUSTER BY MAPPING THE TRAFFIC TO THE CLUSTER SUBSCRIBERS' UNICAST MAC ADDRESS. THE NUMBER OF CHOSEN CLUSTER HEADS ARE LIMITED; TO AVOID ANY UNNECESSARY INTERFERENCE AMONG THESE CLUSTER HEADS. THOSE SUBSCRIBERS WITHOUT VIRTUAL ACCESS POINT (VAP) CAPABILITIES, OR THE NUMBER OF CLUSTER HEADS REACHES THE MAXIMUM LIMIT, THEREFORE THE SUBSCRIBERS CAN JOIN THE ENTERPRISE GATEWAY (30), AND THEN THE ENTERPRISE GATEWAY (30) STREAMS DIRECT TO THEM USING THEIR MAC ADDRESS.
