Abstract: THE PRESENT INVENTION PROVIDES A METHOD AND SYSTEM FOR HANDOFF CONTROL IN A WIRELESS COMMUNICATION NETWORK. IN AN EMBODIMENT, A METHOD FOR HANDOFF CONTROL IN AN IP BASED WIRELESS COMMUNICATION NETWORK, COMPRISING (I) MONITORING AND OBTAINING MOVEMENT INFORMATION OF A MOVING MOBILE NODE (10), (II) PREDICTING THE NEXT POINT OF NETWORK ATTACHMENT FOR THE CLIENT MOBILE NODE (10), AND (III) PERFORMING THE HANDOFF OPERATION BEFORE THE MOBILE NODE (10) MOVES TO A NEW LOCATION CORRESPONDING TO NEXT POINT OF NETWORK ATTACHMENT, WHEREIN THE INTERRUPTION TIME DURING THE HANDOFF IS SUBSTANTIALLY MINIMUM.

Abstract: THE PROPOSED HANDOVER SCHEME ACCORDING TO THE PRESENT INVENTION IS AN ENHANCEMENT OF THE EXISTING MOBILE IPV6 PROTOCOL; IT INTEGRATES HIERARCHICAL CONCEPT AND MULTICAST FUNCTION. HIERARCHICAL DESIGN WAS USED TO SHIELD THE MICRO MOBILITY FROM MACRO MOBILITY IN ORDER TO REDUCE LOCATION UPDATE SIGNAL AND SIGNALING TRAFFIC WITHIN MICRO LEVEL NETWORK WHILE MULTICASTING IS USED TO SEND PACKETS TO MOBILE NODE (6) THROUGH BASE STATIONS (4,5) THAT ARE NEAR TO MOBILE NODE (6). THIS WILL REDUCE HANDOVER DELAY THAT CAUSES PACKET LOST WHEN MOBILE NODE (6) IS ROAMING. THE PROPOSED SECURITY SCHEME IS AN EXTENDED ENHANCEMENT OF THE EXISTING MOBILE IPV6 SECURITY PROTOCOL. IT CAN DETECT MAN-IN-THE-MIDDLE ATTACKS OR ATTACKS AGAINST DATA AND THEN PREVENT THEM. EACH MOBILE NODE CAN TRUST ITSELF TO CHECK WHETHER THE CONNECTION IS SECURED OR NOT. IT IS DONE BY REQUESTING THE RECEIVER OR SERVER TO RETURN SOME SELECTED PACKET TO COMPARE WITH THE ORIGINAL GENERATED. IN THIS METHOD, IT IS PROPOSED TO USE ENCRYPTION IF ANY ATTACK IS DETECTED SO IS NOT INCREASE THE DELAY. (THE MOST ILLUSTRATIVE

Abstract: The present invention a method for encapsulating multicast packets (1) in unicast packets (2), the method comprising of; a) working in parallel at least two servers (5), a web server (51) and a streaming server (52); b) sending out a web page (30) by the web server (51) and streaming a multimedia file (40) by the streaming server (52) directly to at least one viewer (20); c) streaming multicast packets (1) by the streaming server (52) and sending unicast packets (2) by the web server (51) but displayed as a single web page in at least one viewer (20) web browser (400); d) eliminating the needs of sending multimedia file (40) by the web server (51) to make it possible for a multicast multimedia file (40) to be streamed to the at least one viewer (20).

Abstract translation: 本发明是一种在单播分组（2）中封装多播分组（1）的方法，该方法包括： a）并行工作至少两个服务器（5），web服务器（51）和流服务器（52）; b）由web服务器（51）发送一个网页（30），并将该流媒体服务器（52）的多媒体文件（40）直接传送到至少一个观看者（20）; c）由流服务器（52）流式传输多播数据包（1），并由web服务器（51）发送单播数据包（2），但在至少一个浏览器（20）网络浏览器（400）中显示为单个网页; d）消除由web服务器（51）发送多媒体文件（40）的需要，使多播多媒体文件（40）能够被传输到至少一个观看者（20）。
