At present, many studies focus on the efficiency of handoff among different networks, while research on how to maintain the safety during registration process of handoff is not enough. Unfortunately, mobile node is vulnerable to various security threats and attacks when handover for being lack of protection. A security scheme based on the IPSec protocol which was combined with fast handoff signaling...
In the IPv4 wireless network, the quality of the communications between the wearable computers or the mobile nodes is slow and the wearable computers cannot achieve in the sub-seamless switching between LANs. According to the three function entities of mobile IPv6 the protocol stack software is divided into three major modules, and proposed design program and the division of sub-module based on the...
The signals in the e-health support and curing system should be transferred in high quality, but in the traditional wireless network, the quality and the speed of the communications between the mobile e-health computers is slow. According to the three function entities of mobile IPv6 the protocol stack software is divided into several major modules, and proposed design and the division of sub-module...

Traditional wearable systems cannot communicate the location with the condition of people instantly, dynamically and accurately and it is also in low-speed, high-latency and unreliable; the system configuration information with location needs to be changed frequently. By emulating a distributed arithmetic, it analyzes the load of the communication network, the average time that the mobile agent has...
The wearable video system supports decision making through analyzing video images. Because personnel who wear the system or the object monitored is always moving, the technology of motion detection and target contour extraction used in the wearable video system are studied. First, the frequently-used algorithms for motion detection are studied, including frame difference method and background subtraction...
Mobile IP encapsulation mechanism is used for mobile nodes and communication nodes to communicate. Communication of Mobile nodes and communication nodes have two possible ways. The first method is a two-way tunnel mode. Another way is to use route optimization. Two-way tunnel mode is not require the another communication end to support mobile IP. When the mobile node not to register to the other communicate...
The key technology of Next generation distance education mobile platforms is the mobile IPv6 protocol implementation technology in real time embedded operating system environment on handheld hardware platform. This paper the main design goal standards is to IETF's RFC document as the basis to establish the basic framework for mobile IP,for the existing protocol stack to provide mobility support. The...
