It cannot satisfy higher levels of security requirements of the space network that just implement protection in only one protocol layer. But, most space mission cannot simultaneously carry on the security in the multiple layers, because of that is easy to have the repetition induction, and introduce shortage of security, and increase development and the operating cost. In this paper, we proposed the...
A dynamic policy based network management scheme is presented for the problem that traditional policies can??t preferably adapt to change of network state. It defined dynamic policy form and appended new module PMA to IETF policy frame to improves the adaptability of policie. Then the application of dynamic policy to allocate resource is presented. By experiment and analysis, it is shown that this...
Concept lattice was creatively used in mining correlated policy rules in this study. It takes much time for a conflict detection routine to search every policy in policy repository with conventional policy storage models to see if conflict occurs before a new dynamic policy is added to the policy repository. A novel storage model for dynamic policies was proposed to address this problem. Dynamic policies...
Current mobile network architecture is constructed through introducing mobile IP protocol on the basis of IP network. On the one hand it cannot break away from the inherent limitation of IP network, such as no strong security, complex forwarding devices, lack of high expansibility and no QoS guarantee. On the other hand it brings some new problems due to the repair to IP network, such as the triangular...
The platform of quick development of mobile 3D game can be used to reduce the mobile 3d phone games' develop-cycle. With this platform, the developers can break out of the complexity of programming. Thus more efforts will be putted into enriching contents of the game itself. The core of the platform of quick development of mobile 3D game is the ability of configuration, which can be divided into the...
This paper presents the patterns about shifting a computer game to a physical game which is usually the pervasive and social computing based on wireless sensor networks (WSN), RFID, GPS and other mobile devices. These shift patterns, focused on the aspects that most computer games highlight and guidelines for transforming these aspects into physical forms, help people design and implement new physical...
Mobile E-commerce (M-commerce) service raises a number of security and privacy challenges. To address this, we propose an advanced mobile security solution and related security methodology based on distribute key without changing hardware configuration of the mobile devices. The solution consists of the UE (User Equipment), an electronic security key (eKey) which is connected to the mobile device...
In the fields of deployments in wireless sensor networks, the method of stationary sensor nodes deployed in the area has already been done extensively. However, in a multilayer wireless sensor network, the deployment and movement control strategy for mobile nodes was done little. To guarantee the reliability of the data transmission, this paper proposes a virtual grid partition deployment method,...
