Route optimization scenario of a new scheme based on nested mobile network

With the rapid growth of wireless technologies and increasing number of mobile digital devices, mobility has been an important element on the Internet. NEMO Basic Support, designed by the Internet Engineering Task Force (IETF) to provide network mobility, is not efficient to offer low latency handoff in the case of nested mobile networks because it produces a long transfer delay and excessively large packet sizes due to non-optimal routes and multiple encapsulations. This paper presents a route optimization scenario for nested mobile network using hierarchical structure with Binding Update Tree (BUT). This scheme should reduce packet overhead, handoff latency, packet transmission delay, and achieve optimal routing.

Analysis of Wardriving Activity and WiFi Access Points

This paper proposes a system composed of hardware and software components that facilitates the activity of wardriving and assists in collecting statistical data by GPS of WiFi networks and their security status in particular area. The application has the potential of being used as a tool to study WiFi security trends or for misuse and WiFi exploitation.

Dynamic batch rekeying scheme using Multiple Logical key trees for secure multicast communication

A group key management has an important role in multicast security in order to achieve data integrity and confidentiality. The session key is a common secret key for a group of users in key trees that is shared securely and efficiently among them. It is used to encrypt other session keys and transmitted data in order to protect group communication. This paper proposed a new key management protocol using Multiple Logical key trees for dynamic groups. To minimize the communication overhead of rekeying process, a one-way key derivation are integrated with multiple logical key trees. New keys created by the server of the key tree are not sent to the members who are able to derive their own keys. As a result each rekeying process requires less number of encrypted keys sent within the group tree. The performance analysis of the proposed scheme shows that it has less communication cost than the other compared protocols.

A framework of a route optimization scheme for nested mobile network

Network mobility technology is now being accomplished with the foundation of NEMO (NEtwork MObility), developed by Internet Engineering Task Force (IETF). Although, it achieves optimal and continuous communication, it still suffers from some limitations, especially when the level of nesting increases. To overcome these drawbacks, this paper will present a route optimization framework for nested mobile network using hierarchical structure with Binding Update Tree (BUT). This framework should reduce packet overhead, handoff latency, packet transmission delay, and achieve optimal routing. At last, a comparison will be done with bi-directional tunneling used by NEMO Basic Support to evaluate the performance of the proposed framework.
