Heterogeneous networks is a convergence of different wireless and mobile networks such as WiMax, 3G and LTE. These technologies need to cooperate to provide users with any time anywhere connectivity, hence the support for this heterogeneous environment is required. The wide scale deployment of such heterogeneous networks will result in a radical change in the network infrastructure, where current...
Several projects propose an information centric approach to the network of the future. Such an approach makes efficient content distribution possible by making information retrieval host-independent and integration into the network storage for caching information. Requests for particular content can, thus, be satisfied by any host or server holding a copy. One well-established approach of information...
Several research groups are working on designing new security architectures for 4G networks such as Hokey and Y-Comm. Since designing an efficient security module requires a clear identification of potential threats, this paper attempts to outline the security challenges in 4G networks. A good way to achieve this is by investigating the possibility of extending current security mechanisms to 4G networks...
Security for Next Generation Networks (NGN) is an attractive topic for many research groups. The Y-Comm security group believes that a new security approach is needed to address the security challenges in 4G networks. This paper sheds light on our approach of providing security for the Y-Comm architecture as an example of 4G communication frameworks. Our approach proposes a four-layer security integrated...
