The Next Generation Wireless Networks (NGWN) should be compatible with other communication technologies to offer the best connectivity to the mobile terminal which can access any IP based services at any time from any network without the knowledge of its user. It requires an intelligent vertical handover decision making algorithm to migrate between technologies that enable seamless mobility, al...

The essential element of the Internet Things (IoT) environment, number devices has traditionally exceeded connected to Internet. This situation is considered positive for IoT concept but still negative consequences. Undoubtedly, most prominent and important among these results security constructed environment. Group-based authentication authorization methods are crucial ensure safety many In th...

Hierarchical Mobile IPv6 introduces a new node called the Mobile Anchor Point (MAP) to improve the handover speed performance of Mobile IPv6 by reducing the amount of signaling in the ongoing connection between the mobile node, its correspondent nodes, and its home agent. With MAP as an additional node, it’s signaling, both received and sent is subject to several security vulnerabilities that n...

The deployment of mobile femtocellular networks can enhance the service quality for the users inside the vehicles. The deployment of mobile femtocells generates a lot of handover calls. Also, numbers of group handover scenarios are found in mobile femtocellular network deployment. The ability to seamlessly switch between the femtocells and the macrocell networks is a key concern for femtocell n...
