A secure authentication protocol for IP-based wireless sensor communications using the location/ID split protocol (LISP)

The future of the Internet of Things (IoT) involves a huge number of node devices such as wireless sensors that can communicate in a machine-to-machine pattern, where devices will be globally addressed and identified. As the number of connected devices increased, the burden on the network infrastructure and the size of the routing tables and the efficiency of the current routing protocols in the Internet backbone increased as well. Recently, an IETF working group, along with the research group at Cisco, are working on a Locator/ID Separation Protocol as a routing architecture that provides new semantics for IP addressing, in order to simplify routing operations and improve scalability in the future of the Internet such as the IoT. In the light of the previous issue; this paper proposes an efficient security authentication and a key exchange scheme that is suited for Internet of things based on Locator/ID Separation protocol. The proposed protocol method meets practicability, simplicity, and strong notions of security. The protocol is verified using Automated Validation Internet Security Protocols and Applications (AVISPA) which is a push button tool for the automated validation of security protocols and the achieved results showed that they do not have any security flaws

Performance evaluation of LTE network via using fixed/mobile femtocells

This paper examines the concept of Mobile Femtocells to be the revolution of the next generation cellular networks. Mobile Femtocells can be deployed in public transportation vehicles such as trains, buses or private cars that form its own cell inside vehicles to serve vehicular and mobile User Equipments. The purpose of this study is to help cell-edge users to have better signal strength. Therefore, an investigation into Long Term Evolution cell-edge users' performance is being conducted by investigating the deployment of Mobile Femtocells in LTE system. The throughput for cell edge users can be improved by deploying Fixed/Mobile Femtocells. In this paper, two scenarios have been considered in the case of Fixed/Mobile Femtocells. The handover of Mobile Femtocell has been expressed in three more scenarios. The achieved results via Matlab simulation showed that Mobile Femtocells' users have enjoyed better Quality of Services than Fixed Femtocells' users. The improved performance has been noticed through the improvement of the Mobile Femtocells UEs' spectral efficiency, throughput and SINR over the Fixed Femtocells' users. The system behavior has been investigated under low, medium and high load traffic before and after adding the Mobile Femtocells. The results showed that adding the Mobile Femtocells in the high loaded traffic areas has the biggest affect on improving the UE's throughput

A Survey on Authentication and Key Agreement Protocols in Heterogeneous Networks

Unlike current closed systems such as 2nd and 3rd generations where the core network is controlled by a sole network operator, multiple network operators will coexist and manage the core network in Next Generation Networks (NGNs). This open architecture and the collaboration between different network operators will support ubiquitous connectivity and thus enhances users' experience. However, this brings to the fore certain security issues which must be addressed, the most important of which is the initial Authentication and Key Agreement (AKA) to identify and authorize mobile nodes on these various networks. This paper looks at how existing research efforts the HOKEY WG, Mobile Ethernet and 3GPP frameworks respond to this new environment and provide security mechanisms. The analysis shows that most of the research had realized the openness of the core network and tried to deal with it using different methods. These methods will be extensively analysed in order to highlight their strengths and weaknesses

Performance evaluation of mobile users served by fixed and mobile femtocells in LTE networks

This paper investigates the concept of Mobile Femtocell with considering the feasibility of deploying Mobile Femtocells in public transportation vehicles such as trains, buses or private cars that form its own cell inside vehicles to serve vehicular and mobile User Equipments. This study is the launch of cell-edge mobile users who have always suffered degradation in the Quality of Service (QoS). Therefore, an investigation on the performance of LTE cell-edge mobile User Equipment e.g. users’ throughput, SINR, SNR, SIR, spectral efficiency and Handover performance, have been considered with deploying Fixed Femtocells and Mobile Femtocells in Long Term Evolution network. Two scenarios have been proposed in this study; Fixed Femtocells with mobile users and Mobile Femtocells with mobile users. More scenarios maybe considered in the case of Mobile Femtocell’s handover procedure. MATLAB simulation has been used for the purpose of simulating the designed scenarios and implementing the integrated mathematical equations. The simulated results have demonstrated the benefits of having Mobile Femtocells over the Fixed Femtocells in terms of mobile User Equipments’ performance

Interference management for co-channel mobile femtocells technology in LTE networks

The dense deployment of Femtocells within the Macrocell's coverage is expected to dominate the future of Long Term Evolution (LTE) networks. While Mobile Femtocells (Mobile-Femtos) could be the solution for vehicular networks when there is a need to improve the vehicular User Equipment (UE) performance by mitigating the impact of penetration loss and path-loss issues. The deployed Femtocells have operated in a co-channel deployment due to the scarcity of spectrums. This issue causes interference between Femtocells and Macrocells as well it causes extra overhead on the LTE networks because of the co-tire interference between adjacent Femtocells. In this paper two interference scenarios are considered, the interference between Mobile-Femto and Macrocell, and the interference between the Mobile Femtos themselves. Therefore, to avoid the generated interference between Femtocells, the controlled transmission powers as well as the coverage planning techniques have been discussed. While in the worst-case scenarios, a frequency reuse scheme has been proposed to avoid the generated interference effectively and dynamically between the Mobile-Femtos as well as their UEs and between the Macrocell UEs
