A Simplified Protocol Stack for Improved IOT Support in LTE

With the increased usage of number of devices using Internet of Things (IoT) it is imperative for IoT devices to be connected to an architecture that provides seamless integration of services from one to another end. THE LONG-TERM evolution-LTE systems becomes the best partner to match the service requirements of the same. In this paper, we present a novel protocol architecture, namely, Reduced Control Plane Protocol(RRCP) architecture suite to effectively reduce the number of signaling messages or reduce the duplication of signaling messages when an User Equipment (UE) tries to join the LTE network from its sleep mode. We evaluate the performance of the proposed scheme with conventional scheme in terms of many metrics which include, number of channels allocated, delay and energy consumed and prove that the proposed architecture is much better than the existing conventional architecture.

EAPSG: Efficient authentication protocol for secure group communications in maritime wideband communication networks

The maritime wideband communication network, which extends the operation of wireless access from land to sea, will significantly contribute to the maritime distress, urgency, safety, and general communications. The Worldwide Interoperability for Microwave Access (WiMAX) technology has been applied to establish a maritime wideband shore-side network infrastructure, to achieve large capacity data backhauls. However, in this scenario, many new security and privacy challenges are arising, e.g., the reduced time overhead for group access authentication due to limited time window vessels passing by infostations along the shore-side. In this paper, a simple and reliable group authentication framework is developed for dealing with security issues in this special maritime wideband communication scenario. Specifically, an efficient authentication protocol for secure group communications (EAPSG) in maritime wideband communication network is proposed based on the Elliptic Curve Diffie-Hellman (ECDH), to overcome the weakness existing in the prevailing protocols on land, i.e., user identity disclosure, the lack of perfect forward secrecy, and man-in-the-middle attacks. Meanwhile, EAPSG can reduce the communication overhead and computational complexity by designing group access authentication procedures. Compared with conventional EAP-AKA protocol used in WiMAX networks on land, our scheme enhances the security and provides better performance. Especially, the security of the proposed protocol was verified by Automated Validation of Internet Security Protocols and Applications (AVISPA), and detailed performance evaluations are also given. The results illustrate that the proposed EAPSG outperforms other existing schemes on land in terms of the delivery cost and the number of signaling messages.

A novel group access authentication and key agreement protocol for machine‐type communication

AbstractMachine‐to‐machine communications have been actively engaged in by the standardisation and industry areas, also defined as machine‐type communication (MTC) in the release 10 of the 3rd Generation Partnership Project. The scenarios of 3rd Generation Partnership Project have been regarded as the promising solution facilitating machine‐to‐machine communications, which is being standardised as an emphatic application to be supported by long‐term evolution advanced. In this paper, we propose a novel group access authentication and key agreement protocol for MTC devices, which effectively reduces authentication costs compared with conventional schemes. In our proposed protocol, the first MTC device accessing the network performs a full authentication and key agreement authentication procedure and obtains a group temporary key and group authentication information on behalf of other MTC devices in the same group; then, the remaining MTC devices perform a simplified authentication procedure locally. The key derivation and group member joining and leaving are also discussed. Finally, the security of the proposed protocol is verified by using the AVISPA toolkit, and extensive evaluations of performance illustrate that the proposed protocol achieves better performance in terms of the bandwidth consumption, the number of signaling messages between the home network and the serving network, the computation cost and the storage cost in the serving network compared with several existing schemes.

Reactive Handover Optimization in IPv6-Based Mobile Networks

In recent years, there has been a rapid growth in the need to support moving hosts and moving networks in IPv6-based mobile networks. As the number of such hosts and networks grows, so will the demand for delay sensitive real-time applications, such as voice over IP (VoIP), that require seamless handover. Two well-known approaches to reduce the handover latency have been proposed in the literature: proactive and reactive approaches. While proactive handover is known to generally outperform reactive handover, its reliability and practicality are still questionable since it basically depends on predictive information which may be unreliable in some cases. In this paper, based on the standard specification for IPv6 mobility support, we analyze the existing movement detection and address configuration procedures which are the main components of reactive handover approach. We also propose a novel reactive handover procedure which employs our optimized movement detection and address configuration schemes. The proposal is simple and robust because it does not need any predictive information and it requires a minimum number of signaling messages. The performance evaluation shows that the proposal substantially reduces the signaling load on wireless/wired networks and its handover latency is reduced enough to support seamless services

Dynamic Aggregation of Reservations for Internet Services

Global availability of on-demand services with an associated guaranteed quality-of-service (QoS) is still missing in the Internet today. The Differentiated Services architecture achieves scalability in the data plane by treating all flows with a specific type of service as one aggregate. In order to provide guaranteed end-to-end reservations, the control plane (e.g., performing admission control and management of resource reservations) has to be scalable as well. The DARIS architecture provides this essential linkage between scalability in the packet forwarding path and scalability of QoS management in the Internet. It comprises a novel concept of dynamic and hierarchical aggregation, which acts on the network level of autonomous systems (ASes). This relieves management entities in intermediate ASes of processing load by reducing their managed reservation states as well as the number of signaling messages that have to be processed significantly. Moreover, novel and special support for aggregation by a dedicated signaling protocol mechanism is provided.

Performance analysis of two schemes for managing information related to incall registration in wireline UPT networks

In universal personal telecommunication (UPT) environments, UPT networks retain information related to incall registration in UPT user service profiles in order to provide incoming UPT calls for UPT users at any terminal in any location. As UPT networks support incall registration, terminal users can be different from terminal owners, and several UPT users can register on a single terminal for their incoming calls. Therefore, appropriate third-party protection procedures are needed to protect the rights of terminal owners from UPT users. A database called the terminal profile is needed to store the information of the terminal states and the incall UPT users registered on the terminal in order to carry out third-party protection procedures. In order to manage information within the terminal profile and the service profile, this article proposes two schemes, a request-based scheme and a timer-based scheme. The performance of the two schemes is compared in terms of the number of signaling messages transferred between a service switching point (SSP) and a service control point (SCP) per incall registration reset for a terminal.
