IP Mobility in Aeronautical Communications

International audienceIn the sake of modernization, aviation stakeholders decided that the future aviation network infrastructure, in particular for air-ground communication systems, will move towards IP based networks. It has been referred to in the International Civil Aviation Organization as Aeronautical Telecommunication Network/Internet Protocol Suite. Due to the heterogeneous communication environment , it is necessary to support handover between different access technologies and access networks. In this article, we first define the very specific aeronautical communication environment. Our main contribution is a performance assessment of the most deployed network protocols capable of managing IP mobility within the aeronautical environment. We focus our analysis on the Mobile IPv6 protocol and implementation issues of a representative aeronautical network in Omnet++

Enhancement of FMIPv6 by Utilising Concurent Binding Update Process

The world is progressing toward the Mobile Internet Protocol Television (MIPTV) era where people are able to watch television while roaming. The MIPTV technology requires high bandwidth and low latency handover. This paper enhances the binding updates process in the Fast Handover Mobile IPv6 (FMIPv6) to improve its handover process performance in term of secureness and robustness, by implementing concurant binding update process thru the use of the International Mobile Subscriber Identifier (IMSI). Simulation results show that the proposed idea reduces the handover latency to about 63% compared to standard FMIPv6

IMSI-based care of-address creation for fast binding update in MIPv6

The growth of Internet user forced the fixed line Internet user to migrate from IPv4 to IPv6 due to the address availability.The similar situation will arise in mobile Internet, in which will forced the users to migrate to IPv6-based network.The numbers of Internet user also affect the access router work load and may grounds the latency in data reception.Handover from one access router to another needs a mechanism called binding update which produces latency.The most liable process in this mechanism is Duplicate Address Detection (DAD) in which take longer time than any other process.This paper proposes a mechanism to reduce the handover latency by eliminating the DAD process, using IMSI number

Advanced mobility handover for mobile IPv6 based wireless networks

We propose an Advanced Mobility Handover scheme (AMH) in this paper for seamless mobility in MIPv6-based wireless networks. In the proposed scheme, the mobile node utilizes a unique home IPv6 address developed to maintain communication with other corresponding nodes without a care-of-address during the roaming process. The IPv6 address for each MN during the first round of AMH process is uniquely identified by HA using the developed MN-ID field as a global permanent, which is identifying uniquely the IPv6 address of MN. Moreover, a temporary MN-ID is generated by access point each time an MN is associated with a particular AP and temporarily saved in a developed table inside the AP. When employing the AMH scheme, the handover process in the network layer is performed prior to its default time. That is, the mobility handover process in the network layer is tackled by a trigger developed AMH message to the next access point. Thus, a mobile node keeps communicating with the current access point while the network layer handover is executed by the next access point. The mathematical analyses and simulation results show that the proposed scheme performs better as compared with the existing approaches.Sadiq, AS.; Fisal, NB.; Ghafoor, KZ.; Lloret, J. (2014).

Implementation and Analysis of FMIPv6, an Enhancement of MIPv6

International audienceThe initial IP Mobility protocol was rst presented in 1993 for IPv4. The Mobile IP protocol solves the TCP/IP Layer 3 mobility, by assigning a permanent IP address to the mobile node. Mobile IP consists of both MIPv4 and MIPv6, but IPv4 has a couple of drawbacks, the main one being IP address exhaustion, making MIPv6 the future option for mobility protocol in IP Networks.The main goal of the mobility protocol is to enable network applications to operate continuously at the required quality of service for both wired and wireless networks. MIPv6 uses the existing IPv6 protocol to enable seamless roaming between di erent ac- cess points. MIPv6 on its own needs optimization techniques to improve the handover latency of the protocol and to minimize the latency. This paper proposes FMIPv6 protocol to minimize handover latency. Both MIPv6 and FMIPv6 protocols introduce some new terminologies as pro- posed by the Internet Engineering Task Force (IETF), which require prior familiarisation to understand the working of MIPv6 and FMIPv6

Reliable Communication in Wireless Networks

Wireless communication systems are increasingly being used in industries and infrastructures since they offer significant advantages such as cost effectiveness and scalability with respect to wired communication system. However, the broadcast feature and the unreliable links in the wireless communication system may cause more communication collisions and redundant transmissions. Consequently, guaranteeing reliable and efficient transmission in wireless communication systems has become a big challenging issue. In particular, analysis and evaluation of reliable transmission protocols in wireless sensor networks (WSNs) and radio frequency identification system (RFID) are strongly required. This thesis proposes to model, analyze and evaluate self-configuration algorithms in wireless communication systems. The objective is to propose innovative solutions for communication protocols in WSNs and RFID systems, aiming at optimizing the performance of the algorithms in terms of throughput, reliability and power consumption. The first activity focuses on communication protocols in WSNs, which have been investigated, evaluated and optimized, in order to ensure fast and reliable data transmission between sensor nodes. The second research topic addresses the interference problem in RFID systems. The target is to evaluate and develop precise models for accurately describing the interference among readers. Based on these models, new solutions for reducing collision in RFID systems have been investigated
