Ipv6 Mobility

Constrained application protocol (CoAP) can be used for message delivery in wireless sensor networks. Although CoAP-based proxy mobile internet protocol (PMIP) was proposed for mobility management, it resulted in handover delay and packet loss. Therefore, an enhanced PMIP version 6, with partial bicasting in CoAP-based internet of things (IoT) networks, is proposed. Here, when an IoT device moved into a new network, the corresponding mobile access gateway (MAG) updated the local mobility anchor (LMA) binding. Further, LMA initiated the “partial” bicasting of data packets to the new and the previous MAGs. The data packets were buffered at the new MAG during handover and were forwarded to Mobile Node (MN) after the handover operations. The proposed scheme was compared with the existing scheme, using ns-3 simulations. We demonstrated that the proposed scheme reduced handover delays, packet losses, end-to-end delay, throughput, and energy consumption, compared to the existing scheme.

Mobile Internet Protocol (MIP) enables a mobile node to be recognized via a single IP address while the node moves between different networks. MIP attains the connectivity to nodes everywhere without user intervention. One general improvement in Mobile IPv6 (MIPv6) compared to MIPv4 is the enhanced security. However, there are areas still susceptible to various kinds of attacks. Security approaches for the MIPv6 are still in progress and there are few unsolved concerns and problems. This chapter focuses on MIPv6 security considerations, potential threats, and possible defense mechanisms. The authors discuss and analyze in detail the MIPv6 mobility management and security approaches with respect to the efficiency and complexity and bring forward some constructive recommendations.

Mobile Access

Transmission Control Protocol (TCP), the most popular transport layer communication protocol for the Internet, was originally designed for wired networks, where bit error rate (BER) is low and congestion is the primary cause of packet loss. Since mobile access networks are prone to substantial noncongestive losses due to high BER, host motion and handoff mechanisms, they often disturb the traffic control mechanisms in TCP. So the research literature abounds in various TCP enhancements to make it survive in the mobile Internet environment, where mobile devices face temporary and unannounced loss of network connectivity when they move. Mobility of devices causes varying, increased delays and packet losses. TCP incorrectly interprets these delays and losses as sign of network congestion and invokes unnecessary control mechanisms, causing degradation in the end-to-end good put rate. This chapter provides an in-depth survey of various TCP enhancements which aim to redress the above issues and hence are specifically targeted for the mobile Internet applications.

VANET (Vehicular Ad-Hoc Network) adalah bentuk khusus dari MANET (Mobile Ad-Hoc Network). VANET (Vehicular Ad-Hoc Network) adalah jaringan yang terdiri dari kumpulan node mobile nirkabel yang berkomunikasi satu sama lain tanpa infrastruktur yang tetap. Pergerakan MN (Mobile Node) pada VANET sangat tinggi dan menyebabkan IP Address pada MN sering berubah. Berdasarkan kondisi jaringan yang berubah, koneksi yang terjadi antara MN menjadi terganggu dan terputus selama beberapa detik. Selain itu, menyebabkan delay yang besar dan throughput yang lebih kecil dengan paket loss tinggi jika di suatu daerah jumlah MN meningkat secara signifikan. Dalam simulasi ini diukur kinerja antara jaringan Mobile IPv6 (MIPv6) dan Hierarchical Mobile IPv6 (HMIPv6) menggunakan agen transport UDP dengan beberapa ukuran paket data CBR. Berdasarkan parameter utama dalam menentukan kualitas jaringan, akan dibandingkan dan diperoleh nilai dari handover latensi, dengan mengukur packet loss, throughput, dan delay. Berdasarkan hasil studi literatur, dapat disimpulkan bahwa kinerja jaringan HMIPv6 lebih baik daripada MIPv6 karena HMIPv6 memiliki paket loss dan delay yang lebih kecil dan throughput yang lebih besar dibandingkan dengan MIPv6.

<p>Mobility management protocols are very essential in the new research area of Internet of Things (IoT) as the static attributes of nodes are no longer dominant in the current environment. Proxy MIPv6 (PMIPv6) protocol is a network-based mobility management protocol, where the mobility process is relied on the network entities, named, Mobile Access Gateways (MAGs) and Local Mobility Anchor (LMA). PMIPv6 is considered as the most suitable mobility protocol for WSN as it relieves the sensor nodes from participating in the mobility signaling. However, in PMIPv6, a separate signaling is required for each mobile node (MN) registration, which may increase the network signaling overhead and lead to increase the total handoff latency. The bulk binding approaches were used to enhance the mobility signaling for MNs which are moving together from one MAG to another by exchanging a single bulk binding update message. However, in some cases there might be several MNs move at the same time but among different MAGs. In this paper, a bulk registration scheme based on the clustered sensor PMIPv6 architecture is proposed to reduce the mobility signaling cost by creating a single bulk message for all MNs attached to the cluster. Our mathematical results show that the proposed bulk scheme enhances the PMIPv6 performance by reducing the total handoff latency.</p>

Mobility Management Protocols

To provide uninterrupted communication services the IETF standardized the various communication protocols. Mobile Internet Protocol is first standard protocol and responsible for secure and reliable communication, while the mobile user switches from one geographical area to another. For such a scenario, two or more devices are permissible to exchange information, while one or more devices changing the geographical location. The implementation of mobility management protocols suffers from various challenges, such as, delay to reach data packet to its destined device, load on network, long queuing delays to data packets and it results the time out error and packet loss, reduced throughput etc. To reduce these parametric factors, concept of encryption and proxy are enabled in the proposed simulation scenarios, and new measurement to these parametric values is taken. The comparative performance needs to be measured through OPNET Modeler and results show that the proposed scheme is better than the existing one.

Mobility Management Protocols

Mobile Internet data traffic has experienced an exponential growth over the last few years due to the rise of demanding multimedia content and the increasing number of mobile devices. Seamless mobility support at the IP level is envisioned as a key architectural requirement in order to deal with the ever-increasing demand for data and to efficiently utilize a plethora of different wireless access networks. Current efforts from both industry and academia aim to evolve the mobility management protocols towards a more distributed operation to tackle shortcomings of fully centralized approaches. However, distributed solutions face several challenges that can result in lower performance which might affect real-time and multimedia applications. In this paper, we conduct an analytical and simulated evaluation of the main centralized and proposed Distributed Mobility Management (DMM) solutions. Our results show that, in some scenarios, when users move at high speed and/or when the mobile node is running long-lasting applications, the DMM approaches incur high signaling cost and long handover latency.
