A Comprehensive Analysis of QoS in Wired and Wireless SDN Based on Mobile IP

Software-Defined Networking (SDN) is the new network paradigm whose primary focus is to create a dynamic, scalable and flexible network. It provides programmable functions for implementation of network configuration management. The demand for wireless network functionality is rising simultaneously. Mobility management for a large network is an issue in Internet Engineering Task Force (IETF). There are also a number of solutions to support mobility within the network. The Mobile Internet Protocol (MIP) is used for managing mobility. Furthermore, for the SDN platform, mobility adds roaming capability for mobile nodes in the software-defined wireless network (SDWN). In the wired scenario, SDN has different capabilities to deliver network services according to the fixed node. This study provides a quality of service (QoS) analysis in both SDN and SDWN. Mininet WiFi and RYU network emulator as a controller is used to implement the mobility API. The random walk model is applied as mobility functionality toward the final nodes. Moreover, several QoS measurement matrices are analyzed according to the network topology. At the end, round trip time (RTT), cumulative distributed function (CDF), packet loss and throughput are analyzed for quality of service comparable in the SDN and SDWN scenarios according to the MIP.

Partial Bicasting with Buffering for Proxy Mobile IPV6 Mobility Management in CoAP-Based IoT Networks

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 IPv6 Security Performance Metrics for WIMAX Roaming Environment

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.

Investigation of Internet of Things Handover Process for Information Centric Networking and Proxy Mobile Internet Protocol

IoT (Internet of Things) technically connects billions of entities to the Internet. The IoT is divided between the technology and the service itself. As a result, great efforts are needed to join data from many contexts and services. This reason has motivated proposals to develop solutions that can overcome existing issues of limitations for mobility, security, reliability and scalability of IoT. These billions of devices are interconnected to each other either using unicast, multicast or broadcast communications, and mixture of static and mobile communications. This paper aims to investigate the parameters of mobility performance in handover process for mobile multicast IoT environment. Investigation is done quantitatively by evaluating the parameters of handover process for IoT in two networking protocols that are possible to support acceptable mobility performance for IoT. The protocols are ICN (Information Centric Networking) and Proxy Mobile Internet Protocol. The evaluation parameters include packet loss and service recovery time. The metrics are extracted from the handover process flow for each network protocol topology. The service recovery time parameter is assumed as the time duration for each message to travel from sender to receiver, while packet loss parameter depends on the packet arrival rate and service recovery time. The results show that the ICN performs better than Proxy Mobile Internet Protocol.

Analisis Perbandingan Performansi MIPv6 (Mobile Internet Protocol v6) dan HMIPv6 (Hierarchical Mobile Internet Protocol v6) pada VANET (Vehicular Ad-Hoc Network)

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.

Effects of fixed and roaming CN on MIPv6 networks

Mobile Internet protocol version 6 (MIPv6) is a protocol that allows mobile nodes (MNs) to remain accessible while moving in the IPv6 network, providing users with a form of transparency in spite of the mobility. Mobile networks consist of different nodes such as the MN, correspondent node (CN), home agent (HA), foreign agent or router (FA or FR) and mobile router (MR). One of the vital nodes in a mobile network is CN, a node that communicates with the MN. In the future, in times of need, for instance, during wars, disasters or natural hazards, an MN may require the services of a CN in order to roam. In this paper, we analyse the effect of fixed and roaming CN on MIPv6 networks. The results show that, with a fixed CN, the delay variation performance, end-to-end delay and packet received are better than having a roaming CN in the mobile networks. This requires the attention of researchers, especially when all the communicating nodes (i.e., MN and CN) are roaming in the mobile networks to reduce the delay and packet drop, especially during the handover process. Keywords: MIPv6, fixed CN, roaming CN, MN, HA and FA.

APPLICATION AND SIMULATION OF ROUTE OPTIMIZATION IN MOBILE IP

Mobile Internet Protocol has been proposed by Internet Engineering Task Force (IETF) to support portable IP addresses for mobile devices that often change their network access points to the Internet. In the basic mobile IP protocol, datagrams sent from wired or wireless hosts and destined for the mobile host that is away from home, have to be routed through the home agent. Nevertheless, datagrams sent from mobile hosts to wired hosts can be routed directly. This asymmetric routing, called “triangle routing,” is often far from optimal and “route optimization” has been proposed to address this problem. In this paper, we present the deep description and implementation of “route optimization”, Authentication extension to mobile IP in the ns-2 simulator. We illustrate simulations of the mobile IP with route optimization with simulation scenarios, parameters, and simulations results.
