ADAPTIVE NETWORKING PROTOCOL FOR RAPID MOBILE ENVIRONMENTS
This dissertation presents two novel contributions in the area or wireless networks. The first one, the Rapid-Mobility Network Emulator (RAMON), was targeted to study the performance of wireless protocols at high speed, evaluate handoff, and IEEE 802.11x technologies. RAMON is a development platform that combines emulation and simulation, and facilitates the analysis of performance bottlenecks in a quicker and more efficient matter. Additionally, RAMON recreates more realistic environments for wireless network protocols where attenuation, latency delay, and bandwidth can be modified as required by the experimenter. The second contribution is a predictive extension for Mobile IP using a Kalman filter. The forecasting of speed and trajectory allows the protocol to avoid late registration and improve performance at high speed. We added two new entities to the protocol: the ghost-mobile node and ghost foreign agent. The entities preemptively react to the environment and allow much faster and quicker handoff. The predictable protocol improves the performance of Mobile IP and proves the feasibility of a wireless network infrastructure for vehicles traveling at speeds of up to 80 m/sec or 288 km/hr. .
Low latency IP mobility management: protocol and analysis
Eurasip Journal on Wireless Communications and Networking, 2011
Mobile IP is one of the dominating protocols that enable a mobile node to remain reachable while moving around in the Internet. However, it suffers from long handoff latency and route inefficiency. In this article, we present a novel distributed mobility management architecture, ADA (Asymmetric Double-Agents), which introduces double mobility agents to serve one end-to-end communication. One mobility agent is located close to the MN and the other close to the CN. ADA can achieve both low handoff latency and low transmission latency, which is crucial for improvement of user perceived QoS. It also provides an easy-to-use mechanism for MNs to manage and control each traffic session with a different policy and provide specific QoS support. We apply ADA to MIPv6 communications and present a detailed protocol design. Subsequently, we propose an analytical framework for systematic and thorough performance evaluation of mobile IP-based mobility management protocols. Equipped with this model, we analyze the handoff latency, single interaction delay and total time cost under the bidirectional tunneling mode and the route optimization mode for MIPv6, HMIPv6, CNLP, and ADA. Through both quantitative analysis and NS2-based simulations, we show that ADA significantly outperforms the existing mobility management protocols.
Mobility Management Using the IP Protocol
International Journal of Advanced Computer Science and Applications, 2018
Time critical applications, such as VoIP and video conferencing require Internet connectivity all of the time for better performance. Moreover, in case of vehicular networks, it is very common for mobile devices to move from one network to another. In such scenarios the sudden changes in the network connectivity may cause problems, which affects the data transmission rate. The movement of a mobile node from one network to another is also a challenge for the routers to maintain the routing information as well as to forward the data to the corresponding node. In all of the aforementioned scenarios, the switching between the networks with minimum latency improves the performance, i.e. in terms of mobility and availability of the network. The Mobile IP protocol serves the purpose of seamless handover of mobile devices from one network to another. A mobile node maintains its permanent IP address using the Mobile IP protocol while moving to a foreign network. When a mobile node establishes the connection with the foreign network the data packets transmitted from the home network are redirected to the foreign network. The Mobile IP protocol establishes a tunnel between the home network and the foreign network. The process of tunneling continues until the mobile node moves back to the home network or when the foreign network advertises the new IP address of the mobile node. With the increasing number of wireless devices the mobility is the key challenge. The devices with multiple interfaces such as mobile phone which uses 4G as well as WiFi, the urge for the availability of the Internet is also high. This paper provides a deep discussion about the Mobile IP protocol and its implementation. A network scenario is proposed with the configuration of the Mobile IP. According to the obtained results of the simulations, the Mobile IP protocol increases the availability of the network connection as well as it achieves the larger throughput when compared with the scenario without using the Mobile IP.
Improving TCP Performance in Mobile Ad Hoc Networks Using Mobility Prediction
In mobile ad hoc networks node movements induce frequent topology changes. Therefore, traffic paths are often interrupted, until an ad hoc routing protocol recovers the path failure. These disruptions have negative impact on the network throughput, particularly when the transport protocol is TCP. In this paper we analyze the effect of route disconnections on TCP performance and present a routing protocol enhancement, called TCP-HOT to overcome route disruptions using a mobility prediction based route handoff prior to route failure. Through simulations we show that mobility prediction based route handoff can improve the performance of ad hoc networks in sense of throughput increase. The method can be deployed in the nodes without requiring any change in the current TCP/IP stack.
Predictive mobile IP handover for vehicular networks
2015 IEEE 40th Conference on Local Computer Networks (LCN), 2015
Vehicular networks are a rapidly growing technology with vehicle manufacturers already taking steps for its implementation. However, adding IP services to vehicular networks remains an issue. This is in part due to the mobile IP handover causing overhead and latencies unsuitable for the faster movement of vehicles. Frequent topological changes caused by this movement require smooth IP handovers due to the regularity in which they occur. In this paper, we propose a predictive handover utilizing a movement prediction method to conduct the costly handover ahead of time, thus providing a consistent IP connection. The approach is tested and compared in a variety of simulated vehicle network environments. Results show an overall improvement in network performance with handover latency greatly reduced.
TeleMIP: telecommunications-enhanced mobile IP architecture for fast intradomain mobility
IEEE Personal Communications, 2000
This article first surveys existing protocols for supporting IP mobility and then proposes an extension to the Mobile IP architecture, called TeleMIP. Our architecture attempts to achieve smaller handoff latency by localizing the scope of most location update messages within an administrative domain or a geographical region. TeleMIP is intended for use in evolving third-generation wireless networks, and introduces a new logical entity, called the mobility agent, which provides a mobile node with a stable point of attachment in a foreign network. While the MA is functionally similar to conventional foreign agents, it is located at a higher level in the network hierarchy than the subnet-specific FA. Location updates for intradomain mobility are localized only up to the MA; transmission of global location updates are necessary only when the mobile changes administrative domains and/or geographical regions.
Fast handoff with position information for mobile IP
2002
Mobile IP is designed to support uninterrupted connectivity of mobile computers as they roam from place to place. We propose a fast intra-domain and inter-domain handoff scheme using the location of routers to meet the delay and packet loss requirements of real-time services. The scheme achieves an intelligent and dynamic neighborhood discovery and avoids the use of multicast addresses in intra-domain handoff. In addition, it decreases the registration time and distributes home agent data base dynamically in inter-domain handoff depending on how far from the home agent mobile host is. Simulation and implementation results for an interactive voice communication are presented.
IP-based protocols for mobile internetworking
Computer Communication Review, 1991
We consider the problem of providing network access to hosts whose physical location clianges with time. Such hosts cannot depend on traditional forms of network connectivity and routing because their location, and hence the route to reach them, cannot be deduced from their network address. In this paper, we explore the concept of providing continuous network access to mobile computers, and present a set of IP-based protocols that achieve that goal.
A predictive low latency handover scheme for Mobile IP
2005
Many wireless protocol simulation studies are performed under the assumptions that (i) nodes travel in a random fashion in unobstructed environments, and that (ii) radio wave propagation modeling is based on the freespace principle. We propose an urban mobility model, where mobile nodes traverse city streets using a variety of movement modes and where the urban environment is used as an input in the radio wave propagation modeling process.
Implementation of Prediction Algorithm in Mobile IP Handover for Vehicular Networks
Vehicular networks are emerging technology that offers potential for providing a variety of new services. Vehicles are connected through Mobile IP but due high speed of vehicles mobile IP handover is a problem. The handover process, consisting of discovery, registration, and packet forwarding, has a large overhead and disrupts connectivity. With increased handover frequency and smaller access point dwell times in vehicular networks, the handover causes a large degradation in performance. This paper proposes a predictive handover solution, using a combination of a Kalman filter and hidden Markov model, to minimize the effects of prediction errors and to capitalize on advanced handover registration.To evaluate the effectiveness of the proposed methodMATLAB simulationsare carried out.Results show an overallimprovement in network performance with handover.
