Network virtualization has become one of the most prominent solutions that can efficiently deal with the dramatic increase of data demand in mobile networks. In order to allow multiple virtual networks to coexist in the same substrate network, the need for development of efficient virtual network embedding algorithms and techniques is imperative. The main purpose of this paper is to provide an optimization...
Network Mobility (NEMO) is becoming an important requirement for today's and tomorrow's IP networks. NEMO can give us internet connectivity while on the move. NEMO Basic Support Protocol (BSP) has been proposed by Internet Engineering Task Force (IETF) in order to address the need of mobile networks. But NEMO BSP has some limitations like inefficient route, high latency during handoff and packet delay...
Routing path restitution approach to control and tolerate the congestion in routing models for mobile ad hoc networks is proposed in this paper. Packet loss in network routing is primarily due to link failure and congestion. The majority of present congestion control solutions do not possess the ability to distinguish between packet loss due to link failure and packet loss due to congestion. Here...
With the rapid growth of wireless technologies and increasing number of mobile digital devices, mobility has been an important element on the Internet. NEMO Basic Support, designed by the Internet Engineering Task Force (IETF) to provide network mobility, is not efficient to offer low latency handoff in the case of nested mobile networks because it produces a long transfer delay and excessively large...
Cloud computing and ubiquitous network availability have renewed people's interest in the thin client concept. By executing applications in virtual desktops on cloud servers, users can access any application from any location with any device. For this to be a successful alternative to traditional offline applications, however, researchers must overcome important challenges. The thin client protocol...
In mobile ad hoc networks (or MANETs) devices usually rely on batteries, so the lifetime of these networks highly depends on the energy consumption of the devices composing them. In this paper, we improve the performance of the adaptive enhanced distance based broadcasting algorithm, AEDB, as well as we optimize it using a hybrid multi-objective algorithm, CellDE. The optimization is done by maximizing...
With the provisioning of interworked heterogeneous wireless networks and the growing popularity of smart mobile devices, ubiquitous service and data access is showing a demanding growth. As a result, scenarios of group mobility evolved with the increasing trend where a number of commuters on a transportation carriage would access such services. Making this scenario further complex, there was also...
Application-Layer Multicast (ALM) is considered a viable solution for compensating the lack of global IP Multicast deployment. While early ALM approaches consider only stationary end-systems, their use becomes more and more feasible on smaller devices like laptops and mobiles. Many ALM protocols have been proposed that employ multi-metric optimization strategies to consider e.g. delays, fanout-degrees,...
One or more mobile nodes with mobile router(s) form a mobile network. Mobile router acts as the single point of attachment to the internet. As the configuration of mobile network changes, mobile router keeps track of its registered mobile nodes. Presently, a scheme has been designed for group registration of mobile nodes under a single home agent. In this paper, a communication scheme is proposed...
The concept of wireless heterogeneous networks is based on the coexistence and interoperability of different types of radio access technologies in a unified wireless heterogeneous platform. A key process in the wireless heterogeneous networks is the initiation and execution of vertical handovers. Variety of mechanisms are proposed in the literature that are tailored to optimize the choice of radio...
During interdomain handover, IPv6 node has to acquire new address at its new location. Once the L2 handover procedure is completed, mobile node (MN) starts its IPv6 configuration, using stateless (router advertisements) or stateful (DHCPv6 communication) mode. After the address is obtained, its uniqueness has to be verified, using Duplicate Address Detection (DAD) procedure. Depending on the interface...
Due to widespread deployments of Vehicular Area Networks (VANs) and the increasing affordability of mobile data and smart mobile devices, there is an increasing demand for accessing applications and services on-the-go. As a result, group mobility scenarios have emerged, especially over VANs on public transport networks (e.g., buses, trains, aircraft, and so on). Therefore, when a group of users roam...
Among the route optimization schemes in NEtwork MObility (NEMO), the prefix delegation-based schemes perform better than other schemes. Since the prefix delegation-based schemes are designed for communication between a mobile network and a wired network, they lack evaluation for the case of intra mobile network communication involving MIPv6 incapable hosts in a mobile network. We evaluate prefix delegation-based...
The increase in proliferation of mobile devices and wireless technologies in recent years has opened up new challenges in mobile ad hoc networks (MANET). This growth has also led to an increase in demand of applications such as streaming video, multi-player interactive games and financial services such as real-time stock quotes. Such applications impose a strict guarantee on quality of service (QoS),...
Message Ferrying (MF) is a recently proposed scheme to restore a Mobile Ad Hoc Network (MANET) from partitioning. Despite of the effectiveness in partition restoration, it sometimes suffers from long delay caused by the poor design of ferry route. The Message Ferry Route (MFR) problem has earlier been studied to minimize this drawback of MF schemes. In this paper, we argue that a dynamic way of determining...
In cognitive mobile multihop relay (CMMR) network, the mobile user as the primary user is allocated with the channel for transmitting data. Relay station as the secondary user can help primary user to relay transmitted data while in return primary user grants channel access to secondary user. In this paper, credit-based spectrum sharing for primary and secondary user in CMMR network is proposed. With...
Much research has been devoted to maximize the life time of mobile ad-hoc networks. Life time has often been defined as the time elapsed until the first node is out of battery power. In the context of static networks, this could lead to disconnectivity. In contrast, Delay Tolerant Networks (DTNs) leverage the mobility of relay nodes to compensate for lack of permanent connectivity, and thus enable...
With the increase of the demands of mobile multimedia services, the real-time multimedia services such as IPTV often require the support of Mobile Multimedia Multicast (MMM) communications in the IP-based wireless networks. Since the MMM services often require a strict delay-bounded transport that guarantees quasi error free (QEF) transmission, we will investigate how to satisfy the QEF requirements...
An adhoc network is a collection of mobile nodes connected by a wireless link, where each node acts as a router. In order to facilitate the communication within the network, a routing protocol is needed. Due to bandwidth constraint and dynamic topology of the mobile adhoc networks supporting quality of service (QoS) is challenging task. The aim of this work is to present QoS enabled routing protocol...
Mobile IP (MIP) suffers from the so-called triangular routing problem. Moreover, MIP Home Agent (HA) tends to undergo server data traffic load, since it should deliver all the data packets toward mobile nodes. This Paper proposes a simple extension of MIP, called Query-based MIP (QMIP), in which the binding query to HA will be used to get the care-of address of a mobile node and to deliver the subsequent...
