With the development of Internet and the constant emergence of all kinds of multimedia business, user's demand on Quality of Service (QoS) becomes higher and higher. However, the current Internet routing protocol could not provide a good solution for QoS. Quality of service route is at present a very important research topic in the routing protocol, but it is hard to give a perfect method for network...
Ant colony optimization algorithm is widely used in various NPC problems for the global optimization, self learning ability and other characteristics, and achievements were made in WSNs field. Based on the study of Ant colony algorithm, in this paper, we propose a new energy-effective QoS routing algorithm. The algorithm is to speeds up the convergence of ant colony algorithm by using SNGF to optimize...
Secure routing issues, as a crucial research direction of security is emergent and significant in WSN. The existing QoS routing protocol ignores the security design. A secure QoS routing algorithm based on ACO is designed in this paper. This algorithm combines ant colony optimization algorithm with credit evaluation mechanism effectively. In order to achieve good security performance, the creditworthiness...
In Low power and Lossy Networks (LNNs), routing has been considered as a main design and development challenge. This has led to the open design of the IPv6 routing protocol for LLNs called RPL. The protocol allows creating groups (instances) of multiple loop-free routing topologies over a physical network. The purpose of forming an optimized tree routing topology is to drive packets from the nodes...
This paper explores the feasibility of Exascale Cloud Computing over the Nobel-EU (European Union) IP backbone network. The EU represents an attractive environment for Exascale Cloud Computing, due to its well-established IP infrastructure with relatively low edge distances. An Exascale Cloud Computing system linking hundreds of data-centers can interconnect potentially millions of servers, considerably...
Recent advances in information and communication technology resulted in increased use of multimedia applications. Multimedia transmission over Mobile Adhoc Networks (MANETs) with high Quality of Service (QoS) is a challenging task due to mobility of the nodes. The problems associated with multimedia transmission are loss of packets or frames and delay in receiving the packets at destination. To maintain...
This paper deals with the characteristics of MANET and issues of the quality of service support with using the DSDV routing protocol. In this paper, the creation of the process model of MANET with DSDV routing protocol in a simulation environment NS-3 and its complement of QoS support are elaborated. The implementation of QoS support algorithms is verified by the functional simulation model and consequently...
The field of wireless multimedia sensor networks (WMSN) is attracting more and more research community as an interdisciplinary field of interest. This type of network is low-cost, multifunctional due to advances in micro-electromechanical systems, and the proliferation and progression of wireless communications. However transmit multimedia information captured must satisfy the criteria of QoS , which...
In wireless ad hoc networks such as Vehicular Ad Hoc Networks (VANET), limited coverage of WiFi and high mobility of the nodes generate frequent topology changes. Therefore Quality of Service (QoS) support becomes an essential aspect. In this work we have identified the need for QoS improvement in VANETs. Survey of related work depicts that, an efficient routing strategy plays a crucial role, to improve...
This paper presents a source based power-aware reactive routing protocol for Mobile Ad hoc Networks (MANETs). It considers Quality of Service (QoS) parameters namely delay, throughput, bandwidth and cost of each link. Recent advances in MANETs have led to many new routing protocols specifically designed for mobile devices. Almost all of these routing protocols considered energy efficiency as the ultimate...
Providing QoS in the context of Ad Hoc networks includes a very wide field of application from the perspective of every level of the architecture in the network.In order for simulation studies to be useful, it is very important that the simulation results match as closely as possible with the test bed results. In this Paper, we study the throughput performance(parameter QoS) in Mobile Ad Hoc Networks...
Mobile ad hoc network is coordinated without fixed infrastructure. In the conservative AODV routing protocol, source node always forwards RREQ (Route Request) packet to neighbour for finding path to the destination node. The intermediary (neighbour) node having less lifetime or energy, as well forwards RREQ and lifetime expires after some certain time, i.e. node goes down; it cannot forward RREP (Route...
A proposal to use flow switching over a national network was studied in this paper to investigate its feasibility against the other solutions of switching. National Science Foundation Network (NSFNET) has been considered here and supposed to be optically switched in its core. This network has been analyzed against different types of traffics. All the switches are assumed to be OpenFlow switches to...
The Internet has recently seen the emergence of new value added services (IPTV, VoIP, etc‥), that require Quality of Service (QoS) guarantees. Given the nature of the Internet, most of the time, the source and the destination are connected to different providers, so that multiple ISPs must cooperate in order to offer end-to-end QoS guarantees. All this without revealing how each provider implements...
Mobile Ad Hoc Networks have been deployed in a wide spectrum of domain ranging from military battlefields, natural disaster and manmade disaster management, conference, home networking, patient monitoring, remote landscape monitoring to name a few. MANET being an infrastructureless network with its inherent features like self-configuration, self-organizing and self-administration, it has been focus...
In the past, many researchers depend highly on various real life environmental short coverage area networks to analyze the performance of various routing algorithms. Recent ever-increasing interest in vehicular ad hoc network communication (VAC) necessitates vehicular movement performance study via different mobility pattern simulation. Unlike many other works, we present a study on the performance...
Stable and efficient routing plays a key role for the success of VANETs. Road-based routing has been shown well-suited for urban VANETs, and multipath routing provides alternative routes once the current route fails. However, existing multipath routing protocols are node-based, which are not suitable for urban VANETs. In this paper, we propose a road-based QoS-aware multipath routing protocol for...
Several Routing Protocols have been proposed and developed in the last few years for Wireless Sensor Networks (WSNs).
