Due to the progress of network multimedia technology, a majority of real-time multimedia applications need multicast communication to transmit information. These applications require a multicast routing protocol in which packets arrive to multicast receptors within a specified QOS guaranteed. D2V-RPS's problem (delay and delay variation RP Selection) consists in choosing an optimal multicast router...
Merging IP routing and mobile communication poses many challenges especially for a dynamic, heterogeneous networking environment such as a Naval Task Force. In this paper, we present an effort to design, develop, test and demonstrate an interoperable coalition interface for a Naval Task Force for the four-nation Coalition Networks for Secure Information Sharing (CoNSIS) project. A field experimentation...
IP/MPLS based ASON/GMPLS networks enable the interaction between the IP layer and the optical WDM layer. Furthermore, it decouples the physical topology from the dynamically created IP topology, which is called Virtual Topology. In this network architecture, there are two known routing policies, they are the Physical Topology First (PTF) and Virtual Topology First (VTF). PTF and VTF are different...
Wireless Multimedia Sensor Networks (WMSNs) is a novel information acquiring and processing technology which is more competent than traditional sensor networks in transferring and processing of huge amount of multimedia information data, such as audio, video, images and so on. It plays critical role in application in civil, military and commercial fields. In this paper, a Non-control sorting method...
In this paper, we present a new vehicular paging procedure for fast selection of vehicular relay node cells on access link to connect seamlessly vehicles equipped with an Long Term Evolution (LTE) communication module to the infrastructure. The proposed Radio Resource Control (RRC) protocols allows fast radio bearer setup in the Vehicular User Equipment (V-UE) without need to re-establish the Access-Stratum...
This paper proposes a proof-of-concept demonstration of the hierarchical routing management (HRM) system as a new routing management approach for application requirement oriented routing. Its main goal is the improvement of packet routing in order to optimize networks for future multimedia streaming. Application data streams are directed by the HRM system along paths, which provide only those network...
A recent trend in routing research is to avoid inefficiencies in network level routing by allowing hosts to either choose routes themselves (e.g., source routing) or use overlay routing networks. Such end-to-end route selection schemes are selfish by nature, in that they allow end users to greedily select routes to optimize their own performance without considering the system-wide criteria. Recent...
In this paper we investigate the network lifetime maximization problem in a delay-tolerant wireless sensor network with a mobile sink by exploiting a nontrivial tradeoff between the network lifetime and the data delivery delay. We formulate the problem as a joint optimization problem that consists of finding a trajectory for the mobile sink and designing an energy-efficient routing protocol to route...
Networks-on-Chip have shown their scalability for future many-core systems on chip. In real world scenarios, concurrent applications with different QoS requirements affect each other through overlapping communication. Therefore computation resources may not be efficiently utilized because the required communication resources are already occupied. Hence, an efficient resource management strategy is...
A mobile ad hoc network (MANET) consists of mobile wireless nodes. The communication between these mobile nodes is carried out without any centralized control. The ease of deployment and the infrastructure less nature of Mobile Ad hoc Networks (MANETs) make them highly desirable for the present day multi media communications. Traditional routing protocols may not suffice for real time communications...
A multicommodity Minimum-Cost Maximum-Flow algorithm for routing multiple unicast traffic flows in infrastructure wireless mesh networks, represented as commodities to be routed in an undirected or directed graph, is presented. The routing-cost per edge can be any metric, i.e, a delay, a SNR, etc. To minimize resource-usage and transmission power, the routing-cost is formulated as a Bandwidth-Distance...
In this paper, we investigate a cross layer design for routing in mobile ad hoc networks. The goal is to improve the performance of the existing Ad-hoc On Demand Distance Vector (AODV) routing protocol. The design allows the physical layer sharing the received signal strength (RSS), and the medium access control (MAC) layer sharing the remaining energy, as well as the remaining queue length information...
In tactical environment, MANET (Mobile Ad Hoc Network) has the network characteristics which make highly dynamic nodes, self-organized in fully-distributed style. Also, it has a harsh wireless channel environment compared to the commercial networks. In these channel environments, optimal path decision suited for Quality of Service (QoS) of transmitted tactical traffics must be performed by recognizing...
As Internet Protocol version 4 (IPv4) addresses deplete, Internet Protocol version 6 (IPv6) is introduced to alleviate the depletion with introduction of much needed functionality in security and so much more. Quality of Service (QoS) has been one of the aspects taken into consideration for improving network performance such as Packet Delivery Fraction (PDF), average End-to-end Delay and throughput...
An advanced multimedia system is being standardized in ITU-T SG16. One of the primary features of the multimedia system is the inclusion of QoS functions from the outset. This paper presents a possible QoS framework for the multimedia system, which permits multimedia applications to request and acquire QoS for its applications in multi-provider networks. The presented framework is independent of the...
With the ever increasing demand of multicasting on the Internet, the interest in deploying multicast for distribution of these contents have increased. To evaluate the performance of multicast protocols many efforts have been put into defining multicast metrics. This paper defines the performance metric for evaluation of multicast protocols DVMRP, MOSPF, PIM-SM, PIM-DM and CBT and also outlines the...
Network throughput and bandwidth overprovisioning do not provide equal quality of service for all applications. Time characteristics of the network must also be taken in mind when deploying applications which are sensitive to delay and jitter, e.g. VoIP. By means of changing the path of traffic significant improvement of the time-variable can be achieved. In this paper we propose a methodology for...
In this paper, an energy-efficient, distance-aware and QoS-guaranteed multi-path routing (EDQMR) protocol for WVSNs is proposed. The routing selecting and updating algorithm is designed under comprehensive consideration of the hop count, delay, the distance between hops and energy information. The path of the largest minimum residual node energy is used as an alternate path to increase the network...
Now-a-days the Most of the Computer systems work in a network and the routing of the packets efficiently and pace fully is required to maintain the performance of the system. The performance of the system may vary from user to user as simple routing can work for simple transferring but as the new era techniques of come into existence new parameters came into existence like the bandwidth requirement...
Network-on-chip (NoC) is a new solution for multi-core interconnection. The static virtual channel allocation and XY routing are regularly used by the 2D mesh NoC. But the inter-core transmission congestion increases the transmission delay and decrease the throughput, which depredates the cooperation of multiple cores. This paper proposes a QoS mechanism and designs the router architecture by dynamic...
