Current intra-domain routing protocols computes only shortest paths for any pair of nodes which cannot provide good fast reroute when network failures occur. Multipath routing can be fundamentally more efficient than the currently used single path routing protocols. It can significantly reduce congestion in network by shifting traffic to unused network resources. This improves network utilization...
The Internet is playing an increasingly crucial role in both personal and business activities. Handling link failures is an important task in designing routing protocols. To enhance the network availability without incurring significant extra overhead, we propose a novel link protection algorithm, Hybrid Link Protection Scheme (HLP) to achieve failure resilient routing.
The Wireless Sensor Converge-cast Networks (WSCNs) are widely applied in many fields such as medical applications and environmental monitoring. The monitoring data are collected from the sensors and gathering toward the sink node. A coding aware routing scheme based on Connected Dominating Set is provided. Based on CDS, a coding condition, named Improved Coding Conditions (ICC), is defined with an...
Cloud service based on data center (DC) has become an attractive choice for abundant applications. Generally, DCs are distributed at different nodes across a given optical network, and users access DCs through predefined routes. From the perspective of service providers, it is important to offer reliable cloud service while taking service delay and service cost into consideration. In this paper, we...
Resource discovery is a challenging issue in Grid. A large number of mechanisms have been proposed for resource discovery based on the graph and tree method, but less attention has been paid to the dynamism of the Grid environment, the integrity of the system, reliability and quality of service. In this paper a new mechanism (DBTT) is proposed for resource discovery, which can include these criteria...
There is a need for reliable and trustworthy public transport planner services. Mass transits are trying to solve problems as traffic jams or increasing pollution in densely populated city agglomerations. Passengers are looking for travel information on-line and companies providing public transport solutions often struggle with providing modern trip planner platforms. We address this problem by providing...
Data delivery of packets in broad cast using wireless medium is the main intention of this paper, this will be done through a MANETS and should achieve reliable delivery. This paper addresses the problem of delivering data packets for highly dynamic mobile ad hoc networks in a reliable and timely manner. The process of routing the data packets to the destination is a challenging task. In order to...
The Temporally-Ordered Routing Algorithm (TORA) is a distributed routing protocol that is based on a family of link reversal algorithms. TORA is able to provide multiple loop-free routes to any destination using the route creation, maintenance and erasure functions. TORA performs well in networks with a small number of traffic connections but poorly in networks with a large number of traffic connections...
This paper proposes a reliability-admissible filtering mechanism to generate the reasonable route set for the traditional SUE model. This mechanism still takes into account traveler's cost-susceptivity, which is able to dispel the impact of dimension on the traffic assignment. The filtering formula is presented and further estimated based on the Gumbel distribution assumption for the route disutility...
Network planning is one of the important content in the distribution network. In order to increase the reliability of power supply, to ensure voltage quality, and to reduce power loss, network planning method for distribution systems is proposed to form radial network automatically based on the planning analytical foundation. According to the load moment, the method is presented to partition power...
To the problem of hostile service brought by node anonymity in P2P system, this thesis proposes a reputation aware resource finding algorithm. This algorithm is based on routing indices (RIs) algorithm and adopts the conception of reputation to efficiently restrain the deceiving behavior of hostile nodes in P2P system and reduce the messages load in the system, which can ensure the reliability and...
In this paper a BISR architecture for embedded memories is presented. The proposed scheme utilises a multiple bank cache-like memory for repairs. Statistical analysis is used for minimisation of the total resources required to achieve a very high fault coverage. Simulation results show that the proposed BISR scheme is characterised by high efficiency and low area overhead, even for high defect densities...
Networks on chips (NoCs) provide a mechanism for handling complex communications in the next generation of integrated circuits. At the same time, lower yield in nano-technology, makes self repair communication channels a necessity in design of digital systems. This paper proposes a reliable NoC architecture based on specific application mapped onto an NoC. This architecture is capable of recovering...
Expected growth in use and implementation of wireless sensor networks (WSNs) in different environments and for different applications creates new security challenges. In WSNs, a malicious node may initiate incorrect path information, change the contents of data packets, and even hijack one or more genuine network nodes. As the network reliability completely depends on individual nodespsila presence...
This paper proposes a fast forward medium access control protocol (FFMAC) for quality-of-service (QoS) guarantee in multihop IEEE 802.11s wireless mesh networks with multiple channels. To the best of our knowledge, the proposed protocol is the first one which considers the multihop and multichannel issues simultaneously. It provides higher priority for real-time applications, while remaining the distributed...
