- A Comparison of MPICH Allgather Algorithms on Switched Networks
- The study discussed in this paper evaluates the performance of MPI_Allgather in MPICH 1.2.5 on a Linux cluster. This implementation of MPICH improves on the performance of allgather compared to previous versions by using a recursive doubling algorithm. A dissemination allgather is developed based on the dissemination barrier algorithm. This...

- Dissemination of Heterogeneous XML Data
- A lot of recent research has focused on the content-based dissemination of XML data. However, due to the heterogeneous data schemas used by different data publishers even for data in the same domain, an important challenge is how to efficiently and effectively disseminate relevant data to subscribers whose subscriptions might...

- Sampling Strategies for Epidemic-Style Information Dissemination
- This paper considers epidemic-style information dissemination strategies that leverage the non-uniformity of host distribution over subnets (e.g., IP subnets) to optimize the information spread. Such epidemic-style strategies are based on random sampling of target hosts according to a sampling rule. The objective of this paper is to optimize the information...

- Performance of Data Dissemination Among Mobile Devices
- This paper presents 7DS, a novel peer-to-peer data sharing system. 7DS is an architecture, a set of protocols and an implementation enabling the exchange of data among peers that are not necessarily connected to the Internet. Peers can be either mobile or stationary. It anticipates the information needs of users...

- D3: Data-Centric Data Dissemination in Wireless Sensor Networks
- This paper presents a novel method to disseminate sensor data in a wireless sensor network, called D3 (Data-centric Data Dissemination). The method combines the advantages of data-centric routing like SPIN and directed diffusion and energy-efficient MAC protocols such as S-MAC and T-MAC. The protocol's strengths are its energy-efficiency and its...

- Data Dissemination With Ring-Based Index for Wireless Sensor Networks
- In wireless sensor networks, sensor nodes are capable of not only measuring real world phenomena, but also storing, processing, and transferring these measurements. Many techniques have been proposed for disseminating sensing data. However, most of them are not efficient in the scenarios where a huge amount of sensing data are...

- On the Effectiveness of Automatic Patching
- This paper studies the effectiveness of automatic patching and quantifies the speed of patch dissemination required for worm containment. The paper focuses on random scanning as this is representative of current generation worms, though smarter strategies exist. The paper finds that even such "Dumb" worms require very fast patching. The...

- Local On-Line Maintenance of Scalable Pub/Sub Infrastructure
- A publish-subscribe infrastructure supports the dissemination of varied information to a large population of users with individual preferences. This paper focuses on topic-based publish-subscribe systems, where users can subscribe to topics of interest, and receive all updates related to these topics. One notable application of such systems is real-time dissemination...

- Exploring the Energy-Latency Trade-Off of Broadcasts in IEEE 802.11 Power Save Networks
- Efficient information dissemination is essential for the operationality of sensor networks. However, one of the challenges to efficient information dissemination arises from only a random subset of nodes being active in any given time. This is mainly due to sensor networks employing power-saving techniques to compensate the energy constraints of...

- Secure Diffusion for Wireless Sensor Networks
- Data dissemination is an indispensible protocol component for the emerging large-scale sensor networks. This paper proposes a secure data dissemination protocol that enhances directed diffusion to operate in the presence of compromised sensors. The proposed solution, Secure Diffusion, utilizes a novel security primitive called location binding keys, and exploits the...

- Handling Client Mobility and Intermittent Connectivity in Mobile Web Accesses
- Wireless devices are being increasingly used to access data on the web. Since intermittent connectivity and client mobility are inherent in such environments, this paper examines the impact of these factors on coherent dissemination of dynamic web data to wireless devices. The paper introduces the notion of eventual-delta consistency, and...
