- Conflict-Aware Load-Balancing Techniques for Database Replication
- Middleware-based database replication protocols are more portable and flexible than kernel-based protocols, but have coarser-grain information about transaction access data, resulting in reduced concurrency and increased aborts. This paper proposes conflict-aware load-balancing techniques to increase the concurrency and reduce the abort rate of middleware-based replication protocols. Experimental evaluation using a...

- Joint MAC-Aware Routing and Load Balancing in Mesh Networks
- Past approaches to routing in mesh networks either do not account for the MAC-layer interactions between the links in a tractable manner, or are agnostic to load-balancing across gateways. The answer to these problems is MaLB (MAC-aware and Load Balanced routing algorithm), a greedy tractable, and distributed mesh routing algorithm....

- On Optimal Probing for Delay and Loss Measurement
- Packet delay and loss are two fundamental measures of performance. Using active probing to measure delay and loss typically involves sending Poisson probes, on the basis of the PASTA property Poisson Arrivals See Time Averages, which ensures that Poisson probing yields unbiased estimates. Recent work, however, has questioned the utility...

- An Experimental Study on the Capture Effect in 802.11a Networks
- In wireless networks, a frame collision does not necessarily result in all the simultaneously transmitted frames being lost. Depending on the relative signal power and the arrival timing of the involved frames, one frame can survive the collision and be successfully received by the receiver. Using the IEEE 802.11a wireless...
