Tradeoff Between Energy and Latency for Convergecast
We focus on the problem of energy-efficient convergecast in sensor networks. This problem identifies the energy-latency tradeoff during convergecast. We show how time division multiple access (TDMA) can be effectively used to provide energy-efficient convergecast. This solution allows the sensors to save energy when the network is idle and to switch to active mode when the network observes an event.

Approximate Causal Observer
In this paper, we focus on the problem of approximate casual delivery. This problem identifies the tradeoff between causal delivery and timely delivery of messages. Causal delivery requires that delivery of a message, say m, be delayed until all messages on whom m is causally dependent are delivered. By contrast, timely delivery requires that messages be delivered as soon as possible.
