Evaluation Of Energy Release From Wildfires Across The Elevation Gradient, Isabelle Rose Butler

Boise State University Theses and Dissertations

Wildfires are an integral process in vegetative terrestrial land which shape ecosystem functions. A warming climate, however, has increased the size and severity of fires with significant ecosystem and societal implications. Furthermore, warming has changed characteristics of wildfires enabling a median upslope advance of 252 m in high-elevation forest fires from 1984 to 2017, allowing wildfires to burn in areas that were previously too wet to burn frequently. This exposed an additional 81,500 square kilometers (11%) of western US montane forests to fires.

In this thesis, I test the hypothesis that wildfires burn more intensely in high-elevation mesic forests than …

Congestion Avoidance Energy Efficient Mac Protocol For Wireless Sensor Networks, Alexander Sundling

Boise State University Theses and Dissertations

Wireless Sensor Network (WSNs) are generally energy-constrained and resource-constrained. When multiple simultaneous events occur in densely deployed WSNs, nodes near the base station can become congested, decreasing the network performance. Additionally, multiple nodes may sense an event leading to spatially-correlated contention, further increasing congestion. In order to mitigate the effects of congestion near the base station, an energy-efficient Media Access Control (MAC) protocol that can handle multiple simultaneous events and spatially-correlated contention is needed. Energy efficiency is important and can be achieved using duty cycles but they could degrade the network performance in terms of latency. Existing protocols either provide …
