Abstract

Wireless sensor networks are a rising commodity that demonstrate merit in the research domain due to their versatile nature. While powerful and feature-laden, these systems also require careful configuration for optimal packet transmission. This experiment aims to examine these configurations. By varying clear channel assessment threshold (CCAT) values, it will be demonstrated through implementation that changing the thresholds influences overall efficiency. Conversely, it will be shown that mis-configuring a single node will only impact the network under certain conditions. This work may be parlayed into more elaborate energy conservation and transmission efficacy schemes.
