Previous: Maximum Connectivity in MultiNet
We summarize the conclusions of our performance analysis as follows:
- No single switching strategy is best under all circumstances. Adaptive strategies are best when no network preference is indicated. Both Adaptive Buffer and Adaptive Traffic give similar performance
- For the applications studied, MultiNet consumes 50% less energy than a two card solution.
- As expected, the average packet delay with MultiNet varies linearly with an increase in the number of connected networks when all the networks are given equal activity periods.
- Masking `media connects' and `media disconnects' below IP leads to significant reduction in the switching overhead. The switching delay for legacy cards is reduced to around 300 ms, while this number goes down to 30 ms for Native WiFi cards.
- Adaptive Switching eliminates the current zero configuration requirement to prioritize the preferred network. With MultiNet based zero configuration, the user connects to all preferred networks.
