Diversity, Stability, and Symmetry of Routes in a Wireless Mesh Network

Routing is the process of finding paths in an internetwork that is highly dynamic. Depending on the routing metrics, external interference, and internal factors, the routes might change in diversity, stability, and symmetry over time. There are several studies of these issues which consider the Internet where the routes are determined by interior and exterior gateway protocols. Mobile Ad-hoc Networks (MANETs) and Wireless Mesh Networks (WMN) are not comparable to the Internet; not only due to their much smaller size but because of the different approaches used for routing, the different network topology, and the (most often) absence of traffic engineering. We expect them to show a different behavior.

Several ad-hoc routing protocols have been implemented based on our DES-SERT routing framework. Although there have been some experiments which gave insight in the behavior of these protocols in a real world environment, we lack more detailed information. Therefore a study is required that repeats particular Internet-based experiments in our testbed.

Objectives

• get familiar with the DES-Testbed
• research which experiments have been executed in the Internet
• specify experiment methodology
• use, port, or develop tools for experiments
• specify scenarios with different traffic patterns
• run experiments in the testbed
• evaluate your measured data
