The document discusses key issues in designing ad-hoc wireless routing protocols. It outlines challenges like mobility, bandwidth constraints from a shared radio channel, and hidden/exposed terminal problems. It also notes resource constraints from limited battery, processing power, and size. The document proposes ideal characteristics for routing protocols, including being fully distributed, adaptive to topology changes, loop-free, and minimizing overhead through localized routing and limited broadcasts. It suggests protocols should converge quickly and use resources sparingly.
