摘要：

We consider arbitrary traffic patterns in arbitrarily placed extended wireless networks. We provide sufficient conditions for the approximate optimality of multi-hop communication over such networks. For exponential power decay, we show that these sufficient conditions are always satisfied, resulting in a scaling characterization of the entire capacity region for any node placement.
