Abstract

We study how selfish nodes react to transmission costs in wireless networks. Intuitively, it seems that transmission costs should have a stabilizing effect as (rational) nodes will defer packet transmissions when congestion develops and the cost for (successfully) transmitting a packet becomes high. In this paper we investigate whether this intuition is true. We use slotted Aloha to model the communication channel.
