RESUMO

The inherent characteristics of ad hoc networks such as the lack of infrastructure and the possibility of multi-hop links require performance measures that capture the relationships between physical layer, medium access control and link layer. Based on aggregate information efficiency metric and packet delay, trade-offs involving several networks variables are analyzed. It is shown that the possibility of packet retransmission improves the network performance. In networks where part of the active links is in outage, the best results are found for outage probabilities between 50% and 80%. Concerning multi-hop links, the results show that it is preferable having transmissions with a greater number of hops formed by receptor terminals that require higher threshold powers for a packet reception
