Resumen
A wireless mobile network is characterized by shortage of resources, such as transmission
range and energy consumption. This network has the advantage to use all the
potencial of mobile devices, like PDAs and portable computers, for example. On the
other hand, these networks are more vulnerable to errors and failures. However, techniques
of fault tolerance can be used to skirt them. The failure detector is a distributed
algorithm that supplies informations about failures suspicion in monitored components.
The failure detector is an important building block for the implementation of fault tolerance
techniques. In this context, this work reviews the characteristics of the main failure
detection algorithms for wirelessmobile networks and compare them through tests carried
out in a simulator.
