the distributed computing scenario is rapidly evolving for integrating self-organizing and dynamic wireless networks. Unreliable failure detectors are classical mechanisms which provide information about process failures and can help systems to cope withthe high dynamism of these networks. A number of failure detection algorithms has been proposed so far;nonetheless, most of them assume a global knowledge about the membership as well as a fully communication connectivity;additionally, they are timer-based, requiring that eventually some bound on the message transmission will hold. these assumptions are no longer appropriate to the new scenario. this paper presents a new failure detector protocol which implements a new class of detectors, namely. lozenge S-M, which adapts the properties of the lozenge S class to a dynamic network with an unknown membership. It has the interesting feature to be time-free, so that it does not rely on timers to detect failures;moreover, it tolerates mobility of nodes and message losses.

In the multi-user multiple input multiple output broadcast channels (MIMO BC), single-antenna mobile users (as receivers) are quite common due to the size and cost limitations of mobile terminals. We simply term this ...
