Rama Krishna  Abstract: The presence of errors and faults in systems is still a problem that needs to be handled. This paper tries to examine such a problem in the context of multi-agent systems. For solving it we analyze the use of two mechanisms: self-healing and self-organization, in order to manage fault at agent level as well as at the overall network infrastructure level. In order to realize these we proposed the use of adaptive agents which change state change their status according to the current situation and transmit their decisions to other agents by the means of a gossip communication protocol.
