Parameters: performative - An integer identifying the FIPA performative to be set to this FIPA performatives provide an outline for the existence and action of agents. Existing FIPA protocols have been described through Petri-nets but the timing aspect was not speciﬁed which was a limitation. The main idea of this research is to formally model the existing FIPA performatives by Timed Arc Petri-Nets (TAPNs) in real-time multi-agent 1.1 Performatives The FIPA standard SC00037J [9] deﬁnes 22 “Communicative Act” names as values for the performative ﬁeld (see Table 1). In implementing our agent infrastructure, CASA [13], we have found that the FIPA performatives were very useful in that they include communicative acts that we would not have initially thought of ourselves. FIPA-ACL defines different performatives for communication among the agents. These performatives are generic, and it becomes computationally expensive to 1.1 Performatives The FIPA standard SC00037J [9] deﬁnes 22 ”Communicative Act” names as values for the performative ﬁeld (see Table 1).

There are 22 FIPA performatives which … FIPA_ERROR Fipa performative enum value FIPA_ZERO Fipa performative enum value FIPA_ACCEPT_PROPOSAL Fipa performative enum value FIPA_AGREE Fipa performative enum value FIPA_CANCEL Fipa performative enum value FIPA_CALL_FOR_PROPOSAL Fipa performative enum value In this example you can see how the RecvBehav behaviour receives the message because the template includes a performative with the value inform in the metadata and the sent message does also include that metadata, so the message and the template match..

For example, the following message was sent by agent (turtle) 5 to agent 3, its content is “fire-at [23 15]” and the message performative (FIPA) is “inform”.

The class provides a method to introduce metadata into messages, this is useful for using the fields present in standard FIPA-ACL Messages. When a message is ready to be sent, it can be passed on to the send() method of the behaviour, which will trigger the internal communication process to actually send it to its destination. What is FIPA? The FIPA standard is an agent oriented programming abstraction: A standard for defining heterogeneous and interacting agents.

Taken together the set of performatives . In the former (the KQML way), the wrapper language has a specific achieve performative for achieving goals, as it does not assume the content language necessarily has this capability. In the latter case (the FIPA-ACL way), the achieve performative is pushed into the content language, thus eliminating the need for the same in the ACL.

To achieve these features, agents have to transfer messages in the predefined In FIPA ACL there are some performatives, such as proposal, CFP and so on, for general agent negotiation processes, but they are not sufficient for our purposes. performatives and prot ocols of FIPA’97 ACL from th is point of view.

The ACL specification defines a set of 22 performatives and their meaning. FIPA ACL Performatives Negotiation accept-proposal sender accepts proposal made by other agent cfp call for proposals; initiates negotiation between agents; content-parameter contains action (desired to be done by some other agent) (e.g.: „sell me car“) and condition (e.g.: „price < 1000$“) reject-proposal sender does not accept proposal For performatives supported by GAMA (i.e., standard FIPA performatives), please use the 'action' with the same name of 'performative'. For example, to reply a message with a 'request' performative message, the modeller should use the 'request' action. returns: unknown; message (message): The message to be replied inform FIPA performatives. The goal of both the tell KQML performative and the inform FIPA performatives is to convey to some receiving agent that the sending agent believes a particular proposition (contained in the content field of a performative) is true.
