Task distribution is affected by a negotiation process, a discussion carried on between nodes with tasks to be executed and nodes that may be able to execute those tasks. In contract net protocol, once negotiation successes, the task execution is assumed to success. However, in real world, even though a task is awarded to successfully bidding nodes, it may be delayed. Such delay may badly propagate in whole system. Here, we introduce real-time constraints into contract net protocol to manage task execution for avoiding the task's delay, or even though being delayed, the failure cannot propagate to whole system. In this paper, we first present a real-time contract net protocol which is an extension of contract net protocol with real-time constraints for distributed computing. Our proposition extends the basic negotiation protocol to negotiation and controlling execution of task. The controlling process is based on task deadline time we also present an extension of the internode language of contract net protocol specification with real-time constraints Springer, 1996 real-time nationallicence time-out nationallicence coordination model nationallicence contract net protocol nationallicence time delay nationallicence Qiaoyun Li Department of Computer Science, Wuhan University, 430072, Wuhan, China aut Jiandong Li Department of Computer Science, Wuhan University, 430072, Wuhan, China aut Dawei Dai Department of Computer Science, Wuhan University, 430072, Wuhan, China aut Lishan Kang National Key Software Engineering Laboratory, Wuhan University, Wuhan, China aut Wuhan University Journal of Natural Sciences Wuhan University 1/2(1996-06-01), 156-162 1007-1202 1:2<156 1996 1 11859 https://doi.org/10.1007/BF02901219 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1007/BF02901219 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Qiaoyun Li Department of Computer Science, Wuhan University, 430072, Wuhan, China aut NATIONALLICENCE 700 1- Jiandong Li Department of Computer Science, Wuhan University, 430072, Wuhan, China aut NATIONALLICENCE 700 1- Dawei Dai Department of Computer Science, Wuhan University, 430072, Wuhan, China aut NATIONALLICENCE 700 1- Lishan Kang National Key Software Engineering Laboratory, Wuhan University, Wuhan, China aut NATIONALLICENCE 773 0- Wuhan University Journal of Natural Sciences Wuhan University 1/2(1996-06-01), 156-162 1007-1202 1:2<156 1996 1 11859 Metadata rights reserved Springer special CC-BY-NC licence nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-springer
