In this paper, we present a consensus algorithm for synchronous distributed systems using cooperating mobile agents. The algorithm is designed within a framework for mobile agent enabled distributed server groups (MADSG), where cooperating mobile agents are used to achieve coordination among the servers. Being autonomous and cooperative, cooperating mobile agents exchange information among them...

A left-forbidding grammar, introduced in this paper, is a context-free grammar, where a set of nonterminal symbols is attached to each context-free production. Such a production can rewrite a nonterminal provided that no symbol from the attached set occurs to the left of the rewritten nonterminal in the current sentential form. The present paper discusses cooperating distributed grammar systems...

It is important for intrusion detection systems (IDSs) to share information in order to discover attacks involving multiple sites. However, no framework exists for an IDS to request from and send to another IDS data relevant to specific events. The lack of such a framework may result in a waste of processing time, storage capacity and network bandwidth. This paper proposes a formal framework mo...

1 INTRODUCTION Artificial Intelligence (AI) techniques, and expert systems technology in particular, has often been used to tackle the most difficult automation problems. This is especially true in industrial applications where conventional software and teams of operators were unable to cope with the demands of rapidly changing, complex environments. After more than a decade of exploitation, hu...
