Although a large literature on delegation exists, few models have pushed beyond a core set of canonical assumptions. This approach may be justified on grounds of tractability, but the failure to grasp the significance of different assumptions and push beyond specific models has limited our understanding of the incentives for delegation. Consequently, the justifications for delegation that have ...

We introduce the idea of delegation in distributed tree-search, as a method to reduce the communication overhead when solving Distributed Constraint Satisfaction Problems (DisCSPs). With delegation, an agent can eliminate some direct forward links to child neighbours and choose intermediaries for communicating with such children. We present an algorithm which constructs long delegation paths au...

Security Policies (SP) constitute the core of communication networks protection infrastructures. It offers a set of rules allowing differentiating between legitimate actions and prohibited ones and consequently, associates each entity in the network with a set of permissions and privileges. Moreover, in today's technological society and to allow applications perpetuity, communication networks m...

This paper introduces a novel approach to distributed computing based on delegation-agents, and describes its applications to decentralize network management. Delegation agents are programs that can be dispatched to remote processes, dynamically linked and executed under local or remote control. Unlike scripted agents, delegation agent programs may be written in arbitrary languages, interpreted...

Credible delegation of discretion obtains when it is a rational strategy for managers not to overrule employee decisions that are based on delegated decision rights or renege on the level of delegated discretion (and this is common knowledge). Making delegation of discretion credible becomes a crucial issue when organizations want to sustain the advantages that may flow from delegation: Such ad...

Price delegation to the sales force is a practice widely adopted by firms. This paper examines the relationship between price delegation and managerial profits using a laboratory economics experiment. A novel feature of our experiment is that we study how varying the relationship organization of the sales manager and salesperson to allow for 1) requests by the salesperson for the manager to cho...

Delegation is one of the main determinants of coordination, joint activity and collaboration within the context of organizations. In particular, delegation is the fundamental aspect for the redistribution and for the transfer of tasks within the context of an organization, and it is responsible for making organizations dynamic. We present in this paper a conceptual and formal analysis of delega...

In grids, delegation is a key facility that can be used to authenticate and authorize requests on behalf of disconnected users. In current grid systems, delegation is either performed dynamically, in an unrestricted manner, or by a secure but static method. Unfortunately, the former compromises security and the latter cannot satisfy the requirements of dynamic grid application execution. Theref...

The radio frequency identification (RFID) protocols are vulnerable to various attacks from an active or passive adversary. We shed light upon some existing security flaws in these delegation protocols. It is useful to mitigate many security weaknesses in such delegation protocols to promote the acceptance of RFID tags. We propose that a scalable RFID delegation protocol will be against traceabi...

In this paper we give a classiication of delegation schemes into four main classes. To solve the problem with simply chained tokens in cascaded delegations we introduce the concept of hierarchical delegation tokens. To realize this concept we use the Schnorr signature scheme and self{certiied public keys introduced by Girault. We describe the rst approach for hierarchical key generation based o...
