Automated Negotiation Between Publishers and Consumers of Grid Notifications

Abstract

Notification services mediate between information publishers and consumers that wish to subscribe to periodic updates. In many cases, however, there is a mismatch between the dissemination of these updates and the delivery preferences of the consumer, often in terms of frequency of delivery, quality, etc. In this paper, we present an automated negotiation engine that identifies mutually acceptable terms; we study its performance, and discuss its application to a Grid notification service. We also demonstrate how the negotiation engine enables users to control the Quality of Service levels they require.

Grid Commerce, Market-Driven G-Negotiation, and Grid Resource Management

“…For instance, although both Kasbah and NDF model the devaluation of goods with time using time-dependent NDFs, they were primarily designed for bilateral negotiations and did not take into consideration the influence of market factors. While there are some (but very few) works on building Grid-negotiation agents [10], [16], [17], most of these research efforts are preliminary, and both considering market dynamics and making tradeoff decisions are not among their research focuses (see Section V). The goal of this research is to show that market-driven agents (MDAs) (Section II) previously engineered for e-negotiation are appropriate tools for G-negotiation because they possess many desirable properties (see Section II-A) such as being able to negotiate optimally and make tradeoff decisions.…”

“…In addition to economic models in [3], [7], and [8], there are also research initiatives (albeit, very few and very new) adopting negotiation models for Grid resource allocations [10], [16], [17] (see [41] for a survey). Preliminary work in this area aims to either integrate methods of negotiation [10] or adapt the negotiation mechanism by selecting from a range of methods [16].…”

“…Additionally, Lawley et al [17] investigated the use of negotiation agents for identifying the mutually acceptable terms among information publishers (providers) and consumers of message notification services in a Grid computing environment. Adopting NDFs in [22], the agents in [17] negotiate on terms such as frequency, format, and accuracy of information being delivered by the notification service.…”

“…Adopting NDFs in [22], the agents in [17] negotiate on terms such as frequency, format, and accuracy of information being delivered by the notification service. Empirical results in [17] seem to suggest that through negotiation, an information publisher can balance between the utility (satisfaction) of the consumers and its workload. Although in some cases, consumers' utility may be lowered (e.g., receiving less frequent message updates), lowering its workload (e.g., sending message updates less frequently) allows a publisher to benefit from serving more consumers.…”

Economics-inspired decentralized control approach for adaptive grid services and applications
