“…For example, they concede slower when resources such as the bandwidth are scarce. Comuzzi et al [22] proposed a resource dependent negotiation strategy for pricing of network services. Similar to our approach, the negotiation strategy is time dependent, bilateral, and considers multiple criteria.…”

Cloud service level agreement negotiation is a process of joint decision-making between cloud clients and providers to resolve their conflicting objectives. With the advances of cloud technology, operations such as discovery, scaling, monitoring and decommissioning are accomplished automatically. Therefore, negotiation between cloud clients and providers can be a bottleneck if it is carried out manually. Our objective is to propose a state-of-the-art solution to automate the negotiation process for cloud environments and specifically infrastructure as a service category. The proposed negotiation strategy is based on a time-dependent tactic. For cloud providers, the strategy uniquely considers utilization of resources when generating new offers and automatically adjusts the tactic's parameters to concede more on the price of less utilized resources. In addition, while the previous negotiation strategies in literature trust offered quality of service values regardless of their dependability, our proposed strategy is capable of assessing reliability of offers received from cloud providers. Furthermore, to find the right configuration of the time-dependent tactic in cloud computing environments, we investigate the effect of modifying parameters such as initial offer value and deadline on negotiation outputs that include ratio of deals made, and inequality index. The proposed negotiation strategy is tested with different workloads and in diverse market conditions to show how the time-dependent tactic's settings can dynamically adapt to help cloud providers increase their profits.

“…As any user arrival or departure from the network requires a reallocation of resource/services (and, consequently, triggers a new auction), the auction-theoretic approach is suitable to applications with elastic QoS requirements. On this line, bilateral negotiation protocols [7], [8], [9] have been adopted to tackle the congestion problem [10], with the service provider negotiating (and possibly agreeing upon) the communication parameters with a customer only once, upon the latter arrival. As observed in [10], the underlying negotiation-theoretic assumption that the supplier and the customer utilities are linear in negotiation parameters [7] hampers the straightforward application of negotiation algorithms to a networking setting.…”

In this light, we propose a negotiation algorithm, based on [7], that can accommodate the nonlinear utilities of end-users and providers, for any number of negotiated attributes.…”

In this paper, we propose a new algorithm for bilateral multi-attribute negotiations between autonomous agents with nonlinear utilities and detail on its application for pricing the wireless access services. In particular, we consider a scenario in which a wireless service provider adapts its offer of wireless bandwidth to the dynamics of the access demand and of the available spectrum. To achieve this, the provider performs one-to-one negotiations with the customers over the service transmission rate and the service price. The proposed negotiation algorithm is a practical solution for pricing those customers that require constant-rate service. Numerical simulations provide in-depth illustration of the scheme performance for various network settings
