Game-theoretic control is a promising new approach for distributed resource allocation. In this paper, we describe how game-theoretic can be viewed as having an intrinsic layered architecture, which provides modularization that simplifies the design. We illustrate architectural view by presenting details about one particular instantiation using potential games interface. This example serves to highlight strengths and limitations of proposed architecture while also illustrating relationship...

We consider the problem of designing distribution rules to share “welfare” (cost or revenue) among individually strategic agents. There are many known that guarantee existence a (pure) Nash equilibrium in this setting, e.g., Shapley value and its weighted variants; however, characterization space guarantees is unknown. Our work provides an exact for specific class scalable separable games includes variety applications such as facility location, routing, network formation, coverage games....

Traditionally, research focusing on the design of routing and staffing policies for service systems has modeled servers as having fixed (possibly heterogeneous) rates. However, are generally staffed by people. Furthermore, people respond to workload incentives; that is, how hard a person works can depend both much work there is divided between responsible it. In system, control such so rate will be impacted system’s policies. This observation consequences when modeling system performance,...

This paper seeks to bridge the gap between theory and practice of real-time scheduling in domain high speed multimedia networking. We show that strict preemptive nature leads more context switching, requires system calls for concurrency control. present our scheme called rate-monotonic with delayed preemption ( rmdp ) how it reduces both these overheads. then develop analytical framework analyze other schemes lie region (immediate) no preemption. Our idealized scheduler simulation...

Layered multicast is a promising technique for broadcasting adaptive-quality TV video to heterogeneous receivers. While several-layered approaches have been proposed, prior work has identified several problems including significant and persistent instability in quality, arbitrary unfairness with other sessions, low access link utilization due conservative bandwidth allocation, receiver synchronization. In this paper we propose new layered scheme, where exploit simple, coarse-grained,...

Two important requirements for protocol implementations to be able provide quality of service (QoS) guarantees within the endsystem are: (1) efficient processor scheduling application and processing (2) mechanisms data movement. Scheduling is needed guarantee that tasks involved in each stream execute a timely manner obtain their required share CPU. We have designed implemented an operating system (OS) mechanism called real-time upcall (RTU) such applications. The RTU provides simple...

In “Behavior-Aware Queueing: The Finite-Buffer Setting with Many Strategic Servers,” Zhong, Gopalakrishnan, and Ward develop a game-theoretic many-server Markovian queueing model finite or infinite buffers to study the behavior of strategic servers whose choice work speed depends on managerial decisions regarding (i) how many staff much pay them (ii) whether when turn away customers. order predictably control system performance (e.g., lost demand, customer wait times, server burnout, etc.),...

Packet telephony is of increasing interest in both the telecommunications and Internet communities. The emergence packet will create new services, presents an opportunity to rethink how conventional services are implemented. In this paper, we present architecture for over networks (TOPS). TOPS allows users move between terminals or use mobile while being reachable by same name. can have multiple control calls routed them. with a range capabilities such as support video, whiteboard, other...

With the increase in adoption of Electric Vehicles (EVs), proper utilization charging infrastructure is an emerging challenge for service providers. Overstaying EV after a event key contributor to low utilization. Since overstaying easily detectable by monitoring power drawn from charger, managing this problem primarily involves designing appropriate "penalty" during period. Higher penalties do discourage overstaying; however, due uncertainty parking duration, less people would find such...

This paper presents asymptotic properties of the Erlang-C formula in a spectrum many-server limiting regimes. Specifically, we address an important gap literature regarding its value critically loaded regimes by studying extensions well-known square-root safety staffing rule used Quality-and-Efficiency-Driven (QED) regime.
