Class-dependent linear holding and rejection cost rates are used to model differing levels of tolerance to delay and loss. Time is slotted, and the controller's backlog information is delayed by one slot. The goal is to design well-grounded and tractable scheduling policies that nearly minimize expected total discounted or long-run average cost. New dynamic index policies are introduced, awarding higher priority to classes with larger index values, where a class' index measures the marginal productivity of work at its current state. The results are obtained by deploying the work-cost analysis approach to marginal productivity indices (MPIs) for restless bandits developed by the author. The results of a computational study on two-class instances are reported, shedding light on how the MPI policy's relative performance varies with each parameter. Across the range of instances explored, the MPI policy is shown to be nearly optimal, and to substantially outperform conventional benchmark policies.","PeriodicalId":207883,"journal":{"name":"2007 Next Generation Internet Networks","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127042187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several standards organizations are designing next generation wireless network architectures with a suite of new network elements and protocols that provide service continuity for intra-and inter-provider roaming. However, each of these mobility solutions provides its own set of signaling mechanisms and methods of interaction with different functional network elements. Thus, it becomes a challenging task for the network operators and service providers to support roaming to the visited networks with diverse capabilities while supporting service continuity. In this paper, we first highlight some of the next generation standards and then describe the main functional components of a generic next generation wireless architecture as described in several evolving standards. We then focus on the operational usage of network layer mobility protocols such as Client Mobile IP, Proxy Mobile IP and application layer mobility protocol for next generation networks, and address the operational issues associated with roaming and service continuity. Finally, we propose comprehensive mobility solutions that support the heterogeneity associated with the intra-and inter-provider roaming.","PeriodicalId":207883,"journal":{"name":"2007 Next Generation Internet Networks","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133626244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Indeed, VCG auctions are known to both be efficient and produce proper incentives. In this note, we argue that, in fact, VCG auctions can hardly be applied to those problems, for different reasons depending on the model studied: 1. If some resource constraints (bandwidth, spectrum, and/or power) have to be taken into account, then computing allocations and prices implies solving optimization problems that are computationally hard for general network topologies. 2. If there are no such resource constraints, then VCG auctions, even if verifying many important and satisfactory properties, cannot verify a major one that is budget balance: the sum of subsidies given to relay nodes exceeds the sum of charges paid by traffic senders. This means that the auction regulator is required to continuously inject money to make the scheme work, which is unlikely to happen. In a second step, we discuss the combinations of properties that can be verified together, and prioritize them for finding out a proper pricing scheme.","PeriodicalId":207883,"journal":{"name":"2007 Next Generation Internet Networks","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114509233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
