ACM International Symposium on Mobile Ad Hoc Networking and Computing (MobiHoc) 2020 IEEE International Symposium on Modeling and Optimization in Mobile, Ad Hoc, and Wireless Networks (WiOpt) 2019 Submission and Publication Chair ACM SIGMETRICS 2021 Submission Deadline Saturday 30 Nov 2019 Proceedings indexed by : Conference Dates Jun 30, 2020 - Jul 3, 2020 Conference Address MobiHoc is a premier international symposium dedicated to addressing challenges in dynamic networks and computing. In this paper, we study a monopolistic provider who initially does not know users' demand and needs to learn it over time by observing the users' responses to the service prices. Our analysis uses a novel application of Heavy-Traffic theory under the assumption of vanishing caches to show that predictive caching fundamentally alters the asymptotic throughput-delay scaling. The acceptance rate is 15%. LLOCUS first estimates the power of the unknown transmitter and then scales the reported RSS values such that the unknown transmit power problem is transparent to the method of localization. To address it, we propose an online scheduling algorithm to decide the execution time window, the number and the type of concurrent workers and parameter servers for each job upon its arrival, with a goal of minimizing the weighted average completion time. Demo: Demo Session. It can be profitable for vehicle service providers to set service prices based on users' travel demand on different origin-destination pairs. The miner that comes up with the smallest hash value among all miners will win the block. The DANGER network is completely distributed, can work even partitioned or incase of drones failures. — PTS achieves high parallelism due to some novel designs.

With the production trace from Google Cluster, our experimental and large-scale simulation results indicate that O4A can increase the total utility by up to $39.42\%$ compared with state-of-the-art utility-agnostic methods. Our online algorithm consists of (i) an online scheduling framework that groups unprocessed ML training jobs into a batch iteratively, and (ii) a batch scheduling algorithm that configures each ML job to maximize the total weight of scheduled jobs in the current iteration. Ranked 1st over Electrical Engineering Class of 2011, Alexandria University. We carefully identify and tackle several challenges in learning and localizing, based on RSS, in such a dynamic environment. We design a pricing and vehicle supply policy, considering the tradeoff between exploration (i.e., learning the demand) and exploitation (i.e., maximizing the provider's short-term payoff). In this paper, we present a system that provides advanced analytic and visual capabilities with regard to the OP_RETURN operator. We model interactions among miners as a non-cooperative game and formulate a Nash equilibrium problem to investigate the effects of offloading on miners' utilities.
