In this paper, the joint optimization problem with energy efficiency and effective resource utilization is investigated for heterogeneous and distributed multi-core embedded systems. The system model is considered to be fully a heterogeneous model, that is, all nodes have different maximum speeds and power consumption levels from the perspective of hardware while they can employ different scheduling...
In this paper, we design provably-good algorithms for task allocation in multi-robot systems in the presence of payoff uncertainty. We consider a group of robots that has to perform a given set of tasks where each robot performs at most one task. The payoffs of the robots doing the tasks are assumed to be Gaussian random variables with known mean and variances. The total payoff of the robots is a...
We propose a spectrum utility based WiFi offloading scheme on the edge of cellular networks, implemented with non-orthogonal multiple access (NOMA) techniques. In our proposed scheme, we aim to optimize the spectrum utility, obtained by service providers, through power allocation and offloading ratio. With practical constructions of the cost functions on spectrum, we define the spectrum utility mathematically,...
We investigate the energy efficiency (EE) maximization problem under the scenario of Device-to-Device (D2D) communications underlaying cellular networks. By jointly considering time-varying channels and stochastic arrivals, we propose a distributed power allocation algorithm for both D2D user groups (DUGs) and cellular user terminals (CUTs) with long- term quality of service (QoS) provision. To effectively...

In this paper, by jointly considering power allocation and network selection, we maximize the energy efficiency in heterogeneous wireless networks (HetNets), where user equipments are typically multi-homed. In order to effectively deal with the dynamics of HetNets, a stochastic optimization problem is formulated, which optimizes the long-term energy efficiency under the constraints of system stability,...
The proliferation of smartphones has enabled a novel paradigm, participatory sensing, which leverages the smartphones to collect and share data about their surrounding environment. Since the sensing tasks are location-dependent and have time features, it is crucial and challenging to find a proper allocation of sensing tasks to ensure the timeliness of tasks and the quality of sensing data. In this...
This paper presents a novel auction-based structure to multi-robot coalition formation problem. The structure, which is called multi-robot Coalition Structure Generation based on Credit Mechanism (CoSGCrM), contains a sub-optimal coalition member selection algorithm with an analysis of its soundness and completeness. A credit mechanism is introduced to reduce the complexity for the coalition leader...
In heterogeneous wireless networks, it is common for service providers to employ multiple radio access technologies (RATs) to meet the requirements of the quality of services and as well to improve the system performance. In this paper, we propose an optimal resource allocation scheme for heterogeneous wireless networks by maximizing the users' quality of experience (QoE), which is a widely used subjective...
For resource coordination and management of large construction machinery in engineering projects, the revised dual node network was used to program the distribution and use of large machinery, and to design the distribution process of network planning. On the basis of rational multitasking allocation with network planning method, the target procedure was tracked and controlled to reach the goal of...
With the convergence of wired line Internet and mobile wireless networks as well as tremendous demand on video application in mobile wireless Internet, it's essential to design an effective video streaming protocol and an efficient resource allocation scheme for video delivery over wireless Internet. In this paper, we employ WMSTFP, an end-to-end TCP-friendly multimedia streaming protocol, to detect...
