The IEEE 802.16 WiMax standard provides a mechanism for creating multi-hop mesh, which can be deployed as a high speed wide-area wireless network. To realize the full potential of such high-speed IEEE 802.16 mesh networks, two efficient wireless radio resource allocation extensions were developed. The objective of this paper is to propose an efficient(More)
We propose a dynamic auction mechanism to solve the allocation problem of computation capacity in the environment of cloud computing. Truth-telling property holds when we apply a second-priced auction mechanism into the resource allocation problem. Thus, the cloud service provider (CSP) can assure reasonable profit and efficient allocation of its(More)
Machine-Type-Communications (MTC) applications are automated applications, which involve communications between machines or devices without human intervention. Such applications are widely adopted in our everyday life [1]. Though cellular mobile networks could offer MTC ubiquitous network access service with widely deployed infrastructure, they were(More)
Supporting user mobility is an important requirement in design and deployment of a wireless mesh network. This paper presents network level mechanisms for supporting seamless handoff of user between access points in the mesh network. Our goal is to minimize the packet loss incurred in the process of handoff. In realizing the goals, we propose two data(More)
We use a Bayesian game-theoretic approach to model transmission control in energy-harvesting wireless sensor networks. In general, the energy state of an energy-harvesting sensor varies more dramatically with time as compared to traditional battery-powered sensors. Therefore, each energyharvesting sensor is aware of its instantaneous energy state, which is(More)
In this paper, a distributed mechanism for application-aware proximity services (ProSe) in device to device (D2D) communications is presented. The method, which is derived from the bio-inspired firefly algorithm, can achieve proximity discovery and synchronization at one time. To be precise, this mechanism not only enables neighbour discovery and service(More)
