Due to the limitations of mobile devices in terms of processing power and battery lifetime, cloud based solutions offer an attractive approach to answer these shortcomings. Since offloading intensive computation tasks to an edge/cloud server would achieve impressive performances, computation offloading paradigm has attracted the focus of many research groups in the last few years. This paper considers...
In concert with advances of wireless technologies in facilitating internet connectivity of Internet of Things (IoT) devices, mobile edge computing can provision and distribute computing resources at the cloudlets to efficiently process a high volume of IoT data. Among the IoT applications, multi-party data sharing among IoT devices, wireless access nodes and cloudlets is becoming increasingly critical,...
Among the mobile applications contributing to the surging Internet traffic, video applications are some of the biggest contributors. Most of these video applications use HTTP/HTTPS tunneling making it difficult to apply port based or packet data based identification of flows. This makes it challenging for network operators to enforce bandwidth regulation policies for app based service differentiation...
Wireless rechargeable sensor networks (WRSNs) have become an important approach to solve the energy constraint problems in traditional battery-powered systems. In WRSNs, one or more mobile chargers (MCs) can traverse the network to transfer energy to sensor nodes. The key issue of MC is to find an optimal charging path. In this paper, we study security monitoring WRSNs for disaster area built from...
To address the challenge arising from mobile users' increasing demands for multimedia services, applying content caching in heterogeneous networks (HetNets) is regarded as an effective way to offload traffic and improve the capacity of mobile networks. In this paper, we aim at designing novel content caching strategies in HetNets to offload the network traffic and support users' requests locally....
With the fast growth of mobile data services, rich services deliver a brand new experience to end users, and also bring about new opportunities for operators. Some applications, such as vehicular and industrial applications, demand a level of reliability that wireless communication systems typically are not able to guarantee. This paper provides a framework that enables these applications to make...
In this paper, we study the joint computation offloading and resource allocation problem exploiting computing resources from both mobile edge cloud and mobile peers. Our design aims to optimize the computation load assignments to local processors in the mobile users, mobile peers and the edge cloud jointly with the resource allocation to achieve the minimum weighted energy consumption subject to practical...
Advancements in mobile communication technologies and the continuously increasingly diffusion of smartphones equipped with several physical and virtual sensors and with different network support are promoting novel mobile healthcare scenarios where patients with critical physical/behavioral conditions can be provided with anywhere and anytime care assistance even while on the move. In particular,...
Conventional mobile computation offloading relies on offline prefetching that fetches user-specific data to the cloud prior to computing. For computing depending on real-time inputs, the offline operation can result in fetching large volumes of redundant data over wireless channels and unnecessarily consumes mobile-transmission energy. To address this issue, we propose the novel technique of online...
IBM Research and Micro-System Technology and Solutions Team are enabling next generation computing systems with heterogeneous packaging integration that support both large size / high performance systems and also support miniaturized / low power mobile wireless systems / sensors.
The demand for indoor positioning and navigation is increasing exponentially in recent years. When more international students and visitors come to the university campus for study and academic activities, wireless indoor positioning and navigation by smartphones becomes a truly welcomed service. We propose a hybrid system by utilizing iBeacon within the Wi-Fi network with fingerprint technique, to...
Hybrid energy supply (HES) based wireless communication systems have recently emerged as a new paradigm to enable green networks, which are powered by both the traditional and harvested energies. In this paper, we propose a hybrid energy based communication scheme for 3-D wireless networks in a dense urban area. The proposed scheme is based on hybrid energy source, where harvested energy from ambient...

In this paper, we present an approach to ensure efficient energy distribution among all the nodes in a wireless sensor network by employing mobile chargers from several landmark locations within each sensor cluster with timing constraint. Mobile chargers are considered to use radio frequency signals for the charging purpose and use Hamiltonian cycle to ensure minimum time required to visit landmarks...
Optical wireless communication (OWC) is position sensitive and deemed not suitable for ultra-high throughput mobile communications. In this paper, we propose an optical mobile communication (OMC) system, which dynamically allocates optical beams to mobile users and tracks the users adaptively, thus extends OWC to mobile scenarios. Principles of OMC is introduced and several key design problems are...
A positioning system for underwater users is proposed based on the underwater wireless optical CDMA network. Two different localization schemes namely Received Signal Strength (RSS) and Time of Arrival (TOA) are discussed and their performances in the presence of optical turbulence are explored.
In this work, we consider the economics of the interaction between Mobile Virtual Network Operators (MVNOs) and Mobile Network Operators (MNOs). We investigate the incentives of an MNO for offering some of her resources to an MVNO instead of using the resources for her own. We formulate the problem as a sequential game. We consider a market with one MNO and one MVNO, and a continuum of undecided endusers...
As mobile data usage increases dramatically, new architectures and technologies for wireless communication are required. Next generation of mobile networks are expected to be augmented by a massive amount of small cells that will be densely deployed.
