In this paper, we propose An Android Behavior-Based Malware Detection Method using Machine Learning. We improve an Android application sandbox, Droidbox, by inserting a view-identification automatic trigger program which can click mobile applications in the meaningful order. Taking advantage of Droidbox result, we collect the behavior such as network activities, file read/write and permission as the...
The mobile social network (MSN) can be considered as a system which provides a variety of data delivery services involving the social relationship among mobile users. Mobile social networks have the surprising property of being "searchable": Ordinary users contact with each other more frequently when they have more social features in common. In this paper, we first define a priority relationship...
Personal mobile data are being extensively collected by various service providers, in the form of data stream. Most service providers promise their customers for not misusing their data by paper-based agreement. However, the customers have no way to know whether the agreements are strictly followed or not, unless any scandals of private data misuse are revealed. To guarantee the correct use of customers'...
One major problem of using location data collected from mobile cellular networks for mobility modelling is the oscillation phenomenon. An oscillation occurs when a mobile phone intermittently switches between cell towers instead of connecting to the nearest cell tower. For the purpose of mobility modeling, the location data needs to be cleansed to approximate the mobile device's actual location. However,...
Machine-to-machine (M2M) communication technologies have been rapidly developed in recent years to support different kinds of applications, such as automatic monitoring from user equipments (UEs) to home devices. Unfortunately, such applications introduce heavy traffic in both the radio access networks and core networks (CNs). 3rd generation partnership project (3GPP) has defined its local IP access...
In mobile sensor networks (MSNs), it is common for the base station to issue {\em data acquisition} queries requesting for data to be sensed from specific regions of the data space. Such kind of queries are especially important in MSNs for reconnaissance and disaster rescue applications. In this paper, we investigate how multiple data acquisition queries can be answered quickly in sparse mobile sensor...
We demonstrate a system that monitors the taxi availability at taxi stands by mining real-time taxi trajectory data streams. The system includes a server-side trajectory data stream processing and mining program and a client-side mobile application for Android smart phones. The server program continuously monitors for each taxi stand the numbers of taxis queueing at the taxi stand, the numbers of...
By analyzing architecture of existing Heterogeneous wireless networks, mapping wireless resource management to wireless measurement indexing, proposed an improved model of CAN multidimensional ADHOC. Simulation result showing improvement in connectivity, network maintenance cost etc.
This work demonstrates the first fabricated macro-level RRAM-based nonvolatile SRAM (nvSRAM) that use a new 8T2R (Rnv8T) cell to achieve fast NVM storage and low VDDmin read/write operations. The Rnv8T cell uses two fast-write low-current RRAM devices, 3D stacked over the 8T, to achieve low store energy with a compact cell area (1.6x that of a 6T cell). A 2T RRAM-switch provides both RRAM control...
Recently, next-generation digital entertainment and mobile communication devices are driving the demand for high-performance processing solutions. In order to achieve this demand, multiple-issue processors such as very long instruction word (VLIW) architecture augmented with a reconfigurable hardware accelerator have been proposed in many papers. The reconfigurable hardware accelerator is usually...
It is expected that Peer-to-Peer (P2P) services will co-exist with the client-server based services such as IMS. Mobile users may subscribe to the traditional wireless cellular services while participating in P2P overlay networks. In this paper, a method is proposed to reduce the signaling overhead in a mobile P2P system. With the help of the underlying infrastructure, a mobile device in the P2P overlay...
Because of the environment and the nature of the signal itself, GPS or wireless mobile positioning technology always has any unavoidable defect. But higher coverage percentage, reliability or precision than single positioning can be gained if integrating at least two positioning technologies' advantages and avoiding their deficiencies. So the developmental trend of mobile positioning technology is...
The scale of network and bandwidth of link have been limited by current routing technologies in hybrid wireless ad-hoc networks, so we present a new routing algorithm. In the routing algorithm, the routing information is treated as a resource, and it can be stored and searched in a distributed way with Chord. The routing of data packet prefers to forward by infrastructure. In comparison with OLSR,...
The processing of a Continuous Reverse k-Nearest-Neighbor (CRkNN) query on moving objects can be divided into two sub tasks: continuous filter, and continuous refinement. The algorithms for the two tasks can be completely independent. Existing CRkNN solutions employ Continuous k-Nearest-Neighbor (CkNN) queries for both continuous filter and continuous refinement. We analyze the CkNN based solution...
In this paper we propose a mobility model derived from real-time strategy gamepsilas replays which can reflect confrontation & collaboration characteristic of nodes movement in military scenario. This mobility model covers several unitspsila characters, including the velocity distribution, mutual synergies, creation/destruction and terrain effect. Game playerspsila human decision is also involved,...
In this paper, we present a design of PRMCS (Pharos remote monitoring and control system), and study the communication protocols based on WSN (wireless sensor network) for PRMCS. The PRMCS is the integrated pharos system, consisting of RTU (remote terminal unit), control center, and sensors. Two communication patterns based on WSN are used in PRMCS, one is used on the control center, the other on...
