The Mobile Cloud Network is an emerging cost and capacity heterogeneous distributed cloud topological paradigm that aims to remedy the application performance constraints imposed by centralised cloud infrastructures. A centralised cloud infrastructure and the adjoining Telecom network will struggle to accommodate the exploding amount of traffic generated by forthcoming highly interactive applications...
The present paper deals with the path planning of a mobile object and optimisation of the locally generated safe path. It proposes a trajectory generation algorithm using fuzzy logic controllers in both directions propagation and obstacles avoidance. Associated with a workspace modelling, the algorithm tries to obtain a quasi-optimal global safe path for an autonomous mobile object which has to move...
The European Electronic Toll Service (EETS) allows different possibilities for the overall system design of interoperable toll systems. We study the effect of the overall system design on the operational costs using a model based, holistic, executable specification. The model is set up to give an accurate description of the interdependences as seen in the German toll system. Two different scenarios...
Mobile platforms have the resource-constrained characteristic, demanding to optimize the program to make up for the relative lack of resources. In this paper, using Symbian C++ as the development language, mainly optimize the code side and display side for the Symbian platform applications. Experimental results show that the technique improves efficiency and user experience degree.
Based on illuminating the structure, working principle and force analysis of mobile electron radar, the finite element analysis of sheet metal shell is carried out on ANSYS Workbench (AWE) platform. First, the structure of sheet metal shell is simplified, then the 3D entity model and meshing model of sheet metal parts both are established. Secondly, the material attribute, contact type, load and constraints...
In this paper we are given concept of our WiMAX (Worldwide Interoperability for Microwave Access) network performance for QoS monitoring and optimization solution for BS (Base Station) with multimedia application. In the communication sector, the optimal objective is to equate quality and cost. Due to its large coverage area, low cost of deployment and high speed data rates. WiMAX is a promising technology...
Mobile bridges are primarily to make span-crossing and form traffic path flexibly and rapidly. FRP (Fiber-reinforced polymer composite) is suitable for the construction of mobile bridge as its advantages of light-weight and high-strength. In this paper, the ANSYS optimization module is used to optimize the linear of the FRP bridge, in order to lose the weight of the bridge.
We propose an optimization-based framework to minimize the energy consumption in a sensor network when using an indoor localization system based on the combination of received signal strength (RSS) and pedestrian dead reckoning (PDR). The objective is to find the RSS localization frequency and the number of RSS measurements used at each localization round that jointly minimize the total consumed energy,...
With the improvement of living standards, shopping malls are bigger after constructing with more abundant goods and more variety of wares. Therefore, building a simple, fast and convenient shopping guide system has become a mutual concern of merchants and customers. In view of the mobile phone has become a popular consumer products, a simple optimization method was given to design shopping guide system...
The Evolved Packet Core (EPC), defined by 3GPP, provides the possibility of integrating 3GPP as well as non-3GPP access network technologies. This opens up new options for mobility through the use of inter system handover over several access network technologies. This paper provides an overview of the introduced component Access Network Discovery and Selection Function (ANDSF) from the 3GPP as well...
This work studies the dynamic transient stability of a 2-link wheeled-suspended mobile flexible manipulator. The dynamic transient stability criterion is constructed based on the reacting forces and skidding resistance forces existing between the tires and the road surface. At last, Computation simulation results are presented to illustrate the study. This criterion is feasible to evaluate the transient...
White space means spatially (or temporally) unused spectrum and this can be used on a unlicense basis. Since protecting primary users from harmful interference is the most important issue in unlicensed spectrum access on a secondary basis, regulatory authorities mandate the use of geolocation and DB (database) access capability as interference avoid scheme. The main role of this white space DB is...
The handling of the radio channel is an important aspect that determines the working capability of a mobile communication system. Since the channel behavior is influenced by the environment, which leads to a different behavior in different environments, the antenna design (synthesis) becomes environment dependent (time-variant) as well. In this paper, a capacity maximizing approach for the design...

This antenna feed has been designed for X-band frequencies widely used in terrestrial microwave communication for mobile & wireless applications. Simulated &...
Since mobile devices are equipped with limited battery power, it is essential to have efficient power management mechanisms in mobile broadband networks such as mobile WiMAX that enable always on connectivity and provide high throughputs. In recent times Voice over IP (VoIP) has emerged as an important and dominant application in broadband mobile networks such as WiMAX. VoIP traffic is uniquely characterized...

We study the mobile association problem: we determine the cells corresponding to each base station, i.e, the locations at which intelligent mobile terminals prefer to connect to a given base station rather than to others. This paper proposes a new approach based on optimal transport theory to characterize the solution based on previous works on fluid approximations. We characterize the optimal solution...
WiMAX is a promising solution for last-mile broadband Internet access. 802.16m is a new IEEE standard featuring multi-carrier technology to meet the requirement of IMT-Advanced for next generation mobile WiMAX. The design goal of IEEE 802.16m is to achieve 1Gbps over-the-air data rate with the help of multi-carrier operation. However, multi-carrier operation brings many challenges. In this paper,...
This paper describes new algorithms for mobile backbone network optimization. In this hierarchical communication framework, mobile backbone nodes (MBNs) are deployed to provide communication support for regular nodes (RNs). While previous work has assumed that MBNs are unconstrained in position, this work models constraints in MBN location. This paper develops an exact technique for maximizing the...
