Abstract To fulfill various enhanced requirements of next generation wireless access, 5 G cellular network will drive towards higher energy efficiency, lower latency and higher reliable wireless networks. The key contributions can summarize as follows: (1) proposes frame-based max-weight scheduling (FMWS) with reconfiguration delay in combination of round–robin algorithm can dynamically control throughput and delay. The frame-based dynamic control (FBDC) policy is applicable to 5 G cellular network control systems in data link layer, provides a new framework for developing throughput-optimal network control policies using state-action frequencies. (2) proposes a novel approach in MAC layer--Virtual multichannels Parallelism Carrier Sense Multiple Access (VMCP-CSMA) which can compute a set of TDDM schedules for multiple channels at once rather than computing one schedule at a time and constantly switching or recomputing schedules. (3) proposes a novel criticality aware scheduler prioritization in VMCP-CSMA policy can reorder a set of TDDM schedules based on max-weight scheduling with reconfiguration delay according to different application requirements. It can achieve high throughput and low delay with low complexity compared with other schedulings.

Wireless Communication Network

ZigBee is a kind of new wireless communication technology which is widely used in many fields. It is now widely recognized that ZigBee is suitable for short distance, low complexity, low power, consumption and low rate applications. One of the most important applications is embedded system. Standards of the physical layer and the data link layer are developed by the group of IEEE802.15.4 and the others are developed by ZigBee alliance. First of all, the paper introduces the application of ZigBee wireless communication network. Then the emphases are to build ZigBee wireless communication network and take advantage of Visual Basic to realize RSSI collection.

Due to the classification of technologies in NASA’s and ESA’s technology readiness levels, newly developed components have to be space proven before they can be utilized in space missions. This space prove can be adduced by sending these technologies to orbit either as experiment on a piggyback flight or a dedicated mission. Over the last years the size of technologies and satellites has shifted to much smaller sizes. In this paper, the possibility of industrial verification of MEMS (Micro Electro Mechanical System) applications using dedicated pico-satellite missions is examined. Based on the CubeSat concept, a technology verification platform can be realized for verification of not only pico-satellite components, but also of components of complex systems and missions. Therefore a platform fulfilling the requirements for such industrial verification of components named MOVE (Munich Orbital Verification Experiment) is developed at the Institute of Astronautics (LRT). This platform enables professional verification of MEMS technology and techniques at overall mission costs of less than 100k€. As a first application of this approach, a mission called π-MOVE (π for piezo) will verify piezo motors on the developed platform. These piezo motors are representative for components of complex systems, as this motor concept is considered to be key technology for future segmented mirror telescope missions. In the mission design process for this platform, strong emphasis is put on the robustness of the design, low complexity and realizability within the institute’s environment. The advantages through access to both university and industry resources will be taken. The feasibility of professional technology verification is highly dependent on the test plans, which are developed in cooperation with the experienced industrial partners.
