Automated Storage

The preconditions of storage pre-schedule and real-time schedule management are wireless access and mobility support technology in aluminum profile logistic, which is vital for the automated storage/retrieval system(AS/RS) and logistics processes, such as intelligent warehousing and shipment. Understandings characters of the current wireless access technologies, applicability of networking mobility schemes, and their cooperation or compatibility with the Internet of things, decide the AS/RS and logistics structure and its whole efficiency. So the relational technologies and schemes are introduced in this paper from bottom to top according to Open System Interconnect seven layers protocols. It reveals that integration of multi-technologies was widely adopted in project implementation, which can be helpful to achieve high quality of mobile Internet access with lesser costs. Moreover, the feasibility of handover simplification and quality of service construction imply the success of schemes in design. Finally the strategic impact factors of the networking mobility support technology for AS/RS and logistics are concluded as overlapping coverage network optimization, delay tolerant network, and quality of service system based on user behavior.

Important Design

The present chapter contains a thorough investigation of Quality of Service, Energy Conservation and mobility in 802.11 and 802.16 standards. Interest on these two technologies arises from the fact that they are designed to cooperate offering wireless access capabilities in Next Generation Networks (NGNs). Under NGN Wireless architectures, key challenges must be taken into account: (a) Broadband technologies are based on QoS Enabled Telecommunication Services; (b) Mobile devices are battery limited. In fact, how to prolong the life time of a mobile device and minimize power usage is a very important design issue; (c) Wireless operation means that the user is expected to roam freely, which must also be taken into account. The dependability of NGN operation is obviously depended on these three features.

The forthcoming wireless networks provide the continuous services to their users for different applications by the integration of diverse wireless access technologies known as heterogeneous wireless network. The heterogeneous wireless network improves the Quality of Service for stationary and non-stationary mobile users. Even when users are in mobility the services are provided by means of handoff or handover. In this paper, the integration of three different wireless networks such as LTE, WiMAX and Wi-Fi networks and their vertical handoff performance analysis are presented. These diverse wireless networks which are considered for integration are modeled as a heterogeneous wireless network. This network is designed using QualNet simulator. Furthermore, the designed heterogeneous network, vertical handoff performance is estimated by using factors such as throughput, jitter and End to End delay. With these performance factors, the designed network’s Quality of Service (QoS) is estimated under mobility conditions.

Micro Mobility

Provision of Quality of Service (QoS) and Micro Mobility management is imperative to delivering content seamlessly and efficiently to the next generation of IP based mobile networks. Micro mobility management ensures that during handover the disruption caused to the live sessions are kept to a minimum. On the other hand, QoS mechanisms ensure that during a session the required level of service is maintained. Though many micro mobility and QoS mechanisms have been proposed to solve their respective aspects of network operation, they often have interaction with each other and can lead towards network performance degradation. This chapter focuses specifically on the issues of interaction between micro mobility and QoS mechanisms. Special focus is given to the relatively unexplored area of the impact Mobility Agents can have on the wireless access network. Mobility Agents play a central role in providing micro mobility support. However, their presence (location and number) can affect the routing as well as the handover delay. Through an example network this issue is highlighted. Following which an optimization framework is proposed to deploy Mobility Agents optimally within a micro mobility enabled wireless access network to minimise both the routing overhead as well as the handover delay. Results show considerable improvements in comparison to deploying the Mobility Agents arbitrarily.

With the accelerated pace of life, the traditional ordering food has been unable to meet customers needs. The development of intelligent hand-held devices create the conditions for wireless ordering food. Confronted with the present needs, a hand-held ordering food system based on Android has been designed by the authors combined with the traditional ordering process. The system established two ordering models with Bluetooth and mobile Internet, and realized interaction between mobile terminal and server using J2EE and Android application development technology. The experiments show that the system completes all the process of ordering, and it has the advantages of strong mobility, convenient operation, full functions and so on, which can save money for the catering industry and improve the quality of service.
