The role and importance of wimax mobile system as a high-performance data transfer technology in wireless sensor networks for wide area monitoring applications

Abstract: The study discuses basic features and functional design of WiMAX Mobile system, based on the IEEE 802.16e (Release 1.5 Rev. 2.0) standard. The analysis has been made in terms of ability to use this system to transmit video stream related to monitoring of large agglomeration areas.
What is more, the study includes comparison of technical parameters of WiMAX Mobile system with competitive systems such as: HSPA+ and UMTS-LTE, which may be used for transmission of this type of data in the future. There has also been made an analysis of selected aspects of data security (in the system approach) connected with transmitting of image data by the WiMAX Mobile networks.
1. INTRODUCTION
Video monitoring systems are used to transmit and archive video streams associated with observation of various types of objects in selected geographic area.
In the study specially large attention will be dedicated to issue of transmitting this type of data by the metropolitan networks based on WiMAX Mobile system (Worldwide
Interoperability for Microwave Access). CCTV monitoring of cities creates extremely wide possibilities of crimes and offences detection as soon as the moment of its committing.
Studies which has been made on the issue clearly show that in areas of cities covered with monitoring, the number of assaults, theft or property devastation has been significantly decreased. In case of roads monitoring compliance with traffic rules increases.
Sensor networks can consist of many various types of sensors, for example: seismic, thermal, acoustic or equipped with video camera. Such variety of sensors types results with
their ability to perform their functions in various conditions and control many different factors. Wireless Sensor Networks (WSN) are increasingly used in so called intelligent transport. It is associated, most of all, with the process of traffic monitoring which is realized by transmission of video image gained, in individual nodes of network, to the central unit, where processing, analysis and if necessary archivization of the image is performed. What is more, current level of techniques allows automatic speed measurement of cars on the roads basing on the recorded video. (...)
