Report on the Wireless Personal Area Network (WPANs)

Abstract of the Wireless Personal Area Network (WPANs)

The aim of the new generation of the Wireless Personal Area Network (WPANs) is to develop a highly rated data with consideration of several hundred Mb/s. The working of WPANs is based on the Ultrawideband (UWB) technology that works by having decisions taken for low power emission in the spectrum by the Federal communication commission (FCC). The spectrum of power emission ranges from 3 to 10 GHz. In case of direct sequence proposals of spectrum for the IEEE 802.15.3a is the Task Group (TG) that is directly connected to the proposal of Multi-Band OFDM Alliance (MBOA). On contrary to previously existing techniques and technologies the approach used in MBOA provide an additional new Physical Layer (PHY). The working principle is associated with the decentralized medium access control (MAC) protocol that is different on a working basis from IEEE 802.15.3 MAC. In the present research, the technical description and insights of MBOA, PHY layer, IEEE 802.15.3 and MAC is carried out by the means of simulation of performance.

I.   INTRODUCTION of the Wireless Personal Area Network (WPANs)

One of the ubiquitous technologies is the wireless personal area network (WPANs), for

instance, Bluetooth, standardized IEEE WPAN working group (WG) 802.1.5 that is a low-cost combination and new class of wireless applications. The WPANs have a number of applications in the network industry due to low-cost services, customer satisfaction, and availability of the services. Another type of WPANs is Universal Serial Bus (USB) that is dominating the standard for the wired but short-range connections. In these applications, USB provides maximum throughput that is increased from 12 Mb/s to 480 Mb/s and it is a cheap service available in the market. To combine the work, it is important to consider the consumer electronics multimedia system and the PC peripherals. The other features of Bluetooth devices are the Multi-Band OFDM Alliance (MBOA). To obtain a seamlessly integrated devices, MBOA Medium Access Control (MAC) support is used for the Quality of Service (QoS). The means are isochronous that support the need of wireless IEEE 1394 with the asynchronous data streams [1].

The setup of IEEE S02 .15.3 MAC is mainly dependent on the central coordination and work in the highly dynamic working conditions. In the working process, different and frequent topology changes are used to check the switching power of devices.

The aim of present work is to contribute to the development of the key features of MBOA and MAC with specifications. The paper considers different factors include an overview of MBOA PHY technology, MBOA MAC technology, and simulation of the topologies [2].

II.   High Speed WPAN PHY of the Wireless Personal Area Network (WPANs)

MBOA Physical Layer (PHY) uses the orthogonal frequency division multiplexing (OFDM). The combination of the latest technology is dependent on the band hopping, frequency wide bands of 528MHz with the forms of technology on the power basis. The basis at the point is next generation high-speed WPANs. The design of MBOA PHY is to fabricate to achieve data of up to 480 Mb/s. The frequency range is between 3168 MHz and 10560 MHz with the defined five-band groups. The frequency band is MBOA with 528 MHz and it is further divided into the 128 OFDM subcarriers from the whole number of bands as 122 with the pilot subcarriers. The WPANs have a number of applications in the network industry due to low-cost services, customer satisfaction, and availability of the services. To obtain a seamlessly integrated devices, MBOA Medium Access Control (MAC) support is used for the Quality of Service (QoS).

 The system is further categorized in seven Time Frequency Codes (TFC) with one of the common conjunctions. The Robustness is further increased with interleaving with the blocks of six OFDM symbols [3].

III.    Next generation WPAN MAC of the Wireless Personal Area Network (WPANs)

The 0.72 version of new MBOA MAC layer is designed for the high-speed, low network, and short range communication infrastructure. The support for QoS faces crucial feature with eight traffic classes that enable the prioritization [4].

The classes mapped for the four Access categories in MBOA WPANs with the arbitrary length of packets. The efficiency of the TDMA based system increase with the introduction of Prioritized Channel Access (PCA) along with the Distributed Reservation Protocol (DRP). The Enhanced Distributed Channel Access (EDCA) reserve the collision-free access for the channel. In the physical device system, the priority inside devices is to transmit the data packets [5].

The initial value and duration of the counter determine the slot for the transmission of data packets. In case of a failed transmission, the device introduces CW that reduce the probability of collision in the selected devices. The transmission opportunity of data is dependent on the PCA and DRP with the duration of frame exchange that is bounded with the TXOP limit. When accessing the new devices, the medium of PCA is required to be considered for the previously existing reservation. The limitation in data exchange is due solely due to transmitting devices [4].

a  Acknowledgement policies

There are three different types of acknowledgement policies used in MBOA and these policies are known as No-ACK, Immediate ACK, and Burst ACK.

b.      Minimum interframe space and aggregation

The burst ACK policy is defined for the transmission of data and it enhances the efficiency of applying minimum interface space (MIFS). The interface is between the connected and consecutive frames. The aggregated stream is subjected to maximum size with the data frame payload. The bad channel conditions are used to reduce the Packet Error Ratio (PER) that is further split in MSDU into the maximum of the eight fragments [5].

IV.  Simulation analysis  of the Wireless Personal Area Network (WPANs)

The results of the analysis are further compared to the stochastic simulation that can analyze the efficiency of MBOA and MAC layer. The simulation was performed with MBOA Orthogonal Frequency Division Multiplexing (OFDM) Physical Layer (PHY). To obtain a seamlessly integrated devices, MBOA Medium Access Control (MAC) support is used for the Quality of Service (QoS). The complementary Cumulative distribution function (CDF) result in all the stochastic data with the discrete Limited relative error (LRE). The local correlation is used to measure the accuracy of empirical estimation of results [6].

V.  Conclusion of the Wireless Personal Area Network (WPANs)

Summing up all the discussion from above, it is concluded that wireless communication system is expanding. Due to this there is need of ultra-band wireless band. Through this system it will become easy to transfer the data from one end to the other one. This report is giving some important information related to wireless communication in ultra-band network. The WPANs have a number of applications in the network industry due to low-cost services, customer satisfaction, and availability of the services.

To combine the work, it is important to consider the consumer electronics multimedia system and the PC peripherals. The setup of IEEE S02 .15.3 MAC is mainly dependent on the central coordination and work in the highly dynamic working conditions. The combination of the latest technology is dependent on the band hopping, frequency wide bands of 528MHz with the forms of technology on the power basis.
