Study of Performance Analysis in Wired and Wireless Network

Abstract

Problem statement:The main intent of this study is to derive a high performance clientserver network using hub, switch, Bluetooth, WI-Fi and Wimax using the steadfast algorithms. Approach: This study mainly focuses on M/M (a,b)/1 markovian model with adaboost algorithm and user selection algorithms to find performance on wired and wireless technologies in terms of service rate, arrival rate, Expected waiting time and Busy period. When comparing the wireless technologies with wired technologies in term of inter-arrival and inter-service time it has been found that the wireless technologies are better. Adaboost algorithm in between client-server is to deliver the data packets to the destination without any loss and also to boost the data packets to the destination when there occurs congestion in network. The main intention of user selection algorithm is to select the appropriate user one who have highest priority in the queue. If more than one user has the highest priority then a user is selected at random from among them with uniform probability. It also have been found that, in wireless technologies the data transaction in between client-server using Wimax technology is very efficient in M/M (a,b)/1 for implementation with adaboost and user selection algorithm in terms of arrival rate, service rate, Expected waiting time and Busy period implementation. Results: The values obtained from the bluetooth technology can use for calculating the performance of other wireless technologies. Conclusion/Recommendation: In order to provide security for the data packets which flows inside the network, we use RSA algorithm which gives elevated security measures.

Investigation of Empirical Wave Propagation Models in Precision Agriculture

“…The PE model computes the path loss of a traveling wave based on the antenna heights of transmitter and receiver that may present the plane earth reflection of the transmitted signal into the receiver antenna [9]; Path loss can be calculated by equation 2.…”

“…The large scale broadcast models is not completely appropriate where the detraction, reflection, and scattering properly disturb the communication channel and affects widely of the received signal as within practical tasks. However, PE formula in (2) can be adopted to provide early assessment of what to be predicted [9].…”

Performance evaluation of campus network involving VLAN and broadband multimedia wireless networks using OPNET modeler

“…The wireless communication systems inside a small area, for example, an office building, university's campus, or house are called WLAN [21]- [24]. The speed of transferred data in WLANs is less than that speed using wires, but WLAN has some advantages over wires [25], [26]. WLAN permits portable devices such as cellphones and laptops to move through a building and communicate with other devices in the LAN through a wireless network to transfer data, without the need for wires [27].…”

Performance Evaluation of Wireless Sensor Network Channel in Agricultural Application

“…WSN technology: There are two standard technologies are available for WSN: ZigBee and Bluetooth. They are operating at 2.4 GHz of the Industrial Scientific and Medical (ISM) license free band, huge spectrum allocation and worldwide compatibility (Kirubanand and Palaniammal, 2011;Patel et al, 2006). Table 1 shows the main features of Bluetooth and Zigbee technologies.…”
