Cross Layer Design of Wireless LAN for Telemedicine Application

Abstract

Telemedicine system requires an acceptable network quality of service and cost. IEEE 802.11 wireless LAN technology has been developed to provide scalable and low cost network. For telemedicine applications however, the technology does not fulfil the quality of service requirement yet. In order to overcome this problem, a new cross layer design of wireless LAN is proposed.The design is based on IEEE 802.11g standard with modification in datalink and physical layer. This has been implemented in NS2 simulation environment. The simulation has been performed to deliver the video data for telemedicine application. Simulation result shows that the new cross layer design has better network quality of service for PSNR (Peak Signal Noise Ratio) and delay values than the conventional wireless LAN. Thus, the new design has a potential to be used in telemedicine system.

Consideraciones Metodológicas Y De Diseño Para Las Especialidades De Telemedicina en El Hospital De Tauramena

“…El desarrollo de ciertos trabajos se ha basado en la optimización de redes existentes mediante la aplicación de diseños de arquitecturas alternas a las usadas actualmente, como las arquitecturas por capas (Putra, Supriyanto , 2009;Singh, Rahman, Tapan, Abu y Bashar, 2012), mientras que otros se han basado en la integración de redes existentes de telemedicina con nuevas tecnologías, para garantizar y mejorar la calidad de los servicios de telemedicina (Qiao, 2005;Husni, 2006). En ambos tipos de trabajos se han empleado herramientas de simulación de redes para evaluar el desempeño de los nuevos modelos de telemedicina.…”

Implementation of Media Interactive Learning Based Wlan Technology (Study at SMK Kampar)

“…Putra [12], Soyinka [13], and Sugesti [14] have encountered that WLAN has superior characteristics compared to other wireless standards, mobility, high data rate, easy to implement and low cost.…”
