“…En la Figura 2 se puede observar una simulación por computadora de las áreas de cobertura en la frecuencia de 2.4 GHz. También en la Figura 2 se puede observar una simulación por computadora de las áreas de cobertura en la frecuencia de 5 GHz; la única diferencia es una leve disminución en la amplitud de la señal (Sarddar et al, 2010). Posteriormente al estudio se llegó a la cifra de 385 AP para satisfacer las necesidades de la institución.…”

El proyecto "Aseguramiento de la conectividad de la red inalámbrica y calidad en el acceso al servicio de internet", contempla el desarrollo de una solución a las necesidades de conectividad WiFi en la Universidad Francisco Gavidia. La UFG a partir del año 2008 instaló la primera infraestructura que permitió ofrecer el servicio de internet inalámbrico en su campus. Sin embargo, se tuvo que superar grandes desafíos para ofrecer un servicio que permita abarcar el mayor número de usuarios con un nivel aceptable de servicio y que contara con medidas de seguridad apropiadas para una institución de educación superior.Palabras clave: Internet inalámbrico, gestión de la conectividad, arquitectura WLAN, autenticación de red, perfiles de usuario de red inalámbrica.

“…The undirected Neighbor Graph (NG), whose every edge states a versatility path between APs and the neighbor of edge states the set of potential APs. The scheme proposed in [7] utilized the neighbor graph and sweep the channels taking into account position, speed and direction of the station using this technique and is used to get the data about neighbor AP. The station checks just those channels which are chosen by the neighbor graph.…”

WLANs play a vital role in 4 th Generation (4G) cellular system due to its adaptability and mobility. The most important issue in wireless communication networks to provide seamless handoff. Handoff delay make of serious problem as a lot of research has been done in last few years to reduce the handoff delay incurred in the different level of wireless communication. The whole delay time of a handoff process is isolated into authentication , probe and re association delay time. So this paper reviews the brief description about the distinct handoff techniques used in wireless networks and analyze their merits and demerits. Some future research ideas are also suggested here.

“…The delay sometimes reaches 90% of the total switching time which ultimately leads to high packet loss and breaking of connection. Recently, researchers developed different schemes to take care of the existing problems and challenges in handoff in WSNs [3, 4]. Most of the schemes use other parameters such as bandwidth and data rate for handoff.…”

The IEEE 802.15.4 standard is a rapidly growing technology for short-range communications and low rate Wireless personal area networking. The standard has been widely accepted as the de facto standard for wireless sensor network (WSN) because of its low cost deployment and remarkable applications. The mobility management in the existing WSN has highly suffered from different issues like high packet loss and delay because the current mobility management in IEEE 802.15.4 lacks the support of handover management for real-time streaming applications. In this paper, we propose a new fast handoff mechanism which eradicates the scanning delay. The proposed scheme uses the information of link quality (LQ) of the neighboring coordinators (COs), and on the basis of this information it selects an appropriate CO for handoff. The proposed scheme is evaluated through extensive simulations which show its strength and accuracy in the context of switching of high streaming data from one CO to another.
