In this paper, an analytical model is developed for the performance study of an IEEE 802.11n wireless local area network (WLAN) supporting voice and video services, considering the new features of the medium access control (MAC) protocol proposed in IEEE 802.11n, i.e., frame aggregation and bidirectional transmission. We show that these enhanced MAC mechanisms can effectively improve the networ...

A wireless local area network (WLAN) is designed for an IC factory in Hong Kong using the hierarchical genetic algorithm (HGA). The HGA is capable of handling multiobjective functions and discrete constraints. Because of this uniqueness, together with the adopting of a Pareto ranking scheme, a solution can be reached even when skewed multiobjective functions and constraints confinements are bei...

A custom designed WLAN (Wireless Local Area Network) based sensor interface is presented in this paper. It is aimed at wirelessly interfacing a large variety of sensors to supplement built-in sensors in smart phones and media players. The target application area is collection of human related motions and condition to be applied in musical applications. The interface is based on commercially ava...

The rapid progress of wireless communications and the availability of lightweight, smallsize, and portable computing devices have given great impacts on our communities. These technologies have made the dream of communications at anytime and at anywhere come true. A common solution for such ubiquitous communications is the use of the wireless local area network (WLAN). WLAN has been widely stud...

In this paper, the packet error rate (PER) of IEEE 802.15.4 low rate wireless personal area network (WPAN) under the interference of IEEE 802.11b wireless local area network (WLAN) is analyzed. The PER is obtained from the bit error rate (BER) and the collision time. The BER is obtained from signal to noise and interference ratio. The power spectral density of the IEEE 802.11b is considered in ...

This paper reports on the design and implementation of multi-criteria vertical handoff decision algorithms in a heterogeneous wireless wide area network (WWAN) and a wireless local area network (WLAN) environment. An “IPcentric Field Workforce Automation” project aims to ensure free movement of field workers between networks while always connected in an IP mode, and to allow a user to use one d...

Radio resource management (RRM) is the system level control of co-channel interference and other radio transmission characteristics in wireless communication systems. In this paper we first analyze a utility function based access selection (UFAS) method. Then we investigate a radio resource management and network selection scheme in heterogeneous wireless network. We propose an economic model t...

Recent developments in wireless local area network (WLAN) technologies are raising new hopes for sustainable Internet diffusion in the rural areas of the developing world. These technologies allow drastic reductions in network deployment costs, particularly for last-mile connectivity in low-density areas. More important, the technologies make possible an infrastructure development model based o...

Wired WLAN (Wireless Local Area Network) technology emerged as the most widely used network. is suitable for those who need internet. By using will be found various advantages its users. Likewise with WiMAX (Worldwide Interoperability Microwave Access) wireless technology, basically has a function similar to WLAN, but certain small differences. can cover one local area, in contrast which metrop...

Wireless local area network (WLAN) technology is one of the fastest growing areas in the information technology sphere, and with good reason. The benefits of using wireless include reduced move/add/change costs, the elimination of wire plant requirements in new workspace or older structures that pose challenges for traditional wiring, mobility of workers and data, and many others. While this gr...
