Abstract. The RTS/CTS access scheme, designed to reduce the number of collisions in a IEEE 802.11 network, is known to exhibit problems due to masked nodes, the imbalance between the interference range and the communication range of the nodes, and scenarios in which nodes are unnecessarily silenced, thus preventing parallel transmissions to take place. We present an approach for enhancing the performance of the IEEE 802.11 MAC protocol by selectively discarding or delaying specifically marked RTS and CTS packets. By dropping the circularity-satisfied RTS, we allow certain parallel transmissions to proceed, even if there is a non-zero risk of collision. By delaying the circularity-satisfied CTS, we allow a neighboring parallel transmission to continue. One important feature of the circularity approach is that it is fully compatible with the IEEE 802.11 standard. We implemented the circularity approach in ns-2 simulator. Through a series of experiments, we show that the circularity approach provides a significant improvement in the throughput and end-to-end delay of the network, and contributes to a reduction of the number of collisions in most scenarios.

“…A single access point can support a small group of users and can function within a range of less than one hundred to several hundred feet. The access point (or the antenna attached to the access point) is usually mounted high but may be mounted essentially anywhere that is practical as long as the desired radio coverage is obtained [1][2][3][4] .…”

A wireless network system based on an infrared and Laser scanning Physical Token Ring architecture (W-PTRS) was designed, built and tested successfully. The network provides a different way of utilizing the concept of a token ring network but with a higher efficiency related to the speed of data transfer and the ability to parallel process client-server requests leading to a new concept of the token ring system, which will not fail simply because of ring breakage. The study proposes a new wireless communication protocol, which is neither IEEE802.11 nor Bluetooth. This newly developed protocol could prove to be an excellent communication media if supported by industry. If implemented, this wireless system will provide an alternative but efficient way of wireless communication.

“…The devices are characterized by low cost, flexibility and ease to use. IEEE 802.11 [3], a Institute of Electrical and Electronics Engineers (IEEE) standard, is the widely used standard for WLAN. The scope of this standard is to develop a Medium Access Control (MAC) and physical layer specification for wireless connectivity for fixed, portable, and moving stations within a local area.…”

Abstract-The method of obtaining the physical co-ordinates of a device is known as localization. Location information of the wireless devices in a network has many applications. Generally we use GPS (Global Positioning System) to get the location but it fails to provide the service in an indoor environment. Therefore we need a local positioning system, which can provide the relative location information in a network. Many approaches has been made for wireless localization using the distance obtained through
