Wireless Local Area Networks (WLANs) based on IEEE 802.11a/b/g standards are growing rapidly. WLANs can provide the benefits of network connectivity without the restrictions of being tied to a location or restricted by wires. Despite this convenience of mobility, the performance of a WLAN must be addressed carefully before it can be adopted and dep...

A novel multistubs loaded resonator (MSLR) is proposed in this article, which is constructed by several open- and short-circuited stubs. The analysis shows that it is characterized by four resonant modes. Then, the MSLR is applied in the design of a compact ultra-wideband (UWB) bandpass filter. The measured results show that its 3dB bandwidth can c...
Both the inherently wideband differential-chaos-shift-keying (DCSK) modulation and the space-time block code (STBC) are techniques that can mitigate the effect of multipath fading. By applying STBC at the chaotic segment level, a novel analog STBC-DCSK scheme is proposed in this paper. The proposed scheme is a simple configuration that combines the...
A simple decoupling technique utilizing the same radiator geometry as the resonator‐based decoupling structure for the isolation enhancement is proposed. The design consists of two identical radiating monopoles and the same radiator grounded between the two monopoles. The targeted design footprint of the two‐antenna system occupies a size of 5 mm ×...
Recent investigations show that (i) access points (APs) of wireless local area networks (WLANs) are idle during much of the time, and, (ii) an AP in its idle state without forwarding any packets still consumes a large percentage of power. Therefore, it is necessary to put idle APs into sleep so as to realize green WLANs. The problem, however, is ho...
A novel dual ultra-wideband (UWB) microstrip slot antenna is proposed in this paper. Its dual-band response is realized by subtracting a T-shaped slot and two rectangles at two corners and two triangles at the other two corners on the radiation patch. The two bands are operating at 2.45 and 5.2 GHz, respectively, which can be used for Wireless Loca...

... The first standard taking into consideration the new constraints of the indoor sensor networks, is the 802.15.4 standard. Other reason why we selected ZigBee is because it has been shown that ZigBee network noise is the least compared with other wireless networks in term of SNR [4,5] us referred infigure 1. In fact, in an indoor environment, noise has a strong presence especially in industrial buildings where machines cause high levels of it. ...
In this paper, we present a real indoor application for improved " Cluster Tree " network using Zigbee sensor nodes integrated with " Arduino " microcontrollers where the main goal is to study the efficiency of our improved clustering topology based on Minimum Spanning Tree (MST) construction under real conditions. Our system is based on many sensor nodes deployed all over a building to monitor temperature and humidity and detect any brutal temperature increase. These nodes are based on simple , cheap and easily programmed equipment. while several simulations using NS-2 and other simulators has been conducted in many other works to study the efficiency of a network based on MST, our application tests this topology in real conditions to ensure it effectiveness in a Zigbee network. Our developed system provides an easy interface for programming and displaying results. All sensed data is sent to the coordinator which forwards it to the user's pc to be viewed by the user. This paper also presents some performances of this discussed topology obtained by real conditions tests.
... Performance evaluation of multi-channel wireless networks consisting of IEEE 802.11g devices using non-overlapping channels can be calculated and transmission power and packet size have significant influence on the performance of multi -channel wireless network [8]. There are different parameters that actually affect the performance of 802.11g protocols [9]. Results against the parametric studies are significant in nature concluded as throughput can be achieved by controlling various key parameters [10]. ...
The aim of this research is to measure the performance of multi-channel wireless network using throughput and response time performance metrics with antenna separation, transmit power, TCP windows size, and UDP buffer size/datagram and frequency channel scheme factors. The main purpose to study the multi-channel wireless networks is to increase the bandwidth. In our research we have characterized the performance of multi-channel wireless networks consisting of IEEE 802.11b or IEEE 802.11g devices. We have conducted experiments on a simple topology consisting of two access points having same or non-overlapping frequency channels. Research study shows the effect of change in frequency channels, change in transmission power, and change in TCP windows size or UDP datagram size on performance. The results of this study are important contribution when configuring a multi-channel wireless network with non-overlapping frequency channels.
... In order to assess the effect of the co-channel interference on the performance of the network, the highest possible throughput that we could get without interferences (with Inter- Packet Delay set to 1 ms and packet size equal to 1460 bytes) was measured and this throughput was considered as the base line. The results of the experiments [2] The results show that the throughput suffers heavily due to co-channel interference. ...
WLAN uses frequency spectrum for providing wireless access to nomadic nodes which is in fact a very scarce resource. One common issue in deployment of a multi-channel multi-AP wireless network is interference. One of the reasons why theoretical throughput (54 Mbps for 802.11g) can't be achieved is co-channel interference. In this paper, the effect of co-channel interference on data throughput has been studied in a practical multiple AP (access point) scenario. Interference can be minimized by adjusting the transmission power. This paper also provides an algorithm for transmission power adjustment of APs by using the concept of cognitive radio, which eventually helps in minimizing co-channel interference.
... available products are capable of 54 Mbps signaling rate, the practical or "actual" data throughput is more likely to be much less than that (in the range of 10-12 Mbps). By experimental results, we showed in a previous work [8] that the co-channel interference clearly degrades drastically the TCP throughput (from 9Mbps to 2 Mbps) and UDP throughput from 9.7 Mbps to 8.6 Mbps. TCP suffering more than UDP due to the delays incurred by the retransmission and error detection. ...
In this paper, we propose a dynamic channel-assignment algorithm which minimizes the total interferences between access points (APs) of a Wireless Local Area Network (WLAN), while maintaining the Signal to Interferences Ratio (SIR) bigger than a certain threshold for all users. The algorithm initializes the channel assignment at the APs, and calculates the SIR for each user using Integer Linear Programming "ILP" for an open area and for an area with obstacles (walls). The proposed algorithm shows results with significant enhancement of the SIR over WLANs, and therefore an improvement of the throughput. The algorithm can be applied to any WLAN, irrespective of the user distribution and user load.
In this article, we propose a network planning algorithm for IEEE802.11g, which minimises the total interferences between access points while maintaining a required quality of service (QoS), measured by users' signal to interference ratio (SIR). Three planning problems are formulated as integer linear programs. (1) A frequency assignment problem, which assigns frequencies to access points while minimising total interferences and ensuring users' SIR higher than a required threshold. (2) Assuming the optimal frequency assignment, a power management problem is modelled to assign five different power levels to access points while reducing the network total interference and ensuring the required QoS is met. (3) Given the frequency and power assignments, a load balancing problem is formulated to minimise the maximum number of users assigned per access point, taking into consideration users' QoS. Once the planning is done, new joining users are dynamically assigned to the less loaded acceptable access point. Based on realistic scenarios analysis, we show that the proposed planning achieves significant improvement in average user SIR and power savings while balancing the network. In fact, for one of the analysed scenarios the algorithm achieved 55% power savings while the SIR increased by 6 dB improving the QoS.
