“…This wireless interface can also be used for DATA exchange once the ATIM estimation is completed. (v) In a given beacon interval, all DATA frames of an active link are assigned to the same wireless interface, hence avoiding the frames out‐of‐sequence problem . (vi) To properly handle multi‐interfaces scenarios, mobile nodes protocol stack follows the cross‐layer model presented in our previous work .…”

Ad hoc wireless communications rely on beaconing to manage and maintain several network operations and to share relevant network parameters among network nodes. Beacon frames are sent at the start of each beacon interval. The frequency of beaconing depends on whether beacon intervals are fixed size or may be adapted and regulated according to the perceived network and workload conditions. On the other hand, current mobile nodes usually embed several heterogeneous wireless interfaces that urge the design of an adaptive beaconing strategy. In this paper, we propose an autonomous and adaptive beaconing strategy for multi-interfaced mobile wireless nodes that is capable of regulating the beacon interval size dynamically according to the perceived network conditions. The proposed strategy is based on a joint dynamic estimation of both the announcement traffic indication message (ATIM) window and the beyond-ATIM window sizes for each beacon interval. Extensive simulations were conducted using OMNeT++ to ascertain the improvements achieved by autonomously regulating the entire beacon interval to take into account the network and workload conditions. Obtained results showed that the two proposed approaches improve significantly the efficiency of the network in terms of throughput, end-to-end delay, and power consumption. The proposed fixed beacon interval (fixed-BI) approach stands as an enhanced version of the power-saving multi-channel MAC protocol (PSM-MMAC). The proposed variable beacon interval (variable-BI) approach, which regulates dynamically both of the ATIM and the beyond-ATIM windows, outperforms both the fixed-BI and the PSM-MMAC. In particular, under nominal traffic loads, the end-to-end delay of the variable-BI is much lower than those provided by the fixed-BI and PSM-MMAC.

Current information technology development continues to evolve along with the needs in obtaining data or information either audio, images or a combination of both which is growing rapidly. Therefore information technology must be able to provide services that could fulfill user expectations in terms of both quality and quantity. One of the prominent changes in information exchange field is the use of wireless technologies, including its network configurations. Besides having to function optimally, the performance of the wireless technology is also needed to be maintained. This research is about the technology performance of Wireless Distribution System (WDS) with point to multi-point network configuration using 802.11g access point. The research was conducted in two phases. The first phase was building a WDS network model using four access points that are connected to each other. The second one was examining WDS network performance on server side. Based on the results obtained seen throughput on each segment WDS tested in gradual decline and the sharpest occurred in the last segment. On the other side the value of jitter increased from WDS-1 to WDS-2 and WDS-3 in a normal number, as well as the value of packet loss which increased in a very good category. The results obtained indicate good quality and generally very appropriate WDS technology to expand wireless access.

“…This technology is not recommended for real time services such as peer-to-peer and interactive applications that are commonly used such as E-learning, VoIP, VoD, etc. Recent researches attempts to propose enhancements to find solutions [3]. Although this technology has the deficiencies described earlier, it is commonly used and proposed as an alternative to improve spectrum electromagnetic occupancy as each client is connected to its own Access Point (AP) rather than to the exterior node [4].…”

At present, the need for internet access in public area using wireless connections is increasing drastically and this should be supported by good network infrastructure. Wireless network is one of the best alternative in building a practical internet network. WDS is a system to develop wireless internet network without having to use cable as its backbone for access point but instead utilize wireless path from its access point. The problems that often arise in the design of wireless LAN network is the poor signal received by the user due to the installation of an access point that is poor location-wise. This is because at some point it is very difficult to install Access point using cable because the distance is too far from the existing router. In this paper, we propose to use three scenario of WDS mode to compare its performance. We investigate three different topology policy models of the WDS Bridge point-to-point, WDS Bridge point to multipoint and WDS repeater. The use of these three topologies aims to reach locations that are not covered by wireless LAN network, in addition this method can save the use of network resources such as LAN cables. Based on the simulation results, it is found that the topology point to point gives better value but it generated higher delays. The delay generated on point to point is higher than other topologies. Meanwhile, the measurement results are not much different on topology point to multipoint with repeater topology. The point to multipoint topology is slightly better than the repeater of the three QoS parameters.
