Packet Loss Discrimination in Multi-Cell 802.11 Wireless LANs
نویسندگان
چکیده
Packet loss in 802.11 WLANs can occur either due to collision or a signal that is not strong enough at the receiver antenna. A challenging issue is the determination of packet loss cause once it occurs, which is a key for improving the performance of 802.11 WLANs. This report proposes and evaluates an algorithm to achieve this goal. The core of this algorithm is power level statistics at the receiver MAC. It learns from the received power levels of both correct and corrupted packets and decides whether a packet is lost due to collision or a weak signal.

Nowadays wireless networks are becoming important in personal and public communication andgrowing very rapidly. Similarly, Software Dened Network (SDN) is an emerging approach to over-come challenges of traditional networks. In this paper, a new SDN-based framework is proposedto ne-grained control of 802.11 Wireless LANs. This work describes the benets of programmableAcc...
متن کاملAn Adaptive Link Adaptation Scheme for Multi-rate Wireless LANs
In this paper, we propose an efficient rate switching scheme for IEEE 802.11 Wireless LANs. The proposed scheme switches the transmission rate by the patterns of transmission successes and failures, and the measured signal strength of a recently received packet. Our simulation study shows that the proposed scheme shows better performance than existing rate adaptation schemes. Key-Words: link ad...
متن کاملHigh-performance architectures for IP-based multihop 802.11 networks
The concept of a forwarding node, which receives packets from upstream nodes and then transmits these packets to downstream nodes, is a key element of any multi-hop network, wired or wireless. While high-speed IP router architectures have been extensively studied for wired networks, the concept of a “wireless IP router” has not been addressed so far. In this paper, we examine the limitations of...

Wireless LANs are becoming commonplace because of their ease in providing mobile communication. As use of IEEE 802.11 continues to expand, support for voice will Preprint submitted to Elsevier Science 2 December 2004 become a desirable feature. Supporting voice conversations over a packet network is more challenging than over current circuit switched wired networks. These challenges are particu...
متن کاملPerformance of wireless LANs based on IEEE 802.11 MAC protocols
IEEE 802.11 MAC protocol has been the standard for Wireless LANs, and also adopted in many network simulation packages for wireless multi-hop ad hoc networks. However, it is well known that, as the traffic goes up, the performance of IEEE 802.11 MAC drops dramatically in terms of delay and throughput, especially when the station approaches its saturation state. To explore the inherent problems ...
