Efficient Contention Window Control with Two-Element Array
نویسندگان
چکیده
in wireless networks, the sharing channel has limited communication bandwidth. So designing efficient Medium Access Control (MAC) protocol with high performances is a major focus in distributed contention-based MAC protocol research. IEEE 802.11 MAC protocol is the most famous standard in this area. But, this standard has a problem with adopting its backoff range based on channel status. It causes some problems in throughput and fairness in a real situation. In this paper, we propose a simple algorithm that maximizes the throughput and fairness among competing nodes. We have divided nodes into four section of our backoff range. Numerical results show improvement in all performances except end to end delay.

Transmission opportunity limit and contention window are two influenced parameters in accessing the media in the networks based IEEE 802.11e standard. In these networks, every wireless station by setting of its contention window value, determines the chance of access to wireless media. Furthermore, a transmission opportunity limit provides a period of transmission without contact for a station....

Mobile Ad Hoc Network (MANET) is a collection of nodes that can be rapidly deployed as a multi-hop network without the aid of any centralized administration. Misbehavior is challenged by bandwidth and energy efficient medium access control and fair share of throughput. Node misbehavior plays an important role in MANET. In this survey, few of the contention window misbehavior is reviewed and com...
متن کاملImpact Of Mobility and Transmission Range On The Performance of Backoff Algorithms For IEEE 802.11-Based Multi-hop Mobile Ad hoc Networks
The medium access control (MAC) protocol is the main element which determines the system performance in wireless local area networks. The MAC technique of the IEEE 802.11 protocol is called Distributed Coordination Function (DCF). In IEEE 802.11 Wireless Local Area Networks (WLANs), network nodes experiencing collisions on the shared channel need to backoff for a random period of time, which is...
متن کاملAn Efficient Multiaccess Protocol for Wireless Networks
In this paper, we propose and evaluate an efficient multiaccess protocol for cell-based wireless networks. Our protocol addresses the problems in existing random-access protocols for wireless networks: long-term fairness as well as short-term fairness in accessing a shared channel and the detection of hidden and exposed collisions. Our proposed protocol is a limited contention protocol in which...
متن کاملAn Adaptive Contention Window Control for Improving DCF Throughput and Fairness
The IEEE 802.11 provides a MAC layer protocol for controlling competition among nodes to access the channel in wireless local area network. Recent works show that this standard has not suitable performances in mobile ad-hoc networks and especially in error prone channels. Many researchers proposed many algorithms to improve this standard like HBCWC (History Based Contention Window Control) sche...
