Abstract A reservation-based MAC protocol has been adopted by standards bodies as the basic protocol for data communication within the upstream channel of a cable plant. The available capacity is divided in two separate channels.

One is a random access channel, or contention channel, used to send requests to the head-end, with the possibility of collisions occurring therein. When collisions happen, they are resolved by using a Contention Resolution Algorithm (CRA). The second channel is a data channel to send user information in a collision-free manner. Adaptive algorithms are used to divide the system capacity dynamically, between the data and contention channels depending on the system requirements. In this paper the performance and implementation issues of p-persistence and tree-based CRAs under this adaptive environment are compared. While the complexity of the p-persistent algorithm remains as simple as in a traditional Aloha channel traditional implementations of the tree-based algorithms.

Abstract Abstract – Development of efficient medium access control (MAC) protocols providing both high through-put performance for data traffic and good quality of service (QoS) support for real-time traffic is the current major focus in distributed contention-based MAC protocol research. In this paper, we propose an effi-cient contention resolution algorithm for wireless local area networks, namely, the Fast Collision Resolu-tion (FCR) algorithm. The MAC protocol with this new algorithm attempts to provide significantly higher throughput performance for data services than the IEEE 802.11 MAC algorithm and more advanced dy-namic tuning backoff (DTB) algorithm. We demonstrate that this algorithm indeed resolves collisions faster and reduces the idle slots more effectively. Amarra wasapi for mac download.

To provide good fairness performance and to support good QoS for real-time traffic, we incorporate the self-clocked fair queueing algorithm and a priority scheme into the FCR algorithm and come up with the Real Time Fast Collision Resolution (RT-FCR) algorithm, and show that RT-FCR can simultaneously achieve high throughput and good fairness performance for non-real-time traffic while maintaining satisfactory QoS support for real-time traffic.
