Sharing Channel In IEEE 802.16 Using The Cooperative Model Of Slotted ALOHA
نویسندگان
چکیده
One of the main problems in WIMAX is to share the medium by multiple users who compete for access. Various random access mechanisms, such as ALOHA and its corresponding variations have been widely studied as efficient methods to coordinate the medium access among competing users. In this paper the slotted ALOHA protocol is implemented as a two-state system. Using Markov Models, we evaluate the channel utilization and we analyze the throughput under different fairness conditions. The cooperative team problem is considered.

Analysis of Performance Parameters in Wireless Networks by using Game Theory for the non Cooperative Slotted Aloha Enhanced by ZigZag Decoding Mechanism
In wireless communication networks, when the workload increases, sources become more aggressive at the equilibrium in the game setting in comparison with the team problem by using slotted Aloha mechanism. Consequently, more packets are in collision and are lost. To reduce these phenomena and to enhance the performance of the networks, we propose to combine ZigZag decoding approach with non coop...
متن کاملPerformance analysis of slotted random access channels for W-CDMA systems in Nakagami fading channels
We perform a new analysis of the performance of the wide-band code-division multiple access (W-CDMA) randomized slotted-offset random access channel with Nakagamifading and compare it with the performance of a comparable randomized slotted-ALOHA-based random access channel. In a previous paper, it was shown through simulations that the W-CDMA random access channel is fast, robust, and simple to...
متن کاملProposed ST-Slotted-CS-ALOHA Protocol for Time Saving and Collision Avoidance
Time Saving and energy consumption has become a vital issue that attracts the attention of researchers in Underwater Wireless Sensor Networks (UWSNs) fields. According to that, there is a strong need to improve MAC protocols performance in UWSNs, particularly enhancing the effectiveness of ALOHA Protocol. In this paper, a time-saving Aloha protocol with slotted carrier sense proposed which we c...
متن کاملDelay distributions of slotted ALOHA and CSMA
In this paper, we derive the closed-form delay distributions of slotted ALOHA and nonpersistent carrier sense multiple access (CSMA) protocols under steady state. Three retransmission policies are analyzed. We find that under a binary exponential backoff retransmission policy, finite average delay and finite delay variance can be guaranteed for 2 and 4 3, respectively, where is the channel traf...
