Performance analysis for a stabilized multi-channel slotted ALOHA algorithm [PDF]

, 2003
We study slotted ALOHA with multiple random access channels, the so called multi-channel ALOHA (MC-ALOHA). It is well known that single-channel ALOHA (SC-ALOHA) is unstable. Not surprisingly, MC-ALOHA is also unstable.

A Game of Ages for Slotted ALOHA With Capture

IEEE Transactions on Mobile Computing
Within a recent line of research, age of information is supported as an alternate network performance metric with respect to throughput or delay, to evaluate the performance of medium access techniques, especially for remote sensing applications. Analytical investigations based on game theory have shown how selfish players can behave efficiently in ...

Slotted ALOHA 및 FH-CDMA/Slotted ALOHA 통신망에서의 입력추정을 이용한 입력 및 재전송 제어

, 1998
학위논문(석사) - 한국과학기술원 : 전기및전자공학과, 1998.2, [ vi, 57 p. ]The packet collision in slotted ALOHA and FH-CDMA network deteriorates the performance of the networks. Moreover, it causes the slotted ALOHA network to be unstable.

Minimizing Age of Information in Slotted ALOHA With Short-Packet Communications

IEEE Access
Age of information (AoI) has emerged as a novel metric for quantifying the freshness of information at the receiver side. This metric has found numerous applications in real-time monitoring and control systems where stale information may lead to critical
