In this paper, a low-complexity delay-aware cross-layer scheduling algorithm for two-hop
relay communication systems is proposed. The complex interactions of the queues at the …

Slotted ALOHA is a simple and straightforward random multiple access technique, which
has been used extensively in data and cellular networks as the protocol for random access …

We consider uplink random access for which slotted Aloha has usually been employed with
unknown channel conditions. Upon failure of a transmission attempt, a user cannot tell …

Abstract Slotted ALOHA (S-ALOHA) is a classical medium access control protocol widely
used in multiple access communication networks, supporting distributed random access …

This thesis presents packet-level channel modeling, spectrum efficiency optimization and
channel estimation for wireless cooperative communication systems with diversity …

The complexity of state space based methods for analysis of finite user finite buffer (FU-FB)
random multiple access systems increases exponentially with buffer size and number of …
