The stability and throughput of the Slotted Aloha protocol have been studied at length,
yielding results that depend on the environment and channel assumptions, in many cases …

We consider a slotted Aloha-based wireless communication network comprising a source
and an active relay, both transmitting to a common destination. The relay node is able to …

Most publications on the capacity and performance of wireless ad hoc networks share the
underlying assumption of a uniform random distribution of nodes. In this paper, we study the …

We consider the uplink case of a cellular system where m bufferless mobiles transmit over a
common channel to a base station, using the slotted aloha medium access protocol. We …

Prior investigations on the Aloha network have primarily focused on its system throughput.
Good system throughput, however, does not automatically translate to good delay …

The impact of imperfect channel state information (CSI) on the transmission control of
channel-aware slotted ALOHA networks is studied in this work. By taking into consideration …

This letter analyzes the impact of packet retransmissions on the performance of wireless
random access protocols. In particular, we focus on the effects of two controllable …

The aim of this paper is to analyze the Aloha medium access (MAC) scheme in one-
dimensional, linear networks, which might be an appropriate assumption for Vehicular Ad …

We consider an ad hoc network which uses multihop and slotted ALOHA for its MAC
contention. We then formulate the minimum time required for a packet to reach the …

The sum rate performance of random-access networks crucially depends on the access
protocol and receiver structure. Despite extensive studies, how to characterize the maximum …
