Aloha [1] and slotted aloha [2] have long been used as randomly distributed medium access
protocols for radio channels. They are used in satellite networks and cellular telephone …

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 …

Intelligent medium access control (MAC) protocols have been a vital solution in enhancing
the performance of a variety of wireless networks. ALOHA, as the first MAC approach …

The intrinsic characteristics of wireless Ad hoc network, such as self-organizing, self-
configuration and self-adaptation, make this kind of network an attractive solution in several …

The throughput performance of a mobile S-ALOHA network can be improved considering
the capture phenomenon, which also depends on the spatial distribution of the mobiles …

In wireless communication systems, the signal strength/quality generally varies with the
distances between transmitters and receivers. As a consequence, the throughput in the MAC …

The problem of media access control (MAC) implies significant challenges when
considering the relocation of mobile nodes. In the algorithmic arena of MAC solutions it is …

Random and decentralised channel access by hosts in the wireless broadcast network is
highly susceptible to packet collisions, information loss and alleviated system throughput …

In this paper the interference process in an unslotted Aloha network using two power levels
is used to obtain the throughput in a channel with power capture. In the model considered …

A new scheme, namely ALOHA with Collision Resolution (ALOHA-CR) is proposed, which is
a cross-layer approach for high throughput wireless communications in a cellular uplink …
