Cooperative-Diversity Slotted ALOHA
Second International Conference on Quality of Service in Heterogeneous Wired/Wireless Networks (QSHINE'05), 2005We propose a cooperative-diversity technique for ad hoc networks based on the decode-and-forward relaying strategy. We develop a MAC protocol based on slotted ALOHA that allows neighbors of a transmitter to act as relays and forward a packet toward its final destination when the transmission to the intended recipient fails.

On the instability of slotted aloha with capture
IEEE Transactions on Wireless Communications, 2004We analyze the stability properties of slotted Aloha with capture for random access over fading channels with infinitely-many users. We assume that each user node knows only its own uplink channel gain, and uses this decentralized channel state information (CSI) to perform power control and/or probability control.

Cooperation and Fairness for Slotted Aloha
Wireless Personal Communications, 2006Wireless access based on slotted Aloha with selfish users may result in very inefficient use of the system resources. To impose cooperation and fairness in such systems, we propose an optimal pricing strategy, based on which the service provider can regulate the overall network behavior.

On the channel spacing of multichannel ALOHA
IEEE Communications Letters, 2003We investigate the performance of a multichannel radio access network with spectrally overlapped channels. Taking into account the adjacent channel interference, we derive a new expression for the throughput of the multichannel ALOHA with capture in Rayleigh fading environment.

Packet broadcasting is a technique whereby data is sent from one node in a net to another by attaching address information to the data to form a packet---typically from 30 to 1000 bits in length. The packet is then broadcast over a communication channel which is shared by a large number of nodes in the net; as the packet is received by these nodes the ...
