We address the problem of cooperative retransmission in the media access control (MAC)
layer of a distributed wireless network with spatial reuse, where there can be multiple …

The challenging problem of cooperative retransmission in the wireless networks is
investigated in this paper. This paper introduces the centralized and distributed Markov …

Cooperative communication exploits spatial diversity via relay node antennas to increase
data rates in wireless networks. Relay node selection, therefore, plays a critical role in …

Perfect channel state information (CSI) is usually required when considering relay selection
and power allocation in cooperative communication. However, it is difficult to get an accurate …

Due to a number of attractive advantages, cooperative communications have been widely
regarded as one of the promising techniques to improve throughput and coverage …

In this paper, we study the outage probability minimizing problem in a two-hop cooperative
relay network. To reduce outage probability, existing studies propose many schemes for …

A transmitted packet that fails to reach its intended destination may be correctly received by
neighbor nodes due to the broadcast nature of the wireless medium. In a cooperative …

Relay selection in cooperative communication is a crucial task for achieving the spatial
diversity since the improper relay selection can decrease the overall capacity of the network …

Cooperative communication has great potential to improve the transmit diversity in multiple
users environments. To achieve a high network-wide energy-efficient performance, this letter …

In this work, we investigate a slotted-time relay assisted cooperative random access wireless
network with multipacket (MPR) reception capabilities. MPR refers to the capability of a …
