Power Allocation In Cooperative Relay Channels

This paper concerns power allocation in relay-assisted wireless channels for two-hop transmission. First, the transmitter sends the information to both the relay and receiver parts. Next, in the second hop, the transmitter cooperates with the relay to increase the received signal to noise ratio (SNR), assuming the relay makes use of the Amplify and Forward (AF) strategy. Moreover, it is assumed...

Bacterial Foraging-based Power Allocation for Cooperative Wireless Sensor Networks

Cooperative communication becomes a popular area of research due to its strength and wide application scope in wireless networking and communications. This technique improves the communication performance largely in capacity enhancement, energy-efficiency, timeliness and contention. Power allocation plays an important role in the cooperative communication paradigm to get the desired performance...

Optimum Power Allocation in Cooperative Networks

Cooperation among network users provides transmit diversity in cases where wireless transmitters, due to size and power limitation, cannot support multiple antennas. We consider cooperation between M users, where each user achieves space-time diversity by using other users’ antennas as relays. Cooperation among users has been shown to achieve impressive gains as compared to a non-cooperative sy...

A Novel Opportunistic Relay and Energy Efficient Power Allocation Algorithm in Cooperative Wireless Sensor Networks

A series of challenges exist in the process of sensor network research which can not be solved by one sensor node. Cooperative communication, based on the idea of spatial diversity, which makes different users or nodes in wireless network share their antennas or other network resources, is a promising technique toward improving performance of wireless sensor network significantly. This article ...

A Cooperative Q-learning Approach for Real-time Power Allocation in Femtocell Networks

In this paper, we address the problem of distributed interference management of cognitive femtocells that share the same frequency range with macrocells (primary user) using distributed multi-agent Q-learning. We formulate and solve three problems representing three different Q-learning algorithms: namely, centralized, distributed and partially distributed power control using Q-learning (CPC-Q,...
