Optimal Channel Pairing and Power Allocation for Multi-channel Multi-hop Relay Networks
We study the problem of channel pairing and power allocation in a multi-channel, multi-hop relay network to enhance the end-to-end data rate. OFDM-based relays are used as an illustrative example, and the amplify-andforward and decode-and-forward relaying strategies are considered. Given fixed power allocation to the OFDM subcarriers, we observe that a sorted-SNR subcarrier pairing strategy is ...
متن کاملStatic Channel Assignment for Multi-Radio Multi-Channel Multi-Hop Wireless Networks
Multi-radio multi-channel multi-hop wireless networks recently have drawn considerable research attention. A number of results have been presented on joint optimization of routing, link scheduling, and channel assignment in such networks. Although dynamic channel switching has some benefits, it also poses a number of challenges in managing the network protocols and causes delay in switching cha...
متن کاملRouting and Channel Assignment in Multi-Channel Multi-Hop Wireless Networks with Single-NIC Devices
In this paper, we present a routing and channel assignment protocol for multi-channel multi-hop wireless networks. We consider a multi-hop network, where a mobile host may connect to an access point using multi-hop wireless routes, via other mobile hosts or wireless routers. Also, we consider a multi-channel network where multiple non-overlapping (orthogonal) channels are available, and each ho...
متن کاملRouting and Channel Assignment in Multi-Channel Multi-Hop Wireless Networks with Single Network Interface
In this paper, we present a routing and channel assignment protocol for multi-channel multi-hop wireless networks. We view a multi-hop network as an extension to infrastructure networks, where a mobile host may connect to an access point using multi-hop wireless routes, via other mobile hosts or wireless routers. The access points are configured to operate on one of multiple available channels....
متن کاملJointly multi-user detection and channel estimation with genetic algorithm
This work aims at proposing the use of the evolutionary computation methodology in order to jointly solve the multiuser channel estimation (MuChE) and detection problems at its maximum-likelihood, both related to the direct sequence code division multiple access (DS/CDMA). The effectiveness of the proposed heuristic approach is proven by comparing performance and complexity merit figures with t...
