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 CSI in practical situations. In this letter, we study the outa

Recent years have witnessed growing interests in vehicular ad hoc network (VANET) topology. Existing works assume that the networks generated at each time are independent. In these works, the VANET topologies are formed based on simple traffic and co
Cooperative communication is an effective approach to improve spectrum utilization. In order to reduce outage probability of communication system, most studies propose various schemes for relay selection and power allocation, which are based on the a

Recent years have witnessed extensive research in the characteristics of vehicular ad hoc network (VANET) topology. Some papers in the literature use a simple model to generate a VANET topology at a certain time. Different from the existing works, we

This paper addresses the robust beamforming design for a downlink cloud radio access network (cloud RAN) subject to per-base-station (BS) power constraint and individual signal-to-interference-plus-noise ratio (SINR) requirements. Our objective is to

This study considers utility-based resource allocation in backbone wireless mesh networks (WMNs). Unlike single-hop cellular networks, a WMN has multi-hop transmissions with multiple contending links, and thus requires more careful design for resourc

We consider a cognitive radio network where the primary user (PU) supports applications with multiple quality of service (QoS) requirements via orthogonal frequency division multiple access (OFDMA). To let the secondary users (SUs) be aware of PU’s

We study the problem of cooperative transmission, relay selection and scheduling in battery-operated wireless networks, where energy efficiency is a critical design consideration. We assume that multiple relay nodes in the network can cooperate their

Compared with cellular networks, wireless mesh networks (WMNs) need more careful design for resource allocation. To this end, we develop a clique-based proportional fair scheduling (CBPFS) algorithm for WMNs. Furthermore, we obtain a closed-form mode

We consider the problem of selective relaying in multi-hop networks. At each slot, a relay and a node along the optimal non-cooperative path are opportunistically selected to transmit to the next-hop node in a cooperative manner. Being a promising sc
