Joint power, subcarrier and subframe allocation in Multihop relay networks
In this paper we study the problem of subframe, subchannel and power allocation in OFDMA-based multihop relay networks. The system consists of a base station (BS), a number of relay stations (RS) and mobile stations (MS). We consider frame by frame scheduling, where the frame is divided into two subframes such as BS-RS and RSMS subframes. We study two different problems, satisfying link rate re...
متن کاملPower and Subcarrier Allocation Scheme for Uplink OFDMA
In this contribution, we propose a power and subcarrier allocation scheme for uplink orthogonal frequency division multiple access (OFDMA) based on the capacity difference between different users. The scheme works iteratively and performs three major tasks. In the first step, the subcarrier with largest capacity difference of two active users is found. Then, the subcarrier selection of these tw...
متن کاملJoint Subcarrier Matching and Power Allocation for OFDM Multihop System
Relay networks have recently attracted extensive attention due to its potential to increase coverage area and channel capacity. In a relay network, a source node communicates with a destination node with the help of the relay node. The performances of improving the channel capacity and coverage area have been explored and evaluated in the literature (Sendonaris et al., 2003)-(Laneman et al., 20...
متن کاملReciprocally opportunistic spectrum access
The problem of opportunistic spectrum access in cognitive radio networks (CRNs) is considered in this paper. Especially, we discuss designing distributed learning protocols for non-cooperative secondary users (SUs) to efficiently utilize the spectrum opportunities. It is well known that the SUs’ selfish behaviors will result in a network collapse. Each SU is thus enabled to form conjectures ove...
متن کاملController Placement in Software Defined Network using Iterated Local Search
Software defined network is a new computer network architecture who separates controller and data layer in network devices such as switches and routers. By the emerge of software defined networks, a class of location problems, called controller placement problem, has attracted much more research attention. The task in the problem is to simultaneously find optimal number and location of controll...
