This paper proposes a new double iterative procedure for sum-rate maximization in a Multiuser MIMO system (MU-MIMO). The proposed algorithm is based on joint precoder and decoder optimization involving two different decoding schemes. For that we considered a precoding algorithm namely the iterative SJNR (Signal to Jamming and Noise Ratio) precoder combined with two iterative receivers. The first receiver...
In Vehicular Ad Hoc Network (VANET), the route between a source node and a destination node is intermittently broken. It is difficult to provide the reliable data transfer based on TCP because TCP is not adaptable to such networks such as VANET. Therefore, this paper proposes an end-to-end transfer rate adjustment mechanism in the application layer for VANET. The proposed mechanism consists of three...
In this paper we develop a discrete and distributed optimization framework that maximizes the overall spectral efficiency of heterogeneous networks while ensuring a minimum fairness among users. We split the problem into two subproblems: the first one is handled by the users and consists in a transmission by each user of a minimum rate requirement to the base stations and the second is the resource...
The number of multi-homed hosts with multiple network interfaces has been increasing due to cheaper network interface devices and network diversification. Concurrent Multipath Transfer (CMT) using SCTP multihoming is a mechanism that simultaneously transmits data via multiple end-to-end paths compatible with today's network environment. Present studies on CMT have assumed that each path uses a homogeneous...
