Network-on-chip (NoC) has emerged as a vital factor that determines the performance and power consumption of many-core systems. This paper proposes a hybrid scheme for NoCs, which aims at obtaining low latency and low power consumption. In the presented hybrid scheme, a novel switching mechanism, called virtual circuit switching, is proposed to intermingle with circuit […]

Impulsive Multiconsensus of Second-Order Multiagent Networks Using Sampled Position Data
A multiconsensus problem of multiagent networks is solved in this paper, where multiconsensus refers to that the states of multiple agents in each subnetwork asymptotically converge to an individual consistent value when there exist information exchanges among subnetworks. A distributed impulsive protocol is proposed to achieve multiconsensus of second-order multiagent networks in terms of three […]

Multiuser Admission Control and Beamforming Optimization Algorithms for MISO Heterogeneous Networks
This paper investigates the problem of joint multiuser admission control and beamforming optimization for multiple-input single-output (MISO) heterogeneous networks (HetNet). Considered is a HetNet where multiple newly deployed femtocell base-stations (FBS) have the coverage overlapped with that of an existing macrocell base-station (MBS). The design objective is to serve as many femto-users (FUE) as possible […]
Read moreThe diversity provided by disjoint paths can increase the survivability of communication networks. This paper considers the allocation of network error correction flow on a network that consists of disjoint paths from the source node to the destination node. Specifically, we propose an algorithm of allocating the path-flows to support the given rate with minimum […]
Read moreIn this paper, we describe dynamic unicast to increase communication efficiency in opportunistic Information-centric networks. The approach is based on broadcast requests to quickly find content and dynamically creating unicast links to content sources without the need of neighbor discovery. The links are kept temporarily as long as they deliver content and are quickly removed […]
Read moreFuture wireless networks will face the dual challenge of supporting large traffic volumes while providing reliable service for delay-sensitive traffic. To meet the challenge, relay network has been introduced as a new network architecture for the fourth generation (4G) LTE-Advanced (LTE-A) networks. In this paper, we investigate resource allocation including subcarrier and power allocation for […]
Read moreThe ability to control the behavior of intracellular networks has relevant applications, ranging from an optimized synthesis of metabolites in bacteria to the cure of human diseases. To implement a controller in vivo, one may insert synthetic biomolecules into the cell being controlled. This paper develops a formal approach, based on Supervisory Control Theory (SCT), […]
Read moreReducing the operating energy of a distributed feedback (DFB) laser is a critical issue if we are to use the device as a directly modulated light source employing wavelength division multiplexing technologies in short-distance datacom networks. A membrane buried heterostructure (BH) DFB laser on a SiO2layer is one candidate for reducing the operating energy because […]
Read moreNext generation cellular network is expected to overcome the issues like demand for high data rates, better network coverage, energy, and spectrally efficient system. In this paper, femto based heterogeneous cellular network (HCN) with cognitive approach is considered to address these issues. This paper investigates two tier cognitive based HCN for overlay, underlay, and mixed […]
Read moreAn efficient decoupling feeding network is proposed in this letter. It is composed of two directional couplers and two sections of transmission line for connection use. By connecting the two couplers, an indirect coupling with controlled magnitude and phase is introduced, which can be used to cancel out the direct coupling caused by space waves […]
