The hybrid half-duplex/full-duplex (HD/FD) relaying scheme is an effective paradigm to overcome the negative effects of the self-interference incurred by the full-duplex (FD) mode. However, traditional hybrid HD/FD scheme does not consider the diversity gain incurred by the multiple antennas of the FD node when the system works in the HD mode, leading to the waste of the system resources. In th...

Prolonged network lifetime, scalability, and load balancing are important requirements for many adhoc sensor network applications. Clustering sensor nodes is an effective technique for achieving these goals. In this work, we propose a new hybrid energy-efficient approach for clustering nodes in ad-hoc sensor networks. Based on this approach, we present a protocol, HEED (Hybrid Energy-Efficient ...

We consider the problem of minimizing the delay of jobs moving through a directed graph of service nodes. In this problem, each node may have several links and is constrained to serve one link at a time. As jobs move through the network, they can pass through a node only after they have been serviced by that node. The objective is to minimize the delay jobs incur sitting in queues waiting to be...

An important issues in the design of interconnection networks for massively parallel computers is scalability. A new scalable interconnection network topology, called Double-Loop Hypercube (DLH), is proposed. The DLH network combines the positive features of the hypercube topology, such as small diameter, high connectivity, symmetry and simple routing, and the scalability and constant node degr...

Hybrid <span>wireless networks (HWNs) are resulted from the integration of a mobile Ad hoc (MANET) and an infrastructure wireless networks. These have received increasing interest researchers for their superior performance reliability. Packet routing protocols in hybrid important to increase capacity scalability these networks, therefore, several been proposed. Routing HWNs designed imple...
