A novel algorithm for the fast detection of hubs in chemical networks is presented. The algorithm identifies a set of nodes in the network as most significant, aimed to be the most effective points of distribution for fast, widespread coverage throughout the system. We show that our hubs have in general greater closeness centrality and betweenness centrality than vertices with maximal degree, w...

WIMAX relay station mesh network has been approved by IEEE 802.16j as a standard to provide a highly data rate transmission, the RS was implemented to extend the coverage zone of the BS, for instance the MSs previously were out of the coverage of the BS they become in the coverage of the RS, therefore these MSs can have Admission control from the BS through the RS. This paper describe a problem...

How to best solve the coverage problem has always been a critical issue in wireless sensor networks; this paper focuses on redundant network nodes, short life cycle and other defects and firstly sets nodes utilization and network effective coverage as optimization goals, so as to establish relevant mathematical model, and then introduce the inverse Gaussian mutation algorithms on AFSA, making t...

Sensing coverage is a critical issue in sensor network deployments. We propose a novel scheme to maintain the sensing coverage in sensor networks, which we call CASS (Coverage-Aware Self-Scheduling). Different from the existing work on coverage maintenance, CASS probabilistically schedules a sensor’s sensing activities according to the sensor’s contribution to the sensing coverage. CASS is desi...
