Scaling the size of parallel systems while maintaining the system performance is an important problem. A default scaling approach by using larger networks to interconnect more processors works only up to a limited extent and the derived conngurations using this approach are not cost-eeective.

We consider two closely related fundamental clustering problems in this paper. In the min-sum k-clustering one is given a metric space and has to partition the points into k clusterswhile minimizing the sum of pairwise distances between the points within the clusters. In theBalanced k-Median problem the instance is the same and one has to obtain a clustering into kcluster C1, . ...

The multiplication of large spare matrices is a basic operation in many scientific and engineering applications. There exist some high-performance library routines for this operation. They are often optimized based on the target architecture. For a parallel environment, it is essential to partition the entire operation into well balanced tasks and assign them to individual processing elements. ...

In this paper we discuss some problematic aspects of Newman’s modularity function QN . Given a graph G, the modularity of G can be written as QN = Qf −Q0, where Qf is the intracluster edge fraction of G and Q0 is the expected intracluster edge fraction of the null model, i.e., a randomly connected graph with same expected degree distribution as G. It follows that the maximization of QN must acc...

Due to the restricted communication range and high network density, events forwarding in Wireless sensor networks is very challenging, and require multi-hop data forwarding. Improving network lifetime and network reliability are the main factors to consider in the research. In this paper, we propose an Energy-balanced Clustering Routing Algorithm based on Distance Vector, called ECRD. The opera...

Understanding how multiple signals are integrated in living cells to produce a balanced response is a major challenge in biology. Two-component signal transduction pathways, such as bacterial chemotaxis, comprise histidine protein kinases (HPKs) and response regulators (RRs). These are used to sense and respond to changes in the environment. Rhodobacter sphaeroides has a complex chemosensory ne...

Internet-of-Things (IoT)-based Heterogeneous Wireless Sensor Network (HWSN) has emerged as a prevalent technology that plays significant role in developing various human-centric applications. Like wireless sensor network (WSN), energy is also the most crucial resource IoT-based HWSN. The researchers have proposed many works to achieve energy-efficient operations by minimizing usage. A vast prop...
