The static balancing of spherical three-degree-of-freedom (DoF) parallel mechanisms and manipulators is addressed in this paper. Static balancing is defined here as the set of conditions on mechanism dimensional and inertial parameters which, when satisfied, ensure that the weight of the links does not produce any torque (or force) at the actuators for any configuration of the mechanism, under ...

In this paper, we consider a class of sensor networks where the data is not required in real-time by an observer; for example, a sensor network monitoring a scientific phenomenon for later play back and analysis. In such networks, the data must be stored in the network. Thus, in addition to battery power, storage is a primary resource: the useful lifetime of the network is constrained by its ab...

In this paper, a load balancing extension for the PVM software system is described. This extension includes slave processes, for obtaining host CPU load information, and a master process for gathering the load information. A programming interface is included to provide the PVM user with CPU load information and a load balancing process spawn. For tested applications , the load balancing extensi...

Currently, mobile ad hoc networks (MANETs) can be deployed in various scenarios but the presence of varying degree of resources, mobility of nodes and the lack of load-balancing capabilities in MANETs (Mobile Ad Hoc Networks) poses a hefty challenge for such networks to scale and perform efficiently when subjected to varying network conditions. Load imbalance is one of the most critical issues ...

Many proposals have been advanced for structured P2P networks, but it is difficult for existing structured P2P networks to achieve dynamic load balancing sufficiently. In this paper, we propose a new structured P2P network called Waon, which achieves dynamic load balancing among nodes. Waon uses a simple algorithm of load balancing and a routing table based on the number of hops between nodes t...

Cloud computing has proposed a new perspective for provisioning the large-scale resources by using virtualization technology and pay-per-use cost model. Load balancing is taken into account as vital part parallel distributed systems. It helps cloud systems improving general performance, better utilization, energy consumption management, enhancing services’ QoS, avoiding SLA violation maintainin...
