this paper analyses and compares the performances of business-to-business e-commerce data quality and service quality among the use of the ‘push’ and ‘pull’ models. rosettanet’s original partner interface processes use the ‘push’ model which suffers from data redundancy when the volume of business-to-business transaction increases. however, when the ‘pull’ model is used, although it reduces dat...

System reliability analysis and optimization are important to efficiently utilize available resources and to develop an optimal system design architecture. System reliability optimization has been solved by using optimization techniques including meta-heuristics. Meanwhile, the development of meta-heuristics has been an active research field of the reliability optimization wherein the redundanc...

With the trend of SOC technology, high density and high capacity embedded memories are required for successful implementation of the system. In modern SOCs, embedded memories occupy the largest part of the chip area and include an even larger amount of active devices. As memories are designed very tightly to the limits of the technology, they are more prone to failures than logic. Thus, memorie...

in this paper, an efficient fault-tolerant routing algorithm for mobile ad-hoc networks (manets) is presented. the proposed algorithm increases the network fault-tolerance using natural redundancy of ad-hoc networks. this algorithm is carried out in two stages; 1) the selection of backup nodes 2) the selection of backup route(s). in the first stage, the proposed algorithm chooses nodes with the...

Development in the protection scheme highlighting the issues based on two complementary protocols i.e., Parallel Redundancy Protocol (PRP) and High-availability Seamless Redundancy (HSR). These two topologies could mitigate the issue of redundancy to a large extent by building this feature within the protection scheme. It overcomes a link or a switch or a node failure during a zero switchover o...

Vehicular Ad Hoc Networks (VANETs) are considered as a promising scheme to actively guarantee vehicle safety, and broadcast is a key technology for warning message dissemination in VANETs. This paper proposes a novel Position-based Multi-hop Broadcast (PMB) protocol for VANETs in view of some shortcomings of existing broadcast protocols for VANETs, such as ignoring the differences of transmissi...
