In networks where nodes are aware of their locations via the use of a GPS receiver or other localization techniques, geographic routing has been suggested to be the candidate of choice for robust and resource efficient routing. However, efficient location management algorithms are required for the source node to obtain the destination node’s location before it can start data transfer using geog...

In the recent decade, special attention is paid to reverse logistic due to economic benefits of recovery and recycling of used products as well as environmental legislation and social concerns. On the other hand، many researches claim that separately and sequential planning of forward and reverse logistic causes sub-optimality. Effective transport activities are also one of the most important c...

A geography-based grid location service (GLS), proposed elsewhere, has resulted in a scalable location management service for mobile ad hoc networks (MANETs) where packet forwarding decisions are based on geographic position. A similarly scalable location management strategy has been devised for MANETs that employ hierarchical link state routing. Both approaches employ hierarchical principles ...

Position-based routing is a promising technology for VANET. And location service is the fundamental component for the success of position-based routing. A map-based location service algorithm is proposed in this paper. It uses a predesigned hash function to map a node to a certain location, where location servers are recruited. Hence any node in the network can find location servers of others, ...

Data traac in networks has always been dominated by le transfers, an observation that has motivated previous work in scheduling le transfers. While these previous research contributions address le transfers, they do not address the special considerations required of packet-switched networks, in particular the issues of routing and of simultaneous transmissions of les. In this paper, we generali...

Routing performance is critical for Peer-to-Peer (P2P) systems to achieve high performance. Current routing algorithms concentrate on creating a well organized network architecture to boost routing performance. However, for each routing procedure, system returns location information of the requested file only and the characteristics of system workload are seldom considered. In this paper, we pr...

This study extends a mathematical model that integrates the location, allocation, inventory replenishment and routing decisions simultaneously. To cope with inherent uncertainty of parameters, we implement a continuous-time Markov process and derive the performance measures of the system. Using the obtained results, the problem is formulated as a mixed integer nonlinear programing model (MINLP)...

In this paper, a stochastic analysis method is proposed for extraction and evaluation of power distribution map (PDM) in system printed circuit board (PCB). This conducted based on some system-level information including placement routing geometry, network (PDN), component package parasitic, voltage regulator module (VRM). A simple model supply current two constituent blocks electronic systems ...
