As we are moving toward the next generation all-IP wireless networks, we are facing the integration of non-homogeneous networks, such as wireless wide area networks (WWAN) and wireless local area networks (WLAN). In vertical handoff between WWAN and WLAN, the mobile hosts are required to be able to move freely across different networks while satisfying the quality of service requirements for a ...

thirty five monoconidial isolates of the fungal culture collection pyricularia grisea were examined, to identify the vegetative compatibility groups and characterize the genetic diversity of isolates as through rep-pcr genomic fingerprinting. the isolates were collected from ricefields during 1997-1999. genetic diversity of p. grisea isolates was studied as based on dna fingerprinting through r...

Abstract— Peer-to-Peer ( P2P ) systems have been the center of attention in recent years due to their advantage . Since each node in such networks can act both as a service provider and as a client , they are subject to different attacks . Therefore it is vital to manage confidence for these vulnerable environments in order to eliminate unsafe peers . This paper investigates the use of genetic ...

The routing and signaling protocols for supporting multipoint-to-multipoint connections in ATM networks have been presented earlier. VP-Merge and VC-Merge techniques have been proposed as the likely candidates for resolving the sender identification problem associated with these connections. The additional buffer requirements in the VC-Merge mechanism and the excessive use of VPI/VCI space in t...

Logistics Network Design includes network configuration decisions having long-standing influences on other tactical and operational decisions. Recently, regarding environmental issues and customer awareness and global warming closed-loop supply chain network design is taken into consideration. The proposed network for the integrated forward and reverse logistics is developed by formulating a cy...

We introduce a methodology for establishing a connection between two arbitrary nodes of a multiclass broadband network that secures suucient resources at every intermediate node along the selected route, and thereby guarantees quality of service (QOS). We describe how a Virtual Path (VP) mechanism may be implemented within our framework, and compare the performance achieved by such a scheme wit...
