In wireless networks, efficient management of mobility is a crucial issue to support mobile users. The Mobile Internet Protocol (MIP) has been proposed to support global mobility in IP networks. Several mobility management strategies have been proposed which aim reducing the signalling traffic related to the Mobile Terminals (MTs) registration with the Home Agents (HAs) whenever their Care-of-A...
Now a day’s efficient mobility management for mobile users in wireless networking is a crucial issue. To maintain global mobility in IP networking the Mobile internet protocol has been proposed. To reduce the signalling traffic related to the Mobile Terminals (MTs) registration with the Home Agents (HAs), whenever their Care-of-Addresses (CoAs) change several mobility management strategies have...
abstract global financial crisis has created too many problems in relations among governments. among these problems, the issue of global monetary management, more than every time in the past four decades, has been moved in the center of international economic attentions. a problem which is specially known with the monetary hostility between united states and public republic of china. where ar...
abstract: country’s fiber optic network, as one of the most important communication infrastructures, is of high importance; therefore, ensuring security of the network and its data is essential. no remarkable research has been done on assessing security of the country’s fiber optic network. besides, according to an official statistics released by ertebatat zirsakht company, unwanted disconnec...
Personal mobility (PM) is one of key issues in realizing emerging third generation mobile communication systems such as International Mobile Telecommunication 2000 (IMT2000) and it can be realized through universal personal telecommunication (UPT) service. A PM management scheme is considered in order to manage PM information related to UPT users for incall registration/deregistration, incall r...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
The next generation networks must support mobility for ubiquitous communication between any two nodes irrespective of their locations. Mobile IP was the first protocol to support mobility. The process of registration in Mobile IP protocol requires large number of location updates, excessive signaling traffic and service delay. This problem is solved by Hierarchical Mobile IP (HMIP) using the co...
In the vision of pervasive computing, users will exchange information and control their environments from anywhere using various wireline/wireless networks and computing devices. We believe that current protocols, such as DHCP, PPP and Mobile IP, we must be enhanced to support pervasive network access. In particular, this paper identifies three fundamental functions: autoconfiguration, registra...
rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
Personal mobility (PM) is one of the key issues in realizing personal communications service (PCS) in emerging thirdgeneration mobile communication networks such as International Mobile Telecommunication 2000 (IMT-2000). It can be realized through universal personal telecommunication (UPT) service. Two PM management schemes are proposed to manage PM information related to UPT users for incoming...
