A hotspot offers Internet access over Wi-Fi through the use of a router connected to a link to an internet service provider. If the link is wireless, e.g., WiMAX, the hotspot becomes mobile. Under such a heterogeneous network, it is challenging to provide QoS and/or to control data rate. In this paper, we design and implement a policy server for commercial WiMAX mobile hotspots based on Policy ...

— This paper presents a low-cost proposal for the development of a remote laboratory, offering the possibility of providing learning in the field of robotics for users with no need to be physically in the laboratory, or simply not having to take the robotic platform to reprogram it, also giving the option of working with the same platform to a group of users to test their algorithms by turns. T...

This paper is devoted to researching the routing reliability and router standby mechanism for smart and cooperation network. The method of updating and initiating the standby router has been also provided. With the aid of virtual interface, both the main router and standby router will be transparent to the network. Through Mini-Net simulated experiment, this paper has verified the mechanism. It...

Status of this Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. This document reflects an existing deployed protocol. The IETF does have a working group which is in the process of producing a standards track protocol to address the same issues. Abstract The memo specifies the Hot Standby...

Financial inclusion (FI) is an aspect of risk inherent in financing where this Islamic law that applied mudharabah and musyarakah contracts. Its application can be done through the derivation RBT with portfolio theory, from second it produces a strategic agility diversification investment (SADI) proposition. To able to improve financial performance FIs form challenge facing, benefits, realizati...

‎A module $M$ is called FI-extending if every fully invariant submodule of $M$ is essential in a direct summand of $M$‎. ‎It is not known whether a direct summand of an FI-extending module is also FI-extending‎. ‎In this study‎, ‎it is given some answers to the question that under what conditions a direct summand of an FI-extending module is an FI-extending module?

the ip lookup process is a key bottleneck in routing due to the increase in routing table size, increasing traıc and migration to ipv6 addresses. the ip address lookup involves computation of the longest prefix matching (lpm), which existing solutions such as bsd radix tries, scale poorly when traıc in the router increases or when employed for ipv6 address lookups. in this paper, we describe a ...

as technology scales deep into the nanometer regime, on-chip communication becomes more susceptible to transient noise sources, such as crosstalk, external radiation, and spurious voltage spikes. the network on chip s modularity and reusability has brought about the use of error control methods to address transient errors in network on chip links.in this work, we design a fault tolerance router...

T-Mobile has a service called “Wi-Fi Calling”, which lets users make and receive calls even when without cellular service. This service is pre-installed on millions of TMobile Android smartphones. We analyze the security aspects of this service from a network perspective, and demonstrate a man-in-the-middle attack caused by a lack of TLS certificate validation, allowing an attacker to eavesdrop...
