An interconnection of wired internet and mobile Adhoc network is called integrated internet MANET. This interconnection is achieved through gateways. Gateway may be a fixed gateway or mobile gateway. The gateway works as the router for all the nodes of the MANET through which all the incoming/outgoing packets are routed between the MANET and the internet. Discovery of the efficient internet gat...

This paper reviewed the secure characteristics of mobile devices that can use wireless networks almost anywhere and anytime by using one or more wireless network technologies. These technologies enable the use of infrastructured networks and ad-hoc networks. Further it describes the characteristics o f wireless ad-hoc networks and the environment for the different possible gateway implementatio...

In the existing system, the problem of TCP in MANET’s environment is packet losses induced by network congestion. In case if congestion occurs it leads to the loss of data. In the proposed system, Blue algorithm is used for avoiding packet loss in TCP with wireless network based on checking size of queue. If the size of queue is maximum, gateway directly forwards the packet to destination throu...

The Internet use in mobile has increased day by day .Every user want to access the Internet through mobile phones instead of laptop because of its feature like small in size and portable. When mobile user wants to access the Internet on mobile then all the request goes to the wireless gateway .The gateway acts as intermediate between the two points either it can be from wireless to wired or vic...

In the face of looming IPv4 address exhaustion and the slow pace of IPv4 to IPv6 migration, this work deploys the IPv4/IPv6 translation gateway as a mechanism to ensure most of IPv6 mission critical applications to continuously interoperate with legacy IPv4 nodes. However, the existence of translation gateway between two IPSec nodes from disparate address realms imposes some incompatibility iss...

LoRaWAN is one of the new and updated standards for IoT applications. However, the expected high density of peripheral devices for each gateway, and the absence of an operative synchronization mechanism between the gateway and peripherals, all of which challenges the networks scalability. In this paper, we propose to normalize the communication of LoRaWAN networks using a Reservation-ALOHA (R-A...

ABR is an emerging ATM-based telecommunication service which dynamically allocates bandwidth to the users according to the available bandwidth in the network. However, research shows that ABR-based connections suuer from congestion at LAN-ATM gateway when ATM network abruptly reduces bandwidth available to the gateway. Gateway congestion may result in high packet loss. This article proposes a g...

The Internet Key Exchange Protocol version 2 (IKEv2) is a protocol for setting up Virtual Private Network (VPN) tunnels from a remote location to a gateway so that the VPN client can access services in the network behind the gateway. This document defines an IKEv2 extension that allows an overloaded VPN gateway or a VPN gateway that is being shut down for maintenance to redirect the VPN client ...
