Mobility protocols are originally proposed to support ongoing Internet connectivity of hosts or networks in motion. However, the requirement of seamless connectivity in mobile environment and use of route optimization between the communicating nodes have introduced several security vulnerabilities to mobility protocols. In this paper, we explain with illustrative examples major security threats on...
This paper is a survey of new and improved recent position based routing methods in Mobile Ad-hoc Networks. The referenced materials agree on the main challenge in creating energy efficient mobile ad-hoc networks. The quest is to realize a simple, yet efficient means of routing and managing the Mobile Ad-hoc Network communications with existing technology. Although many protocols have been proposed,...
Existing wireless networks typically support mobility by routing via a mobility anchor in a home network, but such via routing can result in non-optimized routes. This paper proposes a method to distribute the functions of the mobility anchor to different networks to avoid such non-optimized routes. It proposes a distributed mobility anchors architecture consisting of home mobility anchors (H-MA)...
The aviation community is currently working on the standardization of data communication systems for the future air traffic management. In this context, the ICAO and EUROCONTROL are working on the standardization of IP-based aeronautical telecommunications network and future radio access technologies, respectively. With this work, for the first time, we integrate L-DACS 1, which is one candidate for...
Route optimization for nested Mobile Network is an important issue of Network Mobility (NEMO), and prefix delegation is one of the promising optimization schemes. However, the policy of prefix delegation is seldom discussed when this technology is applied in nested NEMO. The problems that may be encountered when applying the basic prefix delegation to nested NEMO are analyzed and identified, and a...
The 3rd Generation Partnership Project is specifying solutions for IP flow mobility, which enable IP data flows being routed between a mobile terminal and the infrastructure via a 3GPP and non-3GPP access systems, e.g. over LTE and WLAN. Connectivity via the different access systems is provided based on the concept of a shared single Packet Data Network connection. In order to enable IP flow mobility,...
Existing service discovery mechanisms for ad hoc networks are often designed with one specific network type in mind. Solutions capable of handling highly mobile nodes usually have high bandwidth requirements, particularly as the number of nodes increases. The bandwidth requirement can be reduced by locally caching state information, but this increases the risk of nodes having outdated state information...
Wireless backhaul has been received much attention as an enabler of future broadband mobile communication systems because it can reduce deployment cost of pico-cells, an essential part of high capacity system. A high performance network in terms of high throughput, low average delay and low packet loss rate, is highly appreciated to sustain the increasing proliferation in multimedia transmissions...
The current Internet architecture is facing serious scaling problems notably in its routing and addressing system. Also due to the overloaded semantic of the IP address, the current Internet architecture cannot inherently support mobility and multihoming. To solve these problems, different Locator Identity Spilt solutions have been proposed. However most of these solutions tend to focus only on part...
This paper deals with the routing in cognitive mobile ad hoc networks. We propose to modify the widely adopted Ad-hoc On-demand Distance Vector (AODV) protocol in order to assure its functionality in the considered scenario. The resulting protocol, referred to as the Cognitive Ad-hoc On-demand Distance Vector (CAODV) protocol, has been designed according to three guidelines: i) to avoid regions of...
In wireless sensor networks, with respect to a desired time deadline real-time data dissemination schemes achieve that by a spatiotemporal communication approach forwarding data from a source to a destination with a delivery speed. The delivery speed is typically obtained from both the static distance from the source to the destination and the interval of the time deadline. However, in case of real-time...
Micromobility protocols have been proposed to provide seamless local mobility support. There are several micro mobility protocols such as HMIP, Cellular IP and HAWAII. This paper focuses on the performance of single stream forwarding scheme of HAWAII . An analytical model is developed for the evaluation. The aim of the paper is to investigate the impact of the buffering at the old base station on...
At present, many studies focus on the efficiency of handoff among different networks, while research on how to maintain the safety during registration process of handoff is not enough. Unfortunately, mobile node is vulnerable to various security threats and attacks when handover for being lack of protection. A security scheme based on the IPSec protocol which was combined with fast handoff signaling...
In this paper we propose a new architecture for sending, receiving and archiving of multimedia files over 4G MIPV6 network with an effective multiple authentication method. The two modes of mobile multimedia file transfer discussed in this paper are 1) Closed group network suitable for organizations and corporate 2) Peer to peer file transfer between mobile nodes. MIPV6 mobile network enables file...
In this paper we study the problem of message duplication in dissemination of dynamic content such as news or traffic information over a Dense Mobile Social Network (MSN). In MSNs mobile devices disseminate content only to the nodes whose subscribed interest match it. MSNs are used to improve the coverage and increase capacity as we assume that people in an intermittently connected MSNs are socially-related...
In this paper, we consider a 2-hop downlink point-to-multipoint fixed relay systems and propose a novel linear processing strategy at the base station and relay station to improve the reliability of the source-relay and relay-to-destination links. When coupled with a soft-decode-and-forward protocol, the proposed scheme leads to significant performance gain compared to the conventionl solutions for...
In sparse mobile sensor networks, nodes have a small number of neighbors with intermittent connectivity. This paper presents a new networking protocol for this type of network, aimed at maximizing system performance in terms of both delay and reliability. The system is motivated by the observation that many applications on this type of network have two kinds of co-existing data packets: those with...
Most of the work on geocasting has been done for mobile ad-hoc networks and vehicular ad-hoc networks. This paper presents a novel Geocast technique with the hole detection in the geocast region for underwater environment. The proposed model named as Routing and Multicast Tree based Geocasting (RMTG) has been designed for underwater sensor networks. Here we propose a theoretical model for underwater...
The aviation community is in the process of designing the next generation Aeronautical Telecommunications Network (ATN), based on Internet standards, to provide air- ground communications for the aircraft. Support for mobile networks in the current Internet architecture is provided by the NEtwork Mobility (NEMO) protocol. As currently defined, NEMO Basic Support protocol lacks of Route Optimization...
