The Domain Name System (DNS) is used almost everywhere in mobile networks to determine the IP addresses of the network elements and thanks to the DNS architecture of the inter-operator IP backbone network, a network element of a public mobile network (PMN) can easily determine IP addresses of any other PMN. The analysis of some customers' complaints showed that it could be the cause of billing mistakes...
Currently, we can observe the growing of the use of mobile devices as a media for both Internet access and carrying out purchase and sale of products and services. Commonly, E- commerce platforms are enabled by either proprietary systems or by buying ads on specialized websites. This scenario involves the adoption of strategies based on e-commerce servers, which represent a non-scalable strategy....
WiFi sharing communities are an interesting option for mobile Internet access. Today, however, users need to give up privacy in exchange for connectivity: they are required to expose their identity in order to be granted access. This information can be used to track users and to generate usage and movement profiles. We identify the challenges of providing a maximum level of privacy and anonymity in...
Mobile Ad hoc Networks (MANETs) are formed by collection of, potentially mobile, portable devices without established infrastructure. In such networks, connectivity is established through IP addresses and dynamic routing. MANETs are highly dynamic with frequent nodes joining and departure. Due to this node dynamicity, the node's IP address changes frequently. Therefore, to enable and run common user...
Wireless sensor networks (WSNs) have many applications in home and industrial automation, and the management and integration of WSNs into Internet and IP-based networks is still getting tremendous interesting. This paper presents a micro SOA-model as part of a 4-layered, SOA-based architecture targeting resource-constrained devices with 48 KB of ROM and 10 KB of RAM. The key idea in this model is...
Proxy mobile IPv6 (PMIPv6) is designed to provide a network-based localized mobility management protocol, but it does not handle the global mobility of hosts. In this paper, we propose a location management scheme based on domain name system (DNS) for PMIPv6. In this proposed scheme, DNS as a location manager provides PMIPv6 for global mobility. In addition, a paging extension scheme is introduced...
The third generation network which is vigorous nowadays will be followed by an all-IP infrastructure referred to as Next Generation Networks (NGN) in the near future. More specifically, the IP Multimedia Subsystem (IMS) is the only standardized way to offer IP based services that are enabled by one common core and all types of access networks and devices. The heterogeneity and mobility of the IMS...
The domain name system (DNS) is a cornerstone for the Internet and the most globally deployed Internet service that provides user-friendly naming for Internet hosts. DNS is a distributed data base that allows convenient storing and retrieving of resource records. Recently an interesting feature was added to BIND implementation of the DNS system to support secure dynamic updates. In this paper, we...
The Domain Name System (DNS) is an existing and implemented network service in Internet providing host and service reachability, which is essential to every IP connection setup. Merge of mobile networks with Internet results in large flow of frequent updates to the DNS database, which is a threat for DNS database consistency, because of strong caching it uses. Even though DNS wasn't originally designed...
The current trend towards convergence of telecommunication and data networks considering all emerging access technologies is leading to more heterogeneous and dynamic environments. Networking visions are evolving towards ubiquitous computing and it is foreseeable that once users start to establish their own networks formed by their personal devices, the number of both mobile networks and mobile nodes...
Domain name system (DNS) maps domain names to IP addresses in the Internet. DNS can, however, be used as a location manager (LM) for mobility management in wireless mobile networks. The suitability and performance of DNS as a LM for locating mobile hosts (MH) has not been studied in the past. In this paper, we develop an analytical model to measure the performance of DNS as LM for IP diversity based...
