The Internet of Things is rapidly diffusing, though severe modifications are needed to the current Internet architecture to cope with its new requirements. A major step forward is decoupling the name of an object (identifier) from its physical location (locator), which are both expressed by the IP address currently. We argue that additional advantages can be brought if context metadata are provided...
The growing demand for ubiquitous computing lead manufactures to develop multi-band devices supporting different network access technologies, such as GSM, Wi-fi, and UMTS. Although these devices support different access technologies, they lack of native vertical handover support, breaking any ongoing connections whenever users switch between access technologies. In this paper we present a next-generation...
In this paper, the issue of mobility and roaming in Pay-TV systems are studied to propose the novel multidomain universal service delivery architecture to provide legitimate subscribers with a ubiquitous access to multimedia services. The paper also considers other cooperating IP/Mobile and Broadcast architectures to add flexibility and mobility in service provisioning to a certain geographical area...
In order to ensure ubiquitous connectivity, networks have to operate in regions with very limited infrastructure support. There has been intense recent research activity in the emerging areas of intermittently connected, ad hoc, and delay/disruption tolerant networks (DTN). DTNs differ greatly, depending on the nature of the network environment; they range from deep space networks to buses driving...
Most solutions focus on the home network security server management and gateway device certification. It is unrealistic where the most subjects are mobile users who want to control home network devices. Therefore minor and fast certification structures are needed to control other devices with mobile device that has lower computing capacity. To solve the above problems, this paper wants to build safe...
The proposed architecture is structured into a secure API, a backbone, and separate device networks with standard interface to the backbone. The API decouples innovation of services and service logic from protocols and network elements. It also enables service portability between systems, i.e. a service may be allocated to end-systems or servers, with possible relocation and replication throughout...
With the increasing demand of ubiquitous computing, the interconnection of mobile ad hoc networks (MANETs) to Internet is also getting attractive, which is so-called hybrid or connected MANET. In MANET paradigm, routing is a challenging task due to mobility and the resulting inherent dynamic network topology. In many applications, multipath routing scheme is favorable than single-path routing due...
Many small devices are capable of connecting to the Internet now. The trend of pervasive computing and networking is going strong. At the same time, security threats on the Internet continue to increase. Existing defense mechanisms against network-based attacks can hardly apply to small network devices due to limitations of their computing resources. This paper presents a method to mitigate this problem...
