We propose a cross-layer approach for supporting the quality of service (QoS) of bidirectional real-time applications in IEEE802.11 DCF WLANs. In the proposal, the class-based queueing with the priority queue (PQ) scheduler is exploited in network layer ...

In this paper, we propose a secure and efficient key establishment scheme designed with respect to the unique requirements of Wireless Mesh Networks. Our security model is based on Identity-based key establishment scheme without the utilization of a ...

Current pervasive systems tend to consider security and QoS separately, ignoring the influence of each aspect on the other. This paper presents an adaptation model based on selection of component compositions enabling to capture dynamic and fine-grained ...

This paper proposes a new HCCA scheduling scheme for AFDX (Avionics Full DupleX switched Ethernet) traffics on IEEE 802.11e Wireless LAN (WLAN). The AFDX requirements are related to the temporal constraints (end-to-end latency and jitter). Our ...

In a wireless network, open and wireless communication channels set the restriction of wired connections free, because wireless signal acts as the platform of data transmission. On the other hand, the open and shared nature of wireless networks also ...

In this paper, we are conducting a probabilistic analysis of the energy consumption of nodes of a wireless sensor network caused by the use of MAC layer protocols, to know which one is best suited to save energy. Representative examples of duty-cycled ...

The spectrum of licensees can be shared by some secondary users in cognitive radio systems. However, the secondary transmitters are limited by an interference threshold constraint which is imposed by the primary receivers in order to ensure primary ...

Applications over wireless sensor networks are growing quickly. Traditional software development tools are not well adapted to this technology. In particular, adequate testing methodologies are required. Many issues have not been formally addressed as ...

Popularity of Wireless Sensor Networks (WSNs) combined with the multimedia requirements of new applications have enabled Wireless Multimedia Sensor Networks (WMSNs) which commonly carry heterogeneous traffic. In order to deliver multiple types of ...

Typical sensor nodes are resource constrained devices containing user level applications, operating system components, and device drivers in a single address space, with no form of memory protection. A malicious user could easily capture a node and ...

In building automation IP based network infrastructures aim to reduce facility management costs remarkably by allowing multiple applications to use the one communication network at the same time. This open approach requires a secure and confidential ...

In recent years, the considerable progress of miniaturization and the consequent increase of the efficiency of digital circuits has allowed a great diffusion of the wireless sensor network technology. This has led to the growth of applications and ...

We present SEGURA, a Bundle layer security extension for ensuring the authenticity and integrity of message bundles in Delay Tolerant Networks (DTNs). SEGURA employs probabilistic set membership constructs to amortize the cryptographic functionality of ...

In the last few years RFID technology widespread. This technology can be found in each field of our daily life, e.g. supply-chain management, libraries, access management etc. For the sake of small computational capacity of RFID Tags, at first, only ...

In this paper, we modify and extend the P2PSIP's leading draft (RELOAD) in order to both adjust its operation better with respect to the properties of wireless ad hoc networks and improve the provided security level. In terms of security, a public/...
