Unmanned control vehicles are used for a variety of scenarios where the user can conduct a task from a remote location, scenarios include surveillance, disaster recovery and agricultural farming. The operation of unmanned vehicles is generally conducted over a wireless communication medium. The nature of the wireless broadcast allows attackers to exploit security vulnerabilities through passive and...
Wireless sensor networks (WSN) are highly distributed self-organized systems, the associated research being growing at a tremendous pace, and targeting various application domains. The successful implementation of such networks is dependent on the enabling technologies (such as digital electronics and wireless communications), as well as the provisioning of Quality of Service (QoS) and various security...
Non-repudiation techniques are to ensure any communication taking place between two or more parties will be undeniable. Therefore it is crucial to include digital signatures of the involving parties while the communication is taking place. In medical practices, involved parties may include patient(s) and doctor(s) who are involved in series of visits, diagnosis, prescription, possible operation, and...
This paper treats BWA (Broadband Wireless Access) implementation in TK (Telecom of Kosova) NGN network in its efforts to keep the leading position in Kosovapsilas competitive telecommunication market. At the beginning, the architecture of TK NGN network with its corresponding elements is described. Such standard-based, open architecture core network enables the integration of Voice and Multimedia...
This paper proposes a fast forward medium access control protocol (FFMAC) for quality-of-service (QoS) guarantee in multihop IEEE 802.11s wireless mesh networks with multiple channels. To the best of our knowledge, the proposed protocol is the first one which considers the multihop and multichannel issues simultaneously. It provides higher priority for real-time applications, while remaining the distributed...
