This paper presents a Model of Quality of Service (QoS) for Next Generation Networks (NGN), that consist of a tower of five defined layers such as the Model Layer of QoS, Control of Admission, QoS in the Routing, QoS in the Signaling, and MAC QoS. In addition, the model raises a method based on the concept of segregation of functions defining two functional networks along with the tasks of QoS. Then,...
Providing quality-of-service (QoS) in wireless adhoc networks is an intrinsically complex task due to node mobility, distributed channel access, and fading radio signal effects. This goal can be successfully accomplished only through the cooperation of the different protocol layers involved. In this paper we propose a novel QoS architecture that is able to support applications with the bandwidth,...
This paper presents a preliminary design of Geo-MAC, a MAC protocol that exploits spatial diversity in highly mobile wireless networks. It aims to achieve low latency and high reliability, goals that are intrinsic to the success of many envisioned vehicular safety applications. Conventional MAC layers address reliability through ARQ mechanisms that re-transmit messages from the source, if earlier...
