The wireless channel-oriented ad-hoc multi-hop broadband (W-CHAMB) is a new link layer protocol with the aim of being able to support quality of service (QoS) in multi-hop operation in fully distributed ad hoc networks. It is based on time division multiple access (TDMA) technology, operating on a single frequency channel. In this paper, we improve the prioritized access mechanism by inserting the...
In this paper, the queueing performance of an adaptive type-I hybrid automatic repeat request (ARQ) with a generalized Markovian source is studied for a TDMA/TDD system over a Markovian channel. In the adaptive type-I hybrid ARQ of our interest, the pay load size for information in a packet (or ARQ block) and the coding rate of ARQ block vary, according to the channel state, e.g., high coding rate...
In this paper, we study the problem of scheduling real-time traffic in wireless TDMA channels. Specifically, we propose scheduling schemes that dramatically improve the delay performance of individual flows, while at the same time provide fairness and quality of service (QoS) guarantees. Previous works in this area have overlooked one or more of these aspects, so our study is both novel and valuable...
