Abstract-The paper proposes a MAC layer protocol called Qo-applied in the MAC protocol. Also, many contention-free MOR (QoS-aware MAC protocol using Optimal Retransmission) multiple access schemes investigated in, for example [2], do that is designed to provide QoS in a decentralized network with not work in this setup. Our goal is to develop a de-centralized multiple sensor (source) nodes that do not have the capability MAC.to receive acknowledgements from the sink node. A minimum protocol-to p enQoS ranTees f bhatime-tial data delivery probability between the sensor and sink nodes is and non time-critical sensor readings. This is a challenge that achieved by allowing each source node to transmit each new has not been adequately addressed by any existing approach.packet an optimal number of times in every interval of time. TheThe most important metrics to analyze the QoS performance paper first discusses the single QoS class case and derives the of any MAC protocol are throughput, latency and delivery maximum achievable frame delivery probability and then extends . . the concepts to the multiple QoS class case. It also addresses a few probability. However for the wireless ilntra-vehcular sensor design optimization criteria. Simulation and numerical analysis network that we are considering, we will focus on the frame results show that QoMOR can effectively provide QoS guarantees delivery probability as the metric. This is because the traffic under distributed control without using conventional ARQ-based load is fixed (as each sensor generates one frame of a fixed schemes.size every T units of time) and usually low (e.g., 32 bits every 1 ms per sensor). Also, the latency of a successfully delivered I. INTRODUCTION frame is bounded by T (as a frame that cannot be success-The current automotive sensor networks are wired systems. fully delivered within T is simply dropped). Accordingly, the A normal vehicle may have more than a hundred sensors and resulting throughput in the network can be calculated based switches. Driven by the safety and environmental issues such on the product of the delivery probability and the traffic load as the need for stability and emission control, more sensors while the latency is randomly distributed in the interval (0, T]. are being added to vehicles [1]. The wiring harness of the In this paper, we have designed a MAC protocol and studied sensors contributes to at least 60 lbs of normal vehicle weight. its performance assuming that the wireless intra-vehicular To reduce the vehicle weight and the cost of wiring harness, sensor (WIVES) nodes belong to either single or multiple QoS it is desirable to replace signal wires by wireless links. To classes with different delivery probability requirements but design an optimal wireless intra-vehicular sensor network, it is share the single communication channel. The study shows that, critical to investigate medium access control (MAC) protocols given requirements of a minimum network size of 100 nodes so that the performance with respect to lat...

This paper reports on a real-world wireless channel measurement campaign for in-vehicle scenarios in the UWB frequency range of 3 to 11 GHz. The effects of antenna placement in the vehicle's passenger compartment as well as the effects due to the presence of passengers are studied. The measurements have been carried out in the frequency domain, and the corresponding channel impulse responses (CIRs) have been estimated by inverse Fourier transform. The influence of a specific band group selection within the whole UWB range is also given. Statistical analysis of the measured channel transfer functions gives a description of the wireless channel statistics in the form of a generalized extreme value process. The corresponding parameter sets are estimated and documented for all permutations of antenna placement and occupancy patterns inside the vehicle's passenger compartment. Further, we have carried out a feasibility study of an in-vehicle UWB-based localization system based on the TOA. The positioning performance is evaluated in terms of average error and standard deviation.
