“…Specifically, we set = = 100 m and = 60 m. In addition, the distance from to 0 is 95 m and that from to 0 is 155 m. The density of simultaneously activated vehicles on each road is set to be the same, that is, = , ∀ , ∈ Z, and is denoted by . Unless otherwise specified, the rest of network parameters are listed in the Table 1, most of which are adopted from [5,18,19].

“…Compared with the I2V links from to and to , the path loss exponent for the V2V -link may be smaller due to the relative shorter distance and simpler fading characteristics between them. For instance, following [18,19], we can choose = = 4 and = 2. For other choices of the path loss exponents, the analytical method provided in this paper can also be applied.…”

We investigate the information transmission in a typical communication scenario in the intelligent transportation systems (ITS), that is, infrastructures providing ITS services that intend to broadcast independent messages to the vehicles within their coverage areas. Due to the dynamic nature of wireless signal propagation links and interuser interference, it is hard to guarantee satisfactory performance by direct infrastructure to vehicle (I2V) transmissions. To solve this problem, we propose allowing certain vehicles to serve as relays to assist in the information distribution process and applying a class of finite-field network codes to efficiently use the available spectrum resources. Considering that the infrastructure information sources and all vehicles are randomly distributed following Poisson point processes, we model a general urban ITS communication network and based on the stochastic geometry we derive the probability that a vehicle can successfully recover all the desired messages from its serving infrastructure. The analytical and numerical results clearly demonstrate that our proposed network coding based relay-assisted I2V transmission can significantly improve the communication performance of the conventional direct I2V transmission strategy.

“…Authors in [3] conclude that the locations of the transmitters in 802.11p tend to be a PPP, and use PPP to approximate the performance in the dense scenario. Works in [3] is extended in [4], where the authors consider both sparse, middle and dense cases, and approximate the coverage probability by a modified matern hard core point process. Reliability of the vehicles near intersections is evaluated in [5].…”

Abstract-Vehicular network can improve traffic safety by exchange of safety-related messages between the vehicles within the the neighborhood of each other. However, many research related to vehicular network depends heavily on system-level simulation. In this paper, we use tools from stochastic geometry to analyze the reliability of the transmission of periodic message in a highway scenario. A Poission point process (PPP) basedbased network and slotted-aloha MAC scheme is assumed. Three-slope pass loss and rayleigh-lognormal fading are taken into consideration. Coverage probability and packet reception rate (PRR) are adopt as the reliability metrics. We then derive the closed form expressions of coverage probability and PRR. Finally, the accuracy of the analysis is validated via simulation.

“…Nguyen et al [11] modeled the interferences under carrier sense multiple access with collision avoidance (CSMA/CA) in dense IEEE 802.11 networks using a Matern point process, which ensures the distance between any two selected nodes is greater than a carrier sense range. Tong et al [12] proposed an extended Matern point process to model IEEE 802.11p for vehicular ad hoc networks where the backoff counter takes discrete and non-uniform distribution within the backoff window. However, the Matern point process presents several flaws regarding the modeling of transmitters in a CSMA/CA network, as it cannot estimate the CSMA/CA networks in certain situations [13].…”

Abstract-Inter-user interference occurs when multiple body sensor networks (BSNs) are transmitting simultaneously in close proximity to each other. Interference analysis in BSNs is challenging due to the hybrid medium access control (MAC) and the specific channel characteristics of BSNs. This paper presents a stochastic geometry analysis framework for inter-user interference in IEEE 802.15.6 BSNs. An extended Matern point process is proposed to model the complex spatial distribution of the interfering BSNs caused by the hybrid MAC defined in IEEE 802.15.6. We employ stochastic geometry approach to evaluate the performance of BSNs, considering the specific channel characteristics of BSNs in the vicinity of human body. Performance metrics are derived in terms of outage probability and spatial throughput in the presence of inter-user interference. We conduct performance evaluation through extensive simulations and show that the simulation results fit well with the analytic results. Insights are provided on the determination of the interference detection range, the BSN density, and the design of MAC for BSNs.Index Terms-inter-user interference, body sensor networks, stochastic geometry, medium access control.
