“…A simple approximate model of the preamble contention was developed in [26]; in contrast to our model, the approximate model [26] does not explicitly consider the backoff nor the limited number of transmission attempts. A simplified model of LTE connection establishment was represented through a G/G/1 queue in [27].…”

The connection establishment in Long-Term Evolution Advanced (LTE-A) is often executed for distributed user equipment (UE) nodes with frequent small data sets for transmission to the central enhanced Node B. LTE-A connection establishment consists mainly of an access barring check (ABC) followed by preamble transmission (contention). Previous studies of connection establishment have often assumed Poisson characteristics (without verifying the Poisson assumption). In this paper, we introduce a simple equilibrium analysis framework for comprehensively evaluating the LTE-A connection establishment, including both access barring and preamble contention. We conduct a detailed analysis of the backlog arising from the uniform backoff over up to T max o slots by UE requests that failed the barring check or collided in the preamble contention. We verify that the process representing the numbers of backlogged UE requests rejoining the connection establishment tends to Poisson process characteristics for high barring probability and long maximum timeout T max o . We present numerical comparisons of our equilibrium model with simulations for practical parameter settings. The comparisons illustrate the effects of the parameter settings on the convergence of the LTE-A connection establishment dynamics to Poisson characteristics for nonsynchronized and synchronized request arrivals. Index Terms-Access barring check (ABC), backlog model, Long-Term Evolution Advanced (LTE-A), Markov modulated poisson process, Poisson process, preamble contention, uniform backoff.

“…In this section, we study stability of multiple-loop NCSs with shared multi-channel communication networks subject to the constraint (8), and the introduced threshold-based decentralized scheduling policy (7). We show stochastic stability of the overall networked system by the notion of Lyapunov stability in probability (LSP).…”

“…Thus to obtain boundedness of error state, we need to look at an interval of time-steps rather than only one transition step such that, given the channel capacity constraint (8), all sub-systems have non-zero chances of transmission. Therefore, one can infer that an interval of length…”

Control over shared communication networks is a key challenge in design and analysis of cyber-physical systems. The quality of control in such systems might be degraded due to the congestion while accessing the scarce communication resources. In this paper, we consider a multiple-loop networked control system (NCS), where all control loops share a communication network. Medium Access Control (MAC) is performed in contention-based fashion using a multi-channel slotted ALOHA protocol, where each control loop decides locally whether to attempt a transmission based on some error thresholds. We further introduce a local event-based resource-aware scheduling design with an adaptive choice of the error thresholds for a transmission. This leads to a hybrid channel access mechanism where the control loops are deterministically categorized into two sets of eligible and ineligible sub-systems for transmission in an event-based fashion, before a random process to select the available channels. In addition, employing the introduced policy, we show the stability of the resulting NCS in terms of Lyapunov stability in probability. We illustrate numerically the efficiency of our proposed approach in terms of reducing the average networked-induced error variance, and show the superiority of the adaptive event-based scheduler compared to the scheduling design with non-adaptive thresholds.

“…To investigate the RACH contention situation resulting from M2M, 3GPP has provided protocol-level evaluations in [4]. A more detailed delay and energy analysis as well as simulation of RACH performance for overloaded M2M scenarios can be Manuscript found in [5]. Some RACH overload resolution protocols for LTE-A have been summarized in [6].…”

Network access for M2M/H2H hybrid systems: a game theoretic approach

Long Term Evolution-Advanced (LTE-A) is prospering as one of the promising mobile communication systems. In the near future, it is expected that in addition to traditional humanto-human (H2H) communications, an LTE-A system needs to support many applications with the technique of machine type communications (MTC), or machine-to-machine communications (M2M). Since M2M features a large number of devices, a mechanism to guarantee the performance of H2H and M2M in the random access procedure of LTE-A (RACH procedure) should be considered. However, little research provides dynamic RACH resource allocation approaches for H2H and M2M. In this paper, we propose a game-theoretic framework, which divides its random access resources into three groups: for H2H, for M2M, and for the hybrid usage. Under this framework, the Nash Equilibrium (NE) guarantees the system throughput by adaptively redistributing the traffic loading, and the NE can be approached rapidly even if the information of traffic loading is quite limited.Index Terms-RACH procedure, random access, game theory, mixed strategy Nash Equilibrium.
