Throughput analysis for IEEE 802.11 ad hoc networks under the hidden terminal problem

Industrial wireless sensor network (IWSN) applications are required to provide precise measurement functions as feedback for controlling devices. Current industrial wireless communication protocols, such as ISA100.11a and wirelessHART, have difficulty, however, in guaranteeing latency for unpredictable on-demand communications. In this paper, a priority-based dynamic multichannel transmission scheme is proposed for IWSNs. In the proposed scheme, a root node controls the transmission timing of high-priority packets, while other nodes autonomously decide what channel to use and when to transmit packets to a neighbor. Simulation results show that real time control is possible where a response delay from transmission of a request to reception of a reply at a root node is within 1,140 ms at per-link communication success probability with a retry of higher than 93%.

“…Note that the channel utilization is considered to be the percentage of time in which useful information is transmitted in the wireless medium. Firstly, we give a brief overview of the model presented in [5] and then we proceed to estimate the channel utilization effect of the exposed terminals. Figure 3 depicts a conventional IEEE 802.11 ad hoc network where the nodes' transmission range is r and the wireless channel data rate is R. Let now consider the node A of Figure 3.…”

Abstract. The paper evaluates the performance effects of exposed terminals in IEEE 802.11 ad hoc networks in finite load conditions. In this context, employing also models from previous authors' work, the paper derives analytical models for the estimation of channel utilization and media access delay for IEEE 802.11 ad hoc networks in finite load conditions with and without exposed terminals. The simulation results show that the analytical estimated channel utilization and media access delay metrics are fairly accurate.

SUMMARYThe hidden-terminal problem significantly degrades the performance of IEEE 802.11 DCF. Many previous works have investigated its influence on the throughput of CSMA-based medium access control (MAC) protocols, especially IEEE 802.11 DCF. In this paper, we introduce a new Jamming problem for IEEE 802.11-based mobile ad hoc networks, which is caused by hidden terminals. An analytical model is established for this problem. Based on this model, an adaptive DCF (ADCF), is designed to solve the jamming problem through adaptively adjusting the minimum contention window of hidden terminals. Simulation results effectively demonstrate that the proposed A-DCF can avoid the jamming and in turn greatly improve channel utilization and throughput.
