In this article, the authors develop an `analytical closed-form expression` for the outage capacity of a wireless ad hoc network. First, a series of practical modulation schemes including binary phase shift keying (BPSK) and quadrature amplitude modulation (QAM) are considered. Then, a proper formulation for the total network capacity is presented based on the cumulative distribution function (CDF)...
In this paper we develop analytical closed form expression for the capacity of a wireless ad hoc network. First, for the general case when nodes can adapt their communication rates to the link quality, a proper formulation for the total network capacity is presented based on the cumulative distribution function (CDF) of the signal to interference power ratio (SIR). Then, a closed form expression for...
The total amount of capacity that can be obtained from a network is an essential performance metric. However, in wireless ad hoc networks, the dynamic topology and stochastic variations in channel characteristics, makes it difficult to analytically determine this metric. In this paper we develop analytical closed form expression for the network capacity. First the cumulative distribution function...
The authors employ a statistical method to characterise the wireless ad hoc network capacity problem. The channel parameters such as path loss and fading are considered in the analysis. Moreover, a simulation method based on the probability density function of signal-to-interference-plus-noise power-ratio is introduced. In both analysis and simulation, two receiving methods, matched filter (MF) and...
In this paper we propose a traffic isolation method to be used in cluster-based broadcasting algorithms. For internal broadcast traffic, cluster-heads and gateways are responsible for re-broadcasting but for external ones, border nodes may perform the forwarding function as well. This simplifies the gateway selection method through the local selection of gateway nodes by its cluster head. This reduces...
A cluster-based flooding algorithm for wireless ad hoc networks has been proposed. This mechanism uses a novel gateway usage approach. Dividing the flooding traffic to internal and external from each cluster point of view, gateway selection is just needed for the internal traffic. This simplifies the gateway selection method as well as improving the flooding performance parameters. The stability-based...
