摘要：MANETs are characterized by dynamic multi-hop topologies in which the nodes can move arbitrarily, changing the topology rapidly depending on the scenario. This results in traffic flows and service times that do not necessarily follow a Poisson or exponential distribution. Additionally, partitioning/merging of traffic and non-independent service distributions make a mathematical analysis based on queuing theory infeasible [1]. Consequently, the performance evaluation in this work is based on simulations. This paper presents the simulation environment and simulation results for the evaluation of the proposed QoS algorithms. SED performance evaluation scenario considers only real-time traffic. Although a majority of today network traffic is mixed (non real-time and real-time), this real-time traffic only scenario is used in order for the results to clearly reflect the performance benefits of SED for real-time traffic compared to other existing algorithms. In the current literature, new QoS service architectures have been proposed for IP-based networks that classify the traffic into multiple classes using Multi Protocol Label Switching (MPLS). In these service architectures, each service class implements a QoS scheme like FIFO or RED [2, 3]. Therefore, having only real-time traffic in the performance evaluation of the SED algorithm is not a simplification but rather a valid assumption for such architectures.
