“…One of our goals was to verify if our proposed algorithm was able to reasonably adjust the T parameter under other mobility conditions. With this purpose, in addition to the well-known RWP, the analysis of the proposed algorithm uses other two mobility models: the Manhattan Mobility Model [14] and the Smooth Mobillity Model [15]. The mobility patterns employed are briefly described in the following sections and some properties of them are depicted in Fig.…”

Abstract. The integration of mobile ad hoc networks into IP-based access networks demands the presence of a gateway which is responsible for propagating some configuration parameters by means of Modified Router Advertisement (MRA) messages. This function may be accomplished on demand by the mobile nodes (reactively), periodically activated by the gateway (proactively) or by combining the two approaches. In the proactive mechanisms, the interval of emission of the MRA messages (T ) may significantly affect the network performance. The optimum value for T depends on the network conditions such as the position of the sources, the mobility of nodes, etc. Therefore, an autonomous and adaptive technique to dynamically configure T is strongly recommended. In this sense, a new adaptive gateway discovery mechanism is proposed in this paper. The adaptation is achieved by a control system which has been conveniently configured by means of an analytical model. Simulation results show that the proposed adaptive mechanism improves the conventional proactive schemes.

Abstract. In this paper, we model the epoch distance of the random waypoint model in mobile ad hoc networks. In the random waypoint model, each node selects a target location (i.e., waypoint) to move at a speed selected from an interval. Once the target is reached, the node pauses for a random time and then selects another target with another speed to move again. The movement between two waypoints is referred to as an epoch. In this paper, we derive the probability distribution of the epoch distance for the random waypoint model. Such a study is important as the epoch length distribution may be required for the derivation of the link duration distribution or node spatial distribution for mobile ad hoc networks. The analytical result is then verified via simulation.

“…A number of less and more detailed and accuracy mobility models have been introduced, and adopted in the design and development of mobile ad hoc systems. The survey and discussion of the taxonomies of mobility models and main directions to mobility modeling are provided in [3] and [16]. Generally, the existing mobility models can be classified into two following categories, namely syntactic models: analytical random-motion model -a discrete implementation of Brownian-like motion with randomly generated destination point and velocity, and motion traces models that require the accurate information about mobility patters (i.e., positions of nodes in time).…”

This paper addresses issues concerned with design and managing of mobile ad hoc networks. We focus on self-organizing, cooperative and coherent networks that enable a continuous communication with a central decision unit and adopt to changes in an unknown environment to achieve a given goal. In general, it is very difficult to model a motion of nodes of a real-life ad hoc network. However, mobility modeling is a critical element that has great influence on the performance characteristics of a cooperative system. In this paper we investigate a novel approach to cooperative and fully connected networks design. We present an algorithm for efficient calculating of motion trajectories of wireless devices. Our computing scheme adopts two techniques, the concept of an artificial potential field and the concept of a particle-based mobility. The utility and efficiency of the proposed approach has been justified through simulation experiments. The results of presented case studies show a wide range of applications of our method starting from simple to more complex ad hoc networks.E. Niewiadomska-Szynkiewicz ( ) Institute
