The Node Distribution of the Random Waypoint Mobility Model for Wireless Ad Hoc Networks
This article considers a generalization of the random waypoint model in which the pause time of the mobile nodes is chosen arbitrarily in each waypoint and a fraction of nodes may remain static for the entire simulation time and derives an exact equation of the asymptotically stationary distribution for movement on a line segment and an accurate approximation for a square area.
Computationally efficient scheduling with the physical interference model for throughput improvement in wireless mesh networks
This paper presents a computationally efficient heuristic for computing a feasible schedule under the physical interference model and proves, under uniform random node distribution, an approximation factor for the length of this schedule relative to the shortest schedule possible with physical interference.

The notion of shareability network is introduced, which allows to model the collective benefits of sharing as a function of passenger inconvenience, and to efficiently compute optimal sharing strategies on massive datasets, and demonstrates the feasibility of a shareable taxi service in New York City.
The Critical Transmitting Range for Connectivity in Sparse Wireless Ad Hoc Networks
The critical transmitting range for connectivity in wireless ad hoc networks is analyzed and insight into how mobility affects connectivity is yielded and useful trade offs between communication capability and energy consumption are revealed.

This paper proposes a distributed transmit power control method based on a strict fairness criterion, i.e., distributed fair power adjustment for vehicular environments (D-FPAV), to control the load of periodic messages on the channel and proves the fairness of the proposed approach.
Comparison-based system-level fault diagnosis in ad hoc networks
A new comparison-based diagnostic model based on the one-to-many communication paradigm is introduced and the ability of diagnosing faults under this scenario is significantly reduced with respect to the stationary case.
Revisiting Street Intersections Using Slot-Based Systems
Results theoretically show that transitioning from a traffic light system to SI has the potential of doubling capacity and significantly reducing delays, which suggests a reduction of non-linear dynamics induced by intersection bottlenecks, with positive impact on the road network.
Investigating upper bounds on network lifetime extension for cell-based energy conservation techniques in stationary ad hoc networks
This paper investigates the lifetime/density tradeoff under the hypothesis that nodes are distributed uniformly at random in a given region, and that the traffic is evenly distributed across the network and shows that even in this low density scenario, cell-based strategies can significantly extend network lifetime.
Social-aware stateless forwarding in pocket switched networks
SANE is the first forwarding mechanism that combines the advantages of both social-aware and stateless approaches in pocket switched network routing, based on the observation that individuals with similar interests tend to meet more often.

The results can be used to improve the accuracy of RWP mobile ad hoc networks simulation, which is commonly used to evaluate the performance of ad hoc networking protocols, and provide a better understanding of the behavior of a fundamental network parameter in the presence of mobility.
