TLDR
A new, realistic model of node motion based on the movement of vehicles on real street maps is presented, which is compared with the Random Waypoint mobility model, the most widely used mobility model.Abstract:
Without realistic modeling of node mobility, simulation evaluation of performance of mobile ad hoc networks may not correlate well with performance in a real deployment. In this work, we present a new, realistic model of node motion based on the movement of vehicles on real street maps. Our model can be used with the ns-2 network simulator. We compare our model with the Random Waypoint mobility model, the most widely used mobility model. Results show that, in many ways, the Random Waypoint mobility model is a good approximation for simulating the motion of vehicles on a road, but there are situations in which our new model is better suited.read more

Modeling mobility with behavioral rules: the case of incident and emergency situations
TL;DR: A new modeling approach to mobility is proposed, namely Behavioral Mobility models (BM), which decomposes mobility into simple atomic individual behaviors that yield realistic displacement patterns by reproducing the mobility observed at small scales in every day life, in both space and time.

The Broadcast Storm Problem in FANETs and the Dynamic Neighborhood-Based Algorithm as a Countermeasure
TL;DR: It is proved that broadcast storm problem causes network contention as the number of UAVs increases but also proposed the innovative dynamic neighborhood-based algorithm for the broadcastStorm problem (DNA-BSP), which was developed and validated based on the outdoor experiments and computer simulations and outperforming classical broadcast storm mitigation techniques when applied in FANETs.

Task dissemination with multicast deluge in sensor networks
Xiao Zheng,B. Sarikaya +1 more
TL;DR: An analysis of various message costs as well as the overall cost of data messages is presented and how the performance will be impacted by various parameters in a sensor network with mobile sensor nodes is shown.
Cooperative attack and defense in distributed networks
TL;DR: A number of attacks which exploit cooperation to devastating effect are described, and a more radical alternative called suicide is described: a good device removes a bad one unilaterally by declaring both devices dead, and suicide and voting to revocation in vehicular networks are applied.

Dynamic Source Routing in Ad Hoc Wireless Networks.
David B. Johnson,David A. Maltz +1 more
TL;DR: In this article, the authors present a protocol for routing in ad hoc networks that uses dynamic source routing, which adapts quickly to routing changes when host movement is frequent, yet requires little or no overhead during periods in which hosts move less frequently.
