Recent Developments on Mobile Ad-Hoc Networks and Vehicular Ad-Hoc Networks

This book presents collective works published in the recent Special Issue (SI) entitled "Recent Developments on Mobile Ad-Hoc Networks and Vehicular Ad-Hoc Networks”. These works expose the readership to the latest solutions and techniques for MANETs and VANETs. They cover interesting topics such as power-aware optimization solutions for MANETs, data dissemination in VANETs, adaptive multi-hop broadcast schemes for VANETs, multi-metric routing protocols for VANETs, and incentive mechanisms to encourage the distribution of information in VANETs. The book demonstrates pioneering work in these fields, investigates novel solutions and methods, and discusses future trends in these field

Cross-layer design gains in MANETs

In this paper we propose and implement cross-layer network design models with three different MAC protocols: CSMA-CA, CSMA-CA with RTS/CTS, and ALOHA. These network models are used to study the behavior of Cross-Layer Designs (CLDs) in case of dynamic network topologies with different transmission ranges and network sizes. A similar network model but with a conventional Oblivious Layered Design (OLD) is also implemented to compare the performance of the cross-layer models and to show the impact and potential benefit of cross-layering. Our results show that the CLD gain is comparable to the gain that results from selecting a better MAC protocol. The results also show that CLD, unlike OLD, fully utilizes the link capacities and its gain is proportional to the average number of the session hops
