Obviously, the energy is one of the important metrics to consider when designing communication protocols for mobile ad hoc networks (MANETs). In this paper, we demonstrate the importance of considering energy saving in MANETs. Our analysis are based on the comparison of two energy-based mechanisms called E-AODV, an energy consumption rate-based routing protocol, and F-AODV, a cross-layer-based routing...
Transporting video over wireless networks has twofold constraints. Not only should it satisfy delay requirements but power minimization and QoS issues should be handled carefully also. Mobile ad hoc networks (MANETs) are more sensitive to these issues where each mobile device acts like a router and thus, routing delay adds significantly to overall end-to-end delay. In this paper, we analyze the performance...
One of the most promising and critical application of vehicular ad hoc networks (VANETs) is improvement of the road traffic safety. Currently there is a growing belief that putting an 802.11-like radio into road vehicles could help the drivers to travel more safely. Although research in this field is in preliminary stage, some simple implementations are quite promising; to the best of our knowledge...
Mobile ad hoc networks (MANETs) are unpredictable by nature. Providing any kind of reliability for quality of service (QoS) in such networks is challenging. Quantifying available resources accurately, avoiding interference with ongoing QoS traffic and adapting to QoS violations caused by nodes' mobility are the main concerns for the design of an efficient admission control protocol in MANETs. Adaptive...
The dynamic nature of the ad hoc networks makes quality of service (QoS) support in mobile ad hoc networks (MANET) a challenging and difficult task where nodes may leave and join the network or move around anytime. A mechanism for resources allocation/reservation has to be implemented to provide the needed assurance for the desired level of quality. Due to the bandwidth constraint and dynamic topology...
End-to-end quality of service (QoS) provision to video-streaming applications over mobile ad hoc networks (MANETs) poses a specially challenging problem. In this paper we propose a cross-layer (XL) network architecture design to optimize the overall performance of video-streaming services over MANETs, called ViStA-XL. The idea relies on applying several optimization strategies to different network...
The cross-layer design approach is an important concept in mobile ad-hoc networks which is adopted to solve several open issues. It aims to overcome MANET performance problems by allowing protocols belonging to different layers to cooperate and share network status information while still maintaining separated layers. While cross-layer model could enhance the performance of the applications and achieve...
Due to resource constraints and dynamic topology of mobile ad hoc networks (MANETs), supporting quality of service (QoS) in MANETs is a challenging task. Although lots of research have been done on supporting QoS in the Internet and other networks, they are not suitable for the MANET environment. While traditional protocol layering is an important abstraction to reduce complexity of network design...
