In mobile ad hoc networks (MANETs), numerous multimedia applications require quality of service (QoS) support of multicast. This, in turn, requires QoS support of multicast routing. How to design effective QoS multicast routing protocols in wireless Ad Hoc networks is one of the hottest research area accompanied with challenges. Almost all of the QoS parameters are associated with bandwidth. For this...
Recently, because of the rising popularity of multimedia applications and potential commercial usage of MANET(Mobile Ad Hoc Network)s, and the limited bandwidth and dynamic topology in MANETs. providing required bandwidth for these applications in MANETs has become an unavoidable and urgent task to achieve sufficient QoS (Quality of Service). Time slot assignment is essential to provide the calculated...
This paper explores the attributes, layering models and objective functions in cross layer designs for mobile ad hoc wireless networks by taking all the statistical characteristics and constraints from the physical (PHY) layer, media access control (MAC) layer and network (NET) layer into consideration. This paper reviews the entire network optimization across all the PHY/MAC/NET layers. At the PHY...
With the continued increase of speed and capacities of computing devices and the growing needs of people for mobile computing capabilities, Mobile ad hoc networks (MANETs) have gained a lot of interest from the research community. Quality of service (QoS) provisioning in MANETs is an essential component that is needed to support multimedia and real-time applications. On the other hand, directional...
The idea of mobile computing service is to provide a ubiquitous information environment. However, the present mobile ad hoc networks still can't support real-time transmission very effectively. In other words, the capability of supporting QoS guarantee has become a very important issue. IEEE 802.11 PCF adopts the polling scheme to provide time-bounded traffic services, which is not suitable in multihop...
