Bandwidth Allocation and Routing Information for Wireless Mobile Ad-hoc Networks

An admission control Algorithm must organize among flows and should afford assurance of how the medium is shared between nodes. In a wired network, nodes can keep an eye on the medium to see how much bandwidth is being used by the network. On the other hand, in an Ad-Hoc network, during communication nodes possibly will use the bandwidth of neighbouring nodes. Consequently, the bandwidth consumption of flows and the accessible resources to a node are not local concepts, other than it being linked to the neighbouring nodes in carrier-sensing range. Current solutions do not address how to perform admission control in such an environment so that the admitted flows in the network do not exceed network capacity. Here I present an application to demonstrate how the bandwidth is shared between nodes and the effectiveness of admission control framework to support QoS in Ad-Hoc networks

Performance metrics for the prediction of link and path availability in VANETs

In this paper metrics are produced which may be used for performance enhancement in Vehicular ad-hoc networks (VANETs) protocols. The method described makes use of the concept of link availability estimates which are produced on an individual link basis and which may be combined by multiplication to produce a quality metric for the whole route. The technique is discussed in the context of the Ad hoc On-demand Distance Vector (AODV) routing method
