Analytical Modelling of Capacity in Wireless Ad hoc Networks

چکیده
In this paper, we propose an analytical model for 802.11 ad hoc wireless networks. Our model consists in replacing a finite number of nodes by an equivalent continuum characterized by a density of nodes and disseminated in the network according to some distribution function. The key feature of the proposed model is that it permits taking into account the effect of interference, the CSMA/CA mechanism and radio propagation aspects in an easy and straightforward way. All assumptions in the model are assessed with extensive simulation results. Closed form formula of the signal to noise ratio and the mean capacity per node will be given, corroborated by extensive simulation results in ns-2.

متن کاملImproving Quality of Service Routing in Mobile Ad Hoc Networks Using OLSR
Mobile ad hoc networks (MANET) are constructed by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. The OLSR protocol is an optimization of the classical link state algorithm. OLSR introduces an interesting concept, the multipoint r...
