Generating Realistic Node Mobility and Placement for Wireless Multi-Hop Network Simulation
There exists a considerable number of node placement models and algorithms for simulation of wireless multihop networks. However, the topologies created with the existing algorithms do not have properties of real networks. We have developed NPART (Node Placement Algorithm for Realistic Topologies) in order to resolve this fundamental issue in simulation methodology. We compare topologies genera...
متن کاملA Hidden Node Aware Network Allocation Vector Management System for Multi-hop Wireless Ad hoc Networks
Many performance evaluations for IEEE 802.11distributed coordination function (DCF) have been previouslyreported in the literature. Some of them have clearly indicatedthat 802.11 MAC protocol has poor performance in multi-hopwireless ad hoc networks due to exposed and hidden nodeproblems. Although RTS/CTS transmission scheme mitigatesthese phenomena, it has not been successful in thoroughlyomit...

متن کاملFlow Demands Oriented Node Placement in Multi-Hop Wireless Networks
In multi-hop wireless networks, flow demands mean that some nodes have routing demands of transmitting their data to other nodes with a certain level of transmission rate. When a set of nodes have been deployed with flow demands, it is worth to know how to construct paths to satisfy these flow demands with nodes placed as few as possible. In this paper, we study this flow demands oriented node ...
متن کاملNPART - node placement algorithm for realistic topologies in wireless multihop network simulation
Despite a considerable number of topology generation algorithms for simulation of wireless multihop networks it is difficult to find one with output similar to real networks [13]. In this paper, we propose NPART – a Node Placement Algorithm for Realistic Topologies whose created topologies resemble networks encountered in reality. The algorithm is flexible since it is sufficient to provide it w...
