For wireless mesh networks using the IEEE 802.11 family of standards, carrier sensing mechanisms such as physical carrier sensing and virtual carrier sensing play a key role in determining goodput and overall network performance. However, inaccurate modelling of the effect of carrier sensing on goodput leads to poor decision making in mesh network roll out. More accurate models can be derived by analysing...
Contending flows in multi-hop 802.11 wireless networks compete with two fundamental asymmetries: (i) channel asymmetry, in which one flow has a stronger signal, potentially yielding physical layer capture, and (ii) topological asymmetry, in which one flow has increased channel state information, potentially yielding an advantage in winning access to the channel. Prior work has considered these asymmetries...
The aim of this paper is to use analytical means to discover the effective functional range of a node in Wireless Mesh Networks (WMNs) and to determine the optimized position of the relaying node when placed between two mesh routers in WMNs. A simple source to destination model with two transmission distance schemes and simple relaying node model with three relaying node position schemes were designed...
