Interference of links in wireless mesh networks has a great impact on the network performance. Most of previous studies of this problem are based on unrealistic interference models which in some cases lead to erroneous results. In this paper, based on realistic physical interference model we give a full classification of interference cases for two links, provided that stations composing these links...
CSMA/ECA is a modification of CSMA/CA that delivers higher performance by reducing the number of collisions. This paper presents an algorithm to adapt a configuration parameter of the protocol to ensure high performance for any given number of competing stations. Performance is measured in terms of efficiency and fairness. The proposed algorithm has been tested by means of simulation to show that...
We propose TBSP, a TDMA protocol for gathering information periodically from multiple data sources to a central location across multiple hops. TBSP incurs a lower overhead than the existing protocols because it only requires the sensor nodes to keep track of their own schedule, whereas in the existing protocols each node needs to know the schedule of its neighbors. In order to gain a transmission...
