Abstract
(type = abstract)
Relaying cooperation in wireless ad hoc network has been studies for years. Through relaying cooperation, nodes can communicate with other nodes that are not in their communication range. However, because relaying packets costs extra resources of intermediate nodes, certain nodes may refuse to cooperate for saving own resources, especially when a network doesn’t belong to a fixed infrastructure, such as wireless ad hoc network. Thus, to change the behavior of those selfish node, certain systems are proposed to stimulate the relaying cooperation. These systems are popularly classified as reputation-based system and pricing-based system. Three pricing-based strategies based on different key variables are proposed in this thesis. To evaluate the effectiveness of these strategies in terms of the equality of chances to participate in cooperation, a new fairness index named centrality fairness is proposed. By studying the behavior of nodes in static and dynamic topologies, edge node issues and importance of node mobility are discussed. With sufficient results from experiments, these pricing-based strategies are proved to be effective in static topology, and all of them can alleviate the effect from edge node issues. Eventually, the strategy using utility ratio as the key variable of the pricing adjustment is concluded to be the best strategy, which can provide the best centrality fairness of a designated static network. Finally, to study the contributions of other parameters, such as pricing refresh rate ([pi symbol]) and step size of pricing adjustment ([delta symbol] ), several experiments are done with these parameters fine-tuned.
