    An adaptive policy routing with thermal field approach
    (9th International Conference On Innovative Internet Community Systems I2CS 2022, 2009) Lertsuwanakul, Lada-On; Unger, Herwig
    This paper introduces an adaptive routing approach based on buffer status and distance in a mesh overlay network: Thermal Field is used for considering buffer stage and distance is applied to select routing policy. The path selection process considers the Thermal Field as a metaphor for the buffer usage based on probability in order to avoid message loss by overloaded peers or delay because of big queues, otherwise routing by the shortest way. In addition, the probability of Thermal Field consideration relies on leftover distance to the target instead of using a global constant. The experiment results substantiated our approach using the adaptive probability of routing mechanism works effectively.

    Fuzzy logic based routing in grid overlay network
    (10th International Conferenceon Innovative Internet Community Systems (I2CS) – Jubilee Edition 2010 –, 2010) Lertsuwanakul, Lada-On
    With the aim to improve the quality of service of the modern distributed application, we propose a multi-criteria routing algorithm running in a mesh structured overlay network. Using a grid pattern can improve routing remarkably, since it provides alternative and partly disjunctive paths of equal length as well as the ability to measure distances between nodes in the overlay network. A Thermal Field approach is used to represent buffer stages on the nodes. The decisionmaking algorithms use fuzzy logic techniques to select the optimal path considering multiple constraints. The proposed algorithm is evaluated using P2PNetSim, a network simulation tool. The approach is compared to Shortest Path routing and probability functions using deterministic or adaptive approach. The result of routing with fuzzy logic shows superior routing performance than others both in delivery ratio and routing time.
