Adaptive Wireless Multi-hop Routing Less Affected by Processing Delay

Abstract

The authors have been proposed a wireless multihop routing method inspired by the behavior of the slime mold. The previous methods iteratively calculate bandwidth allocation for each link based on the maximum bandwidth, the transmission delay, and the required communication volume by the source node. However, the appropriate number of calculation iterations and the actual calculation time for bandwidth allocation vary depending on various factors. In addition, the allocation results cannot be reflected until the calculation is completed, thus the allocation results may not be suitable for the network conditions at the end of the calculation. In this paper, the authors propose an adaptive wireless multi-hop routing with reduced impact of processing delay by sequentially using values that are convergence processes as indicators for route selection.
