In multi-hop wireless networks, the source and destination nodes usually have some candidate paths between them, and the path quality depends on the selection of a multi-hop path from these candidates. Therefore, it is important to choose a high quality path. Also, the theoretical analysis of the relation between the selection of a path and the quality of the path is important to evaluate the performance of networks. In this paper, we use ETX (expected transmission count) as a metric of path quality and analyze the ETX of the best path, which maximizes the communication quality. We approximately analyzed the ETX of the best path in a one-dimensional network where nodes are randomly distributed because the exact analysis is difficult in such a network. Then in this paper, we derive two theorems to exactly analyze the ETX of the best path in the network where nodes are located at constant intervals. Theorem 1 gives ETX of the best $k$-hop path, which maximizes the communication quality in all $k$-hop paths. Theorem 2 limits the number of hops of the best path to at most two candidates. We compute the ETX of the best path using Theorems 1 and 2, and compare a path which minimizes the length of each link and another path which minimizes the number of hops with the best path in the ETX. |
