In this paper, we model energy harvesting wireless sensor network (EH-WSN) as geometric random graph with energy dependent edges. Then we propose an algorithm for investigating path connectivity and packet delivery ratio between source to sink in EH-WSNs and conventional WSNs. From the results obtained by running our proposed algorithm, we can see that path connectivity and packet delivery ratio of EH-WSN always outperform those of conventional WSN, especially when node’s density is low. However, these differences do not change much as node’s transmission range varies.
