| Abstract: | Transmission reliability is one of the important indexes reflecting the performance of wireless sensor networks (WSN). Aiming at the issue that the nodes' failures affect the stability and reliability of the data transmission, a multi-paths and erasure encoding based reliable transmission strategy (MPE2S) is presented. According to the normalized values of the ants' pheromone produced in best-worst ant system which reflect the quality of links, multiple disjoint paths for data transmission are established between the nodes with the adjacent hierarchies. The erasure-coded data packets from the source data is to be allocated to and transmitted through the multi-paths by the load balance mechanism to realize the fault tolerance. Theoretical analysis and simulations show that MPE2S has a higher receiving rate and accuracy rate of the data packets and energy efficiency. It has the good performance of fault tolerance, stability and reliability of data transmission. |
