In this paper we propose a design of Application Programming Interfaces (APIs) for configuration of Multi-Robot Sensor Networks (MRSNs). Such networks have unique aspects: intentional mobility and delay tolerance. These aspects limit the applicability of conventional approaches proposed for Mobile Ad-Hoc Networks (MANETs). APIs for configuration of MRSNs must take these aspects into account. In addition, an application program should be transparent from changing of physical devices such as wireless devices. In this paper we describe the design and prototype implementation of APIs for configuration of MRSNs. Delay tolerance: In MANETs, a path from a source to a destination is established when data is transmitted at the source. However, in MRSNs, when data is transmitted at a source node, a path to the destination may not be guaranteed due to disconnection in intermediate nodes. In MRSN, movement is used for data transmission. A certain amount of delay produced by it is permitted.
