Web Service technologies are state of the art in current enterprise distributed applications. To integrate highly resource-constrained devices, such as sensor nodes, into enterprise applications via Web Services, gateways are commonly used. Our aim was to investigate the intermediate, homogeneous communication between enterprise applications and highly resource-constrained devices. We therefore present the prototype implementation of an embedded enterprise compatible W3C Web Service solution. Furthermore, we give an evaluation of memory requirements and a timing analysis for a representative platform with 48 KiB of ROM, 10 KiB of RAM and IEEE 802.15.4 radio. As the prototype implementation requires only 8:5 KiB of ROM and 3 KiB of RAM, our results claim that enterprise Web Services, despite of prevailing assumptions, are feasible in this context. |
