Abstract:

It is significant to integrate wireless sensor networks,which act as the means to explore and collect environmental information, with open grid comput  ing systems. The combination poses many challenges. This paper analyzes the key requisites of the connection platform which integrates wireless sensor n etworks with the grid. We also design and develop such a connection platform named MPAS. The advantage of MPAS is that it integrates multiple sensor net  works with the grid by utilizing the Web Services resource framework, with the ability to actuate sensor networks and harmonize multiple sensor networks   . The simulation results show that the key factor which affects the MPAS performance is that its notification mechanism is restricted by distributable o perational resources and MPAS supports the communications between multiple sensor networks and the grid well if it is supplied with abundant operational   resources.
