Abstract:

In order to overcome the shortcomings of traditional EJB, CORBA, and publish/ subscribe middleware software architecture, an efficient software component framework suitable for embedded dis- tributed computing environment is proposed. The software architecture is based on the open service gate- way initiative(OSGi)standard, and can be used in multi-communications protocol environment by adding a transmission abstraction layer. It is characterized by versatility, high stability and less memory foot- print. The experimental results show that the software is superior to the traditional software architecture in memory footprint, startup time and service interface response time. It can meet the harsh conditions of the embedded environment.

Key words: computer software, computer architecture, software architecture, embedded, component- based, open service gateway initiative
