The Software Architecture for Efficient Distributed Interprocess Communication in Mobile Distributed Systems

Abstract

The mobile distributed computing applications execute in heterogeneous and dynamic network environments and require efficient as well as reliable interprocess communication (IPC) mechanism. In general, the kernel-level IPC mechanisms offer improved performance as compared to middleware-based systems. This paper proposes the design and implementation of composite software architecture within monolithic kernel to realize high-performance and reliable mobile distributed IPC mechanism supporting mobile computing applications in heterogeneous and dynamic network environments. The performance of software architecture is measured in geographically distributed computing systems executing mobile computing applications. The experimental results illustrate that the proposed software architecture offers significantly improved performance in Ethernet (629 mu s/25 Byte similar to 2929 mu s/5 KB) as well as in wireless networks (34528 mu s/25 Byte similar to 42511 mu s/5 KB). The architecture successfully reduces distributed IPC latency in Ethernet (0.899 mu s/Byte) and in wireless networks (92.628 mu s/Byte). The comparative analysis illustrates that the composite architecture achieves performance enhancements in the range of 12.73 % to 75.84 % as compared to middleware-based IPC mechanisms. The proposed composite software architecture does not require any specific network topology and any specialized communication hardware.
