Design and implementation of heterogeneous wireless gateway

This study proposed a software-based heterogeneous wireless gateway (HWG) to achieve the integration of multiple heterogeneous wireless networks. In an HWG, received packet is temporarily saved with buffer. And then a packet format conversion mechanism is adopted to enable packet under different wireless network protocols be converted to appropriate formats. Therefore, when the transmission demand occurs, the source nodes and destination nodes at both ends of heterogeneous wireless network can mutually communicate information via this gateway without changing the original communication protocol of each network, based on the modulization design to support multiple communication interface and system extensibility.
