Enhancing Wireless Meshed Networks with Cooperative IP Header Compression for Parallel Channels

This study presents a cooperative IP header compression approach for wireless meshed networks, addressing multiple channels between terminal and cellular networks. It introduces methods for both single and multiple channel scenarios, emphasizing robustness against channel errors and efficient implementation through cooperative behavior. The proposed scheme showcases advantages such as improved bandwidth efficiency, low memory consumption, minimal complexity, and the ability to operate without feedback channels. This innovation can significantly enhance data transmission in error-prone environments and is suitable for multicasting applications.
