A new efficient medium access control protocol for multi-hop wireless mesh networks

This paper presents a new medium access control (MAC) scheme, which exploits the code division multiple access (CDMA) technology to provision many-to-one simultaneous wireless communication service without utilizing any time division multiple access (TDMA) scheme. This, combined with existing one-to-one (i.e., unicast) and one-to-many (i.e., multicast or broadcast) wireless communication services, brings into life a new communication paradigm, that is, mesh communications. The new scheme also supports accumulative receptions, namely, a receiver can buffer partially damaged (re-)transmitted frames and add those frames efficiently to form an error-free frame. Our simulation results show that the new scheme outperforms IEEE 802.11 in both non-mobile and mobile environments.
