ABSTRACT: In data message transmissions in wireless multihop networks, intra-route collisions of data messages and control messages are required to be reduced or avoided for shorter transmission delay and higher end-to-end throughput of data messages. RH2SWL (Routing with Hop-by-Hop Shortening Wireless Links) avoids collisions due to the well known hidden terminal problem between 2-hop neighbor intermediate wireless nodes and provides them more opportunities to forward data messages; however, 1-hop neighbor intermediate wireless nodes might forward data messages simultaneously, which causes collisions of data messages. This paper proposes an extension of RH2SWL introducing transmission power control of RTS/CTS control messages and an intentional transmission interval of data messages in order to reduce collisions between data messages and control messages transmitted by 1-hop neighbor intermediate wireless nodes.
