A MAC Protocol for Multihop RP-CDMA Ad Hoc Wireless Networks
RP-CDMA is a wireless multiple access protocol that utilizes multiple spreading codes and a multiple packet receiver to enhance link reliability and performance. The authors apply RP-CDMA to a multi-hop wireless ad hoc network and propose two significant extensions aimed at improving throughput and reliability. Their simulations confirm that RP-CDMA can substantially improve link reliability and network performance, but that a link level acknowledgement protocol is required to ensure packet delivery across the network. They investigate a simple acknowledgement policy and conclude that it enables simultaneous high throughput and packet delivery while maintaining low latency.
