Abstract

This paper proposes a new spreading code protocol (GBCR protocol) suitable for ad hoc DS/CDMA wireless data networks, which is co-ordinated by a central station (CS) that tracks user's status. Users are divided into groups, each of which is assigned a 'group-based common' (GBC) code used by transmitters in the group to acquire the current state of their targets from the CS. Data communication is allowed only after a positive ACK packet from the CS is received, so that all successful terminals are effectively sheltered by the CS from third-party colliding packets, which are encoded by the same receiver-based code. Analytical results reveal that the GBCR protocol can improve network stability and throughput-delay performance, while still keeping the hardware as simple as possible.
