A CDMA-based mobile Ad Hoc networks face two main design challenges. One is to periodically update connectivity information, namely, neighboring nodes and the codes used by neighboring nodes. The other is to guarantee that there is no code collision in two hops' distance. This paper proposes an enhanced time-spread broadcasting schedule for connectivity information update. Based on the connectivity information, a code assignment and potential code collision resolution scheme to solve hidden/exposed nodes problem is proposed. Simulation results demonstrate the efficiency and effectiveness of the proposed schemes.
