Enhanced Broadcasting and Code Assignment in Mobile Ad Hoc Networks
Jinfang Zhang, Zbigniew Dziong, Francois Gagnon, Michel Kadoch
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. Full Text
