Abstract: The agent based architecture proposed in this paper, is a multi-hop broad cast scheme which is called as Link-Based Distributed Multi-hop Broadcast (LDMB). The existing scheme is a backtracking scheme while the proposed scheme is a forwarding approach which broadcasts emergency messages efficiently in vehicular ad hoc network. The forwarding scheme in LDMB is completely distributed, where each vehicle who receives the emergency message estimates its link status firstly and then computes the waiting time before forwarding this message. LDMB does not need any handshakes and there may be several candidates to forward the message which provides the reliability of the multi-hop broadcast. This paper uses the advantages of LDMB in an agent based environment thereby improving performance of message passing and overcoming the problem of fixed packet size as proposed in the earlier systems.
