With respect to the specific characteristics of VANETs, the proposed routing protocol adopts a dynamic topology establishment and time-varying control message sending mechanism. A direction-based forwarding strategy and a specific warning solution enhance the routing performance in ARPP. Simulation results show that the ARPP protocol outperforms the classic AODV in urban vehicle environment.展开更多

It is necessary to interpret the consciously capturing process of the knowledge that is formed unconsciously. Storytelling is important in the capturing and conveying of tacit knowledge.

文摘After presenting weaknesses of several classic routing protocols applied in vehicular ad hoc networks (VANETs) by a qualitative comparison, this paper proposes a novel self-adaptive routing protocol, named ARPP. With respect to the specific characteristics of VANETs, the proposed routing protocol adopts a dynamic topology establishment and time-varying control message sending mechanism. A direction-based forwarding strategy and a specific warning solution enhance the routing performance in ARPP. Simulation results show that the ARPP protocol outperforms the classic AODV in urban vehicle environment.
文摘The relative difficulty of capturing and conveying knowledge is determined on the diversity of knowledge types. It is necessary to interpret the consciously capturing process of the knowledge that is formed unconsciously. Storytelling is important in the capturing and conveying of tacit knowledge. Culture, structure, system, and the knowledge holders within the organization also affect the transfer of personal knowledge.
