Abstract

Abstract:

In Ad hoc networks, a wireless link may be unidirectional because of the difference of transmission range and transmission capability of each node, etc. The features of unidirectional links were studied in Ad hoc networks. A unidirectional link-state advertisement mechanism based on power adjustment (ULAPA) is designed. ULAPA can improve the network connectivity. According to ULAPA, a unidirectional link-state advertisement mechanism based on accurate power adjustment (ULAAPA) is proposed. ULAAPA can decrease energy consumption of nodes through accurate power adjustment. A routing method using unidirectional links is described for Ad hoc network. Results of simulation show some performances are better than those of traditional routing mechanisms.

Key words: Ad hoc network, unidirectional link, power adjustment, advertisement mechanism
