Wireless Ad-Hoc Networks (WANETs) need algorithms and protocols that may provide higher packet delivery throughput for non-structured networks with a high degree of mobility. Moreover, the possibility of reducing the broadcasting packages that will heavily consume power resources on nodes is extremely important. This paper studies the implementation of a modification in the epidemic algorithm, a direction-biased Gossip associated with a Quorum system applied into LAR routing protocol in a fault scenario of an ad-hoc network. The simulation results show that the new association decreases the number of energy consumption without degrading the message delivery ratio.
