An efficient broadcast relay scheme for MANETs
چکیده انگلیسی
This paper focuses on the upper bound of broadcast coverage area to achieve high delivery rate and low number of rebroadcasts. In order to improve the performance of geometry-based protocols, a novel relative position-based broadcast relay (RPBR) approach is proposed, in which the forwarding hosts are able to rebroadcast packets effectively, especially for heavy host density. The numerical results show that the proposed RPBR scheme is able to enhance the distance-based protocol to rebroadcast packets effectively by increasing the packet delivery ratio up to 10%. On the other hand, for the angle-based protocol associated with RPBR, the number of forwarding hosts can be reduced by 30%. A performance comparison of the topology-based broadcast protocols and the RPBR scheme combined with geometry-based in dynamic ad hoc network environment is presented.
