The Effects of Network Density of a New Counter-based Broadcasting Scheme in Mobile Ad Hoc Networks

Broadcasting is an essential operation in mobile ad hoc networks (MANETs) to transmit the message (data packet) from the sender to all other nodes in the network. Flooding is the simplest mechanism for broadcast operations, where each node retransmits every uniquely received message exactly once. Flooding is usually costly and results in serious redundancy, contention and collisions in the network. These problems referred to as the broadcast storm problem. Counter-based broadcasting scheme has been introduced to solve the problems in flooding. This study introduces a new counter-based broadcasting scheme to achieve efficient broadcasting by using the counter-based scheme with dynamic threshold to increase the reachability percentage of the transmission packets which receive the broadcast message to all nodes with high reachability and increase the throughput of the network by using ns-2 simulations. The simulation results show that the new scheme provide good results in performance levels by taking in consideration the status of the node density like sparse and dense areas.
