Scrutiny of broadcasting efficiency with and without clustering in Manet
B. Gomathy, D. Sathiya · 2017
A node disseminates a message to all other nodes in the wireless adhoc network through broadcasting this is the basic requirement for broadcasting protocol. Clustering the nodes for broadcasting in mobile ad hoc networks plays a vital role in improving resource management and network performance (routing delay, bandwidth consumption and throughput). The clustered architecture of a mobile ad hoc network (MANET) has the virtue of keeping the node information locally which is suitable for scalability. The broadcast storm problem can be avoided by reducing broadcast redundancy through clustered network also can save scared resources bandwidth and energy. A non-clusterheads node just relays the broadcast packet if it is selected as a forward node or else it does nothing. The clusterheads and forward node sets can broadcast. The efficiency of broadcasting with and without clustering has been studied based on throughput, delivery ratio and delay through various simulation results gathered.
