Performance Analysis Of Broadcasting In Mobile Ad Hoc Networks Using Cluster Approch

Broadcasting is a fundamental service in Mobile Ad hoc Networks (MANETs). Cluster based approach are proposed in literature to reduce the network collision, to reduce delay of packet transmission, to reduce the energy consumption and improves the throughput. In this paper, a cluster- based infrastructure is proposed for broadcasting in MANETs. The backbone of the network takes advantage of the cluster structure and only requires cluster- heads and some selected gateways to forward the broadcast packet. Each cluster head selects some gateways to forward the packet when it sends the packet to all the cluster heads in its coverage set. Cluster structures have been simulated using mobile simulator Glomosim 2.03, which gives better performance to reduce the network collision, to reduce delay of packet transmission, to reduce the energy consumption and improves the throughput.
