The Proposed Cluster and Position Based Fault Tolerant Multicast Protocol in Ad Hoc Networks
Mahboobeh Abdoos · 2016
A location service gives the requested location information to the nodes in the ad hoc networks.It is supposed that there are different clusters in the different levels.Every cluster has a cluster head.The clusters can be logical or physical.The higher level cluster heads have the information of the tables of lower level cluster heads.The information of tables of a cluster head is updated periodically by its lower level cluster heads.The combination of the cluster and position based routing can be used.In this paper the cluster and position based location service is represented, that every node can find the location of its destination node via the location service.Some nodes are selected as the mirror nodes of a cluster head which can act as the cluster head after the failing of cluster head.These nodes have the replicated information of a cluster head.Here a multicast protocol is proposed that a source node can get the location information of the destination nodes via the proposed location service and puts this information into the header of packets and sends them toward the destination nodes.The simulation results show that the proposed Cluster and Position based Multicast protocol (CPMB) has more packets delivery ratio and packets transfer ratio than the Multicast Ad hoc On-Demand Distance Vector multicast protocol (MAODV).
