Abstract
Multicast group communication over mobile ad hoc networks has various challenges related to secure data transmission. In order to achieve this goal, there is a need to authenticate the group member as well as it is essential to protect the application data, routing information, and other network resources etc. Multicast-AODV (MAODV) is the extension of an AODV protocol, and there are several issues related to each multicast network operation. In the case of dynamic group behavior, it becomes more challenging to protect the resources of a particular group. Researchers have developed different solutions to secure multicast group communication, and their proposed solutions can be used for resource protection at different layers i.e. application layer, physical layer, network layer, etc. Each security solution can guard against a particular security threat. This research paper introduced a self-organized hash based secure routing scheme for multicast ad hoc networks. It uses group Diffie-Hellman method for key distribution. Route authentication and integrity, both are ensured by generating local flag codes and global hash values. In the case of any violation, route log is monitored to identify the malicious activities.
Highlights
Multicast based communication is a vital network service, which sends the data from a source to multiple destinations simultaneously by creating copies only when the links to the destinations split
Multicast routing tree can be constructed to transmit the data from the sender to all the destinations with a minimum multicast tree cost that is used to evaluate the utilization of network resources [1]
Shared Keys are used for node Identification purpose, called authentication which may be quite timeconsuming process and its performance depends upon the number of keys to be processed and the number of participants involved in group communication [29][30][31[32]
Summary
Multicast based communication is a vital network service, which sends the data from a source to multiple destinations simultaneously by creating copies only when the links to the destinations split. Multicast routing tree can be constructed to transmit the data from the sender to all the destinations with a minimum multicast tree cost that is used to evaluate the utilization of network resources [1]. Multicast packets are transmitted to all members of a group with the same reliability as regular unicast packets. Multicasting can reduce the cost of communication, consumption of bandwidth, sender and router processing and delivery delay [2]
