چکیده |
On-Demand Multicast Routing Protocol (ODMRP) is a
well-known protocol for ad hoc networks. This protocol is
mesh based and exhibits a high packet delivery ratio even
at high mobility. In ODMRP the robustness is achieved by
using the number of multiple routes which is a solution for
the high speed mobility and the subsequent route breaking.
The ODMRP is such designed that the number of multiple
routes only depends on the number of senders and
receivers, irrespective of the node speed and the traffic
load. In this paper we proposed a Reduced Data
Transmission ODMRP (RDTODMRP) routing algorithm
that considers the network conditions e.g. mobility speed
and traffic load to determine the multiple routs. This cuts
down the unnecessary redundant routes and their data
transmissions. Furthermore in ODMRP and RDTODMRP,
flooding of Join-Request packets causes excessive control
overhead, In order to solve the problem, we Limit some
nodes to Flood Join-Request packets and forbid it to be a
forwarding node (LF-RDTODMRP). It is shown by
simulation that the RDTODMRP and LF-RDTODMRP
reduce the number of data transmission, control overhead,
end to end delay and improve the data packet delivery
ratio. |
