| Summary: | Mobile ad hoc networks (MANETs) are consists of mobile devices connected
wirelessly. MANETs communicate without any fixed infrastructure or any centralized
domain. All the nodes are free to move randomly within the network and share
information dynamically. Routing protocol in MANET show how the mobile nodes
messages are forwarded in a multi-hop fashion. The wireless connectivity and node
mobility in MANET networks contributes in rapid topological changes, which brings the
need for a channel aware routing protocol. Hence, the need for efficient routing
protocols to allow the nodes to communicate. In such a communication scheme a routing
protocol play an important role in the network performances. Achieving high user data
rates over multi-hop wireless paths is considered the ultimate goal for MANET. To
overcome this problem, several important modifications to the routing protocol
algorithms are then considered to operate better in networks. This research work
proposed a SNR-based routing metric for Dynamic Mobile Ad hoc Network onDemand
(DYMO) routing protocol. This paper starts by investigate and compare the performance
among reactive routing protocols in MANET. Secondly, the DYMO protocol choose
routes based on SNR metric are modeled as proposed the new routing metric.
Simulations scenarios are used for the work of the research by develop the new routing
metrics in DYMO protocol module in OMNET++. The results show that SNR-DYMO
improves the performance of the MANET in terms of throughput and packet delivery
ratio throughout all simulation scenarios. |
