Abstract
Mobile Ad Hoc Network (MANET) is a multi-hop wireless network in which fixed infrastructure is not used. A single-path routing protocol is mainly proposed as a single route from source node to destination node, while a multipath routing protocol uses multiple routes from the source to the destination node. This paper evaluates the performance of single-path routing protocols which are Cluster Based Routing Protocol (CBRP) and Ad hoc On-demand Distance Vector (AODV) along with a multipath routing protocol which is Ad hoc On-demand Multipath Distance Vector routing (AOMDV) in MANET environments with varying node densities (Dense and Sparse). Network Simulator (NS2) was used to evaluate the performance of these routing protocols. Our experimental simulation results show that: AOMDV protocol is better than AODV and CBRP in terms of Delay for both Dense and Sparse topologies with variant traffic sources, whereas AODV is better than CBRP and AOMDV in terms of Packet Delivery Ratio (PDR) with all traffic sources in Sparse topology. Keywords: MANET, Routing Protocols, Node Density, Single path and Multipath.

This paper evaluated the performance of single-path (CBRP and Ad hoc On-demand Distance Vector (AODV)) and multipath (AOMDV) MANETs routing protocols in both Dense and Sparse network topologies
The experiment simulation results show that in Dense topology Ad hoc On-demand Multipath Distance Vector routing (AOMDV) protocol is better than both AODV and Cluster Based Routing Protocol (CBRP) in terms of Delay at different traffic sources, and that AOMDV has better Packet Delivery Ratio (PDR) with 40 sources
Summary
A Mobile Ad hoc Network (MANET) is a group of wireless mobile nodes that connect with another without using any existing network infrastructure. This paper evaluates the efficiency of single-path routing protocols (CBRP and AODV) along with multipath protocol (AOMDV) in MANET topology with difference node densities (Dense and Sparse). AODV (Perkins., Belding-Royer, & Das, 2003) is an on-demand routing protocol that allows dynamic and multi-hop routing among mobile nodes that are needed to form and Performance evaluation of single-path and multipath manets routing protocols for dense and sparse topology maintain MANETs. AODV is principally a combination between of DSR and DSDV (Destination Sequenced Distance Vector) protocol. As in any another hierarchical routing protocols, there are routing overheads that are in connection with cluster creation and maintenance It is because some mobile nodes can carry varying topologies data due to the long broadcast (Abolhasan et al, 2004). A 250 m sets as transmission range to each node using the Two-Ray Ground Propagation model
