Multipath routing protocols provide improved throughput and route resilience as compared with singlepath routing protocols. However, multipath routing mechanism has not been explored thoroughly in the domain of mobile ad hoc network for overhead and complexity. In this paper, we analyze and compare on-demand singlepath and multipath routing with IEEE 802.11 DCF in mobile ad hoc network, in terms of Routing overhead and MAC overhead. The results reveals that in comparison with singlepath routing protocol, multipath routing mechanism creates more overheads but provides better performance in congestion and capacity provided that the route length is within a certain upper bound which is derivable. The analytical results are further confirmed by simulation.
