Abstract: Routing in Mobile Ad hoc Networks (MANETs) is a challenging task due to the dynamic nature of the network topology and resource constraints. Due to communication over wireless channel, participating nodes also experience interference and bandwidth constraints. Therefore it is essential to develop a robust and efficient routing protocol for MANETs. This research paper involves design and development of a multipath routing protocol for MANETs, called Load Sharing Multipath Routing (LS-MPR) uses dual polarized directional antenna to enhance network efficiency and provide load balancing. LS-MPR is an on-demand multipath routing protocol, which selects best possible multiple paths based on ascending order of hop count and availability of common polarization between neighboring mobile nodes. The performance of the LS-MPR is compared with that Ad-hoc On Demand Distance Vector (AODV) and Dynamic Source Routing (DSR). The network performance is checked with and without node mobility, throughput, Packet Delivery Ratio (PDR), least jitter, low interference and low end-to-end delay. Directional antenna is a very efficient and low cost smart antenna technology. It can achieve better performance, higher throughput, and better resource utilization with omnidirectional antennas multi-path routing cannot be exploited very well since packets routed on one of the paths cause an interference zone that typically encompasses the other paths and thereby limits the number of packets routed on these paths
