A Multipath Location based Hybrid DMR Protocol in MANET

Abstract

MANET nodes move continuously in a limited area with a random mobility speed. MANET forms a dynamic topology and the nodes only know neighboring nodes if they are within range of the radio. If the nodes are out of range, it is not possible to communicate with this node in the network. Dynamic topology training is also possible in decentralized MANET. The AOMDV routing protocol in MANET establishes several routes between the sender and the receiver. The performance of the multi-route protocol is better than that of the single route protocol. The multiple routes are better by providing multiple routes between the sender and the receiver, but do not retain the location information of the nodes in the network. In this investigation, we proposed DREAM Multipath Routing (DMR) based on the hybrid location in MANET. The DREAM protocol improves the routing performance of multiple routes by maintaining the location information of the mobile nodes. The DREAM protocol reduces the overhead by forwarding packet floods in MANET, which also reduces network delay. The proposed DMR performance is better than normal AOMDV routing. THE DREAM is to keep the location information with the mobility speed of the nodes. The expected possibility of node movement is calculated and flooding of routing packets is also minimized. Package flooding takes place at the intended location of the destination. The position of the number of nodes changes continuously and the DREAM works on each node. Each node stores the location information of all nodes in the neighborhood of the network. The proposed hybrid DMR protocol improves routing performance and offers better data transmission in a dynamic network.
