Abstract
Device to device Communication is a very impressive method of communication as it does not need any pre exiting expensive communication infrastructure. Devices (nodes) themselves perform all the network operations such as routing. Such types of networks are very useful in areas where communication infrastructure is not available or it was destroyed by some kind of mistake. A mobile Ad-hoc network is a network of this class. In a MANET routing is done by nodes themselves and there are several methods available in the literature of routing. Reactive routing is a technique in which routes are recorded only if they are needed. AODV is most popular reactive routing protocol of mobile ad hoc network. In this paper we are presenting a novel concept of route selection “SMART” in which stochastic multi-criteria acceptability analysis method is used to find the best route for transmission of packet from source to destination. This acceptability method is a branch of multi-criteria decision method (MCDM), and it has flexibility to assign importance to different criteria and the same can be change according to the situation in which the network is being used. The proposed scheme is implemented on NS-2 Platform and compared with other noteworthy research papers for verification of improvement in performance.
Highlights
In real world there may exist situation in which communication facility is needed in the areas where communication infrastructure is not installed or it was destroyed
Minimum Hop Count ensure that the route is shortest but there are some other factor which must be considered at the time of route selection
In ad hoc network, when a node needs to communicate with some other node which is out of its direct transmission range, the node must relay on its neighbors to deliver the packets
Summary
In real world there may exist situation in which communication facility is needed in the areas where communication infrastructure is not installed or it was destroyed. In ad hoc network devices(nodes) communicate with each other either directly or with the help of forwarding chain system(FCS). In FCS intermediate nodes cooperate with neighbors by forwarding their packets intended for others. Cooperation of nodes is a key issue in designing routing methods for ad hoc networks. Routing protocol is a binding agent in the network which ensures the delivery of packets from source to destination. Reactive routing method reduces the overhead since route are not searched when there is nothing to transmit. AODV searches all the routes from source to Destination and in the case of multiple routes, the route with minimum Hop Count(HC) is selected for transmission of packets. Minimum Hop Count ensure that the route is shortest but there are some other factor which must be considered at the time of route selection
