An Efficient Routing of TORA Protocol with Clustering Technique in MANET

The field of Mobile Adhoc Network (MANET) has become very popular because of the deep research done in that area in last few years. MANET has advantage of operating without fixed infrastructure and also it can tolerate many changes in the network topology. The MANET uses different routing protocols for End to End Packet delivery. This paper is subjected to the Reactive routing protocols on the basis of identical environment conditions and evaluates their relative performance with respect to the performance metric Packet delivery ratio, overhead & throughput. In this Reactive routing protocols can spectacularly reduce routing overhead because they do not need to search for and maintain the routes on which there is no data traffic. This property is very invoking in the limited resource. Achieve a good efficient network life and reliability need a variation on the notion of multicasting. Geocasting is useful for sending messages to nodes in a specified geographical region. This region is called the geo-cast region. For geo-casting in mobile ad hoc networks. The proposed protocol combines any casting with local flooding to implement geo-casting. Thus, Protocol requires two phases for geo-casting. First, it performs any casting from a source to any node in the geo-cast region. Also this Protocol works on large MANET, and to achieve high accuracy and optimize output. To perform geo-cast region we use a proposed clustering technique in Large MANET.
