ABSTRACT

Ad-hoc networks are a new wireless networking paradigm for mobile hosts. Ad hoc networks don't require any fixed infrastructure such as base stations or mobile switching centers. Node mobility in an ad-hoc network causes frequent changes of the network topology. Routing protocols are used to discover routes between the nodes. Many mobile ad-hoc networks protocols such as AODV construct route only when desired by the source node. This paper maintains prior history information about the mobility of node in Ad-hoc network. Every path that is inserted into route table must be analyzed and assign a weightage factor to that path. If weightage factor of path is greater than given threshold value, insert this path in a separate fast route table. The targeted characteristics are: reduce searching time and provide good connectivity.
