In this paper, the authors present performance analysis of proactive routing protocols using TCP and UDP connection. This paper describes the Optimized Link State Routing (OLSR) and Destination Sequence Distance Vector (DSDV) protocol for mobile ad hoc networks. The protocol is an optimization of the classical link state algorithm tailored to the requirements of a mobile wireless LAN. The key concept used in the protocol is that of MultiPoint Relays (MPRs). MPRs are selected nodes which forward broadcast messages during the flooding process. This technique substantially reduces the message overhead as compared to a classical flooding mechanism, where every node retransmits each message when it receives the first copy of the message.
