As the services have increased many fold with variety of data types pumped into network, which included multimedia and fast changing conditions. The problem of congestion has also increased and posing the threat to Network performance and degradation of throughput due to change in topology and drawbacks in routing algorithms. In this paper, two a new routing protocol Advanced Optimized Link State Routing (A- OLSR) has been proposed and performance has been evaluated on the basis of existing protocols. In this protocol the modifications have been done in OLSR protocol in terms of pause time, speed, CBR connections, which have been done by modifying frame format and simulation concepts. The performance of OLSR & A-OLSR have been analyzed using varying Pause time, Speed, CBR Connections & also by varying number of nodes to provide the qualitative assessment of the applicability of protocols in different scenarios. The simulations are carried out using the Qualnet 4.5 simulation tool, which is used to run ad hoc simulations. The performance of network by using this protocol has enhanced if compared with existing protocols of the same nature. The concept of the protocol is has been put for validation in various mobility and constrained conditions.
