This paper presents the assessment results and findings of the simulation infrastructure project using OPNET have been developed and implemented to cover the protocols and design issues of the wireless MANET architect with minimum overlaps. All the nodes (devices) are wireless, mobile and equal (no access points, base stations, or any other kind of infrastructure). The concept of the mobile ad-hoc network suggests the incorporation of routing functionality into mobile nodes, in other words all nodes should be able to act as routers for each other. This network is self-configuring and can have dynamically changing multi-hop topologies, composed of, likely, bandwidth constrained wireless links. Optimized Link State Routing (OLSR) protocol for mobile and wireless ad hoc networks was integrated in a commercial routing stack suite. OLSR operation mainly consists of updating and maintaining information in routing tables. The data in these tables is based on received control traffic and the control traffic is generated based on information retrieved from the tables. The optimization is based on a technique called MultiPoint Relaying. The simulation model on OPNET was configured and simulated to address the challenges of OLSR implementation with various topologies, especially the environment to meet the following key points: a) planning of node movements, b) dynamic status of network topology and connectivity (map or canvas based), c) operational planning based on communication conditions, and d) planning of the communications infrastructure.. The project results in best settings for our network and can predict the cost, traffic behaviours, throughput and efficiency of the network beforehand.
