4. Result and analysis

The proposed ACO is implemented in Network Simulator 2 (NS2). The performance is tested in a variety of design and topology of network which include wired, wireless; in variety of network design which based on number of nodes; various load condition of network which is defined as normal load, medium load and heavy load; and using various transport protocol such TCP and UDP. Fig. 3 show the design of type 1 wired network, the Table 1 shows the various types of wired network used for the simulations. The simulation is implemented for 10 s. The throughput, response time and packet loss is calculated for entire 10 s and the mean value of each calculation is shown in the following tables. The average response time shown in the tables and figures are the combination of route discovery time, transmission time, propagation delay in each node, and waiting time in the intermediate queue. Table 2 shows the comparison of packet loss in proposed and existing routing protocol. Table 3 shows the comparison of routing packet size of each routing protocol. In which the ACO has lesser packet size which reduces the routing overhead and avoids traffic due to control packet. The packet size of SMACO is slight higher than ACO due to two more two structures are introduced in the SMACO which occupy 8bits each. Therefore the implementation not requires any control overhead. The higher the routing packet size may increase the routing overhead and involves unnecessary traffic due to control packets, whereas the objectives of this thesis are to obtain reduced p
