Performance evaluation of routing with ARC congested node over BTSnet for mobile ad hoc networks and inter-vehicular communications

In this paper the new algorithm to improve the performance of data delivery percentage over Bangkok Train System Network (BTSnet) is presented. BTSnet can be implemented in regular traffic patterns by the public transportation authority to improve the performance of mobile ad hoc networks (MANET) for inter-vehicular communication systems (IVCS) in Bangkok. Since ad hoc networks consist of mobile nodes that are randomly moving and unpredictable, IVCS can provide users with a range of services. The implementation of IVCS is possible using MANET. Some places are congested and drop-packets occurred and it will be degrading performance. The proposed algorithm improves the performance by adjusting data transmission rate, rather than fixed rate, after the collection of current number of packet drop, data rate and packet delay time. Several simulations are performed by NS-2 simulations under the congested situation then our proposed algorithm results are compared to ones from traditional method. Results from each BTS-Train scenario will be simulated under the traffic situation in the geographical area of Bangkok. We found impressive results that support our algorithm
