These have the potential for use in the monitoring of railway signalingsystems and rail tracks. Energy efficiency is one of the most important design factors for the WSNs as the typical sensor nodes are equipped with limited power batteries. In earlier research, an energy-efficient cluster-based adaptive time-division multiple access(TDMA) medium-access-control (MAC) protocol, namedEA-TDMA, has been developed by the authors for the purpose of communication between the sensors placed in a railway wagon. This paper proposes another new protocol, named E-BMA, which achieves even better energy efficiency for low and medium traffic by minimizing the idle time during the contention period. In addition to railway applications, the EA-TDMA and E-BMA protocols are suitable for generic wireless data communication purposes. Both analytical and simulation results for the energy consumption of TDMA, EA-TDMA, BMA, and E-BMA have been presented in this paper to demonstrate the superiority of the EA-TDMA andE-BMA protocols. EXISTING SYSTEM: With the increased demand for railway services, railway monitoring systems continue to advance at a remarkable pace to maintain reliable, safe, and secure operation. The lack of safety and security monitoring of railway infrastructure runs the risk of train collision, train derailment, terrorist threats, and failures in the train wagons, etc.
  2. 2. The performance of rail vehicles running on tracks is limited by the lateral instability inherent to thedesign of the wagon’s steering and the response of the railway wagon to individual or combined track irregularities. Railway track irregularities need to be kept within safe operating marginsby undertaking appropriate maintenance programs. Track geometry inspection and monitoring enhances train-operating safety and reduced vehicle and track dynamic interaction. PROPOSED SYSTEM: In this project, we are going to implementing and monitoring using 2-wireless sensor network. And we can also use 3-wireless sensor network, using dotnet application and TCP/IP protocol to implementation and monitoring in railway application. The potential of WSN technology to monitor the railwaywagonhealth condition and the vertical displacement of railwaywagons due to track irregularities has yet to be fully explored.The limited lifetime of the batteries that power the sensor nodesmakes the energy efficiency a major design issue for WSNs. This paper concentrates on developing an energy-efficientWSN MAC protocol to collect data from sensor nodes that are placed inside the railway wagons and send the data tothe locomotive for further precautionary actions to prevent anyfuture disastrous events. Although theproposed energy-efficient protocol is designed with the railwayapplications in mind, it is applicable to generic wireless datacommunication purposes. HARDWARE REQURIMENT: 1.
