Performance of Triple Umpiring System and its Enhancements in Wireless Sensor Networks

Advances in Wireless Sensor Network Technology (WSN) has provided the availability of small and low-cost sensor with capability of sensing various types of physical and environmental conditions, data processing and wireless communication. One of the most challenging issues so far is the extension of network lifetime with regards to small battery capacity and self-sustained operation. Endeavors to save energy have been made on various frontiers, ranging from hardware improvements over medium access and routing protocols to network clustering and role changing strategies. In addition some authors studied failures in communication regarded as error detection. Yet, only weak attention has been paid to the detection of malicious nodes and its potential for lifetime extension. In this paper, we analyzed the performance of Triple Umpiring System and its enhancements to develop an Efficient and Secure Routing Protocol (ESRP) for WSN. Extensive investigation studies using Glomosim 2.03 simulator show that the proposed scheme helps to achieve balanced energy consumption and increases the throughput.
