A wireless sensor network (WSN) consists of a huge number of sensor nodes that are inadequate in energy, storage and processing power. One of the major tasks of the sensor nodes is the collection of data and forwarding the gathered data to the base station (BS). Hence, the network lifetime becomes the major criteria for effective design of the data gathering schemes in WSN. In this paper, an energy-efficient...
Wireless sensor networks have been studied extensively for their broad range of applications, especially in an environment with no infrastructure. And the nodes failures, link errors, and malicious node attacks are likely to occur quite frequently in wireless sensor networks. It affects the stability and reliability of data transmission. In this paper, we present a security fault-tolerant routing...
