摘要：A Wireless Sensor Network (WSN) is a network that contains numerous sensor nodes for gaining information from the environment and to communicate with other sensor nodes. In this work, we propose to increase the lifetime of a network by trust level computation and Ant Colony Optimization (ACO) algorithm for routing. Initially, the trust level of nodes is computed by the one hop neighbour and then the optimal route is selected by the ACO algorithm. The trust level of nodes is calculated by taking energy and packet delivery ratio into account. Thus, the transmission is made fast and the energy is effectively utilized, which in turn increases the lifetime of the network. This system proves maximum energy efficiency and minimum energy consumption, which is shown in experimental analysis.
