An Optimal-Distance-Based Transmission Strategy for Lifetime Maximization of Wireless Sensor Networks

Abstract— An Optimal-Distance-Based Transmission Strategy for Lifetime Maximization of Wireless Sensor Networks. An effective transmission strategy plays a vital role in maximizing the lifetime of wireless sensor networks WSNs< Final Year Projects 2016 > To fulfill such a maximization aim, an optimal-distance-based transmission strategy is put forward on the basis of ant colony optimization (ACO). First, by introducing two notions, most energy-efficient distance and most energy-balanced distance, a local optimal-distance achievement mechanism is presented not only for a high energy efficiency, but also a good energy balancing in WSNs. Furthermore, by working out a network lifetime evaluation method, a global optimal-distance acquirement scheme is developed to achieve energy depletion minimization for sensor nodes with maximal energy consumption throughout the network.
