An energy-efficient topology construction algorithm for wireless sensor networks

Topology control is an efficiency method that can extend the network lifetime in a wireless sensor network. There are several researches involve the topology control problem. In this paper, we design an energy-efficient topology control algorithm both take into consider with topology construction and count infinity problem. In the topology construction, we build a reliable topology to reduce the packet retransmission. We use intermittently links and natural of wireless network. Each node can receive the packet, when it in someone’s coverage. Therefore, we combined these features to build a high network reachable probability. It can enhance the network efficiency. In addition to, we consider count infinity problem during the process of topology construction. Nodes can remove the redundant component to ensure avoiding count infinity. Our proposed method can obtain the high network reachable probability and to extend the network lifetime. Experiments indicate the superiority of the proposed algorithm in terms of average energy consumption and network lifetime.
