Abstract |
Wireless sensor networks can be used to collect surrounding data by multi-hop. As diversity of application requirement (energy-efficient centric or latency centric), energy efficiency and data latency are both important designing issues in designing a clustering scheme optimally. In this paper, the energy consumption of two basic clustering schemes is modeled and the impact of unreliable wireless link on sensor networks configuration is discussed. Then an alternate-hop clustering scheme is proposed, which is proven to be more energy-efficient theoretically. Further, the latency within a cluster is analyzed. At last we propose an optimal task-specific clustering scheme in unreliable wireless sensor networks. |
