Abstract
Wireless Sensor Network (WSN) applications frequently require different objectives, such as reliability, timely communication and longevity. To cope with that, a WSN can be conceived with multiple sinks and routing protocols designed over different communication schemes. In this paper, we address the communication latency and the network lifetime issues in Multi-Sink WSN deployment. We propose GeoK, a k-anycast geographic routing protocol that considers a linear combination of network metrics during the decision process of the next hop. Packets are forwarded over exactly k sinks, with targets and duplications being defined on the fly. Simulation results show a better performance for GeoK, with improvements of approximately 13% for the average latency, and 30% for the maximum energy consumption, compared to existing work.
