摘要：There are different applications in wireless sensor networks, where sensors with different capacities are deployed. So designing a reliable and scalable routing protocol for a real world wireless heterogeneous sensor network is an interesting task. In this paper, we propose a novel power aware routing for wireless heterogeneous sensor network, which can provide loop less, stateless routing without using any prior neighborhood information. It utilizes both symmetric and asymmetric links to forward a data from source to sink. This protocol explores the neighbor node relations and chooses the best-hop based on node power. It eliminates the low-powered nodes to become hop- nodes in the contention process. It also prolongs the network lifetime. Analysis shows that this scheme significantly outperforms the existing protocol in wireless heterogeneous sensor networks.
