As more and more innovative applications of wireless sensor networks emerge, the need for deploying heterogeneous sensors for fine-grain monitoring of physical environments subjected to critical conditions rise rapidly. In this paper, we propose a novel hybrid forwarding technique based on geographical location with the assistance of gateway node to satisfy performance needs of such applications....
Addressing plays an important role in traditional networks but incurs much overhead for resource-constrained wireless sensor networks (WSNs).Therefore, address-free sensor network has been proposed by researchers. However, current data delivery schemes are mainly proposed for address-based sensor networks and can't be directly applied to the new architecture. In this paper, we propose an efficient...
Schemes for wireless sensor network addressing are mainly based on static sensor node address which is determined in the process of deployment. However, with the increase of the network size, it is getting difficult to allocate the addresses manually for a large number of nodes. Moreover, the static address scheme is not able to deal with the complex situation in the real world due to dynamic death...
