Mixed type logical topology for wireless sensor networks

WSNs (wireless sensor networks) are often high-densely deployed and nodes are easy to fail. All these uncertainty preclude manual configuration and design-time pre-configuration. In the paper, MTLT (mixed type logical topology) is proposed, by which the whole sensor network is organized as mixed-type logical topology according to the local density and energy constraint. Simulation experiments proved that MTLT is a simple, robust and low-latency topology for different types of data dissemination in dense deployed WSNs.
