  1. General Description

  2. Less impact on Less impact on sensing coverage sensing coverage More impact on More impact on sensing coverage sensing coverage Source Source Sensing Sensing Range Range Destination Destination Coverage-Preserving Routing Protocol for WSNs • Distributed, power-balanced multi-hop routing protocol • Coverage-preserving based route-selection algorithm • Achieve the best sensing performance and lifetime • LEACH based, virtual grid based and multi-hop based routing protocols • Implemented on Mica Mote platform

  3. A new link stability prediction method for shadowed environments A more realistic user mobility model and propagation model are considered Can be applied to the applications, such as link performance prediction, system performance analysis, service quality prediction and route search Link Stability Prediction for Mobile Ad Hoc Networks in Shadowed Environments

  4. Determine a random-deployment strategy to optimize the lifetime of the whole WSN Based on the expected power consumption of each sub-area in WSNs Non-uniform node density through the sensing area Consider WSNs with following protocols Cluster-based routing protocols Multihop-based routing protocols Lifetime-Based Random-Deployment for WSNs Multihop Routing Line Server Cluster-based routing (LEACH) Server
