The deployment of Wireless Sensor Network is becoming more common in a wide range of environments. Many applications that make use of Wireless Sensor Networks require secure communication. The author design and implement a protocol set which is known as LBDP (Location Based Direct Protocol) and LBIP (Location Based Indirect Protocol). Networks running on this suite can not only establish keys between nodes in the absence of a backhaul connection, but also take advantage of such resources when they become available. This is the first multimodal key establishment suggested for sensor networks. Last, the authors characterize this hybrid protocol through an extensive performance analysis and examination of the savings gained from code reuse.
