This presentation covers various characteristics of a wireless sensor
network in monitoring an unattended area. Results of how wireless
sensor network topologies can be effectively used for physically
accessible areas are presented. Minimizing packet traffic by collecting
data using a mobile Base Station is discussed, along with energy
consumption. An innovative technique of distributing keys for shared
secret key based communications is described, and various
characteristics including resiliency, and monitoring a battle-field
using wireless sensor networks are outlined. Analytical model is
introduced and compared with simulation results. The need for layered
sensing in secured communications is investigated.
