We present CARNIVORE a system for in situ unobtrusive monitoring of cryptic difficult-to-catch observe wildlife in their natural habitat. CARNIVORE is a network of mobile and static nodes with sensing processing storage and wireless communication capabilities. carnivore s compact low-power mobile animal-borne nodes collect sensor data and transmit it to static nodes which then relay it to the Internet. Depending on the wildlife being studied the network can be quite sparse and therefore disconnected frequently for arbitrarily long periods of time. To support disconnected operation CARNIVORE uses an opportunistic routing approach taking advantage of every encounter between nodes mobile-to-mobile and mobile-to-static to propagate data. With a lifespan of 50-100 days a CARNIVORE mobile node outfitted on a collar collects and transmits 1 GB of data compared to 450 kB of data from comparable .
