AD Hoc networks differ from traditional net-works in several ways: sensor networks have severe en-ergy constraints, redundant low-rate data, and many-to-one flows. The end-to-end routing schemes that have been pro-posed in the literature for mobile ad-hoc networks are not appropriate under these settings.
