Dual channel power controlled backoff based on geographic location in Ad Hoc networks

In this paper,an energy optimization with dual channel power controlled backoff based on geographic location is proposed.The basic idea is control channel backoff from low power to high power,data channel "backoff" from high to low.And using the benefit of geographic information,the problem of asymmetric links is solved better.In addition backoff algorithm is introduced and the successful transmission probability is analyzed briefly in this paper.The simulations result shows it can meet the design of Ad Hoc networks of short distance priority.
