摘要

In this letter, a cross-layer cooperative routing algorithm is proposed for minimizing the collision probability subject to an end-to-end outage probability constraint. We develop a collision minimization algorithm by combining cooperative transmission, optimal power allocation, and route selection. The proposed cooperative routing algorithm, called minimum collision cooperative routing (MCCR), selects the route that causes minimum collision probability to other nodes in the network. Results show that MCCR can significantly reduce the collision probability compared with existing cooperative routing schemes.
