This paper proposes a time slotted distributed protocol to enhance transmissions in ad-hoc networks. This is achieved by employing the well known cooperative virtual multiple input multiple output (MIMO) technique. A general protocol for N cooperating nodes is presented and evaluated considering bit error rate (BER), signal to noise ratio (SNR) and delay as target metrics. We show in particular that there is a trade off between performance, complexity and delay. Interestingly, reliable multimedia transmission can be achieved with reasonable delay constraints, as required in many telehealth applications.
