In this paper we will propose a relaying scheme for wireless multi-hop networks. It is based on collaboration of intermediate relays at network layer to forward useful side information in place of dumbly forwarding packets. In our scheme we assume that the nodes are not able to benefit from any interference cancellation mechanism. The channels from sender to relay nodes and from sender to receiver are logically separated through a temporal scheduling. This model is realistic for many practical scenarios in the context of wireless networks. We will show in this paper the information theoretic bounds and show that they are achievable using practical codes. The proposed coding scheme is simulated in realistic scenarios. The obtained results show a remarkable improvement in throughput, relay load and reliability compared to network using classical routing approach.
