A slot assignment (or scheduling) in TDMA based wireless sensor networks (WSNs) considering energy efficiency, scalability and complexity is presented. The algorithm named DNIB is a new TDMA free collision distributed slot assignment algorithm for WSNs. DNIB relies on two-hop neighborhood information. Performance analysis and simulations show that DNIB is scalable and outperforms existing mechanisms.
