This paper presents a tree-based energy efficient and collision free MAC in Wireless sensor networks (WSNs). Exploiting the routing tree formed in many-to-one based data dissemination of WSNs, a TDMA scheduling is proposed for nodes wake-up and reception. The scheme is simulated using ns-2 which shows its effectiveness. . Introduction 1 The rapid proliferation of miniature wireless networking technologies [1] drives to devise different sensor network applications with diverse QoS requirements. Achieving higher reliability is one of the major requirements for
