This paper proposes novel energy efficient self-organization and medium access control (MAC) protocols for wireless sensor networks. The proposed protocol is based on time division multiple access (TDMA) principle and are referred to as TDMA. In the proposed protocol, a sensor utilizes its assigned slot only when it is sending or receiving information, otherwise its receiver and transmitter are turned off to avoid unnecessary neighbor listening. In order to accelerate the receive response, wake-up packets are used to activate a sleeping node. When compared with the existing energy efficient MAC protocols, such as 10% S-MAC, the performance results show that the proposed TDMA-W protocol consumes only 1.5% to 15% of the S-MAC power, yielding 6 to 67 folds enhancement in battery life.
