DRMACSN : New MAC protocol for Wireless Sensor Networks

— In this paper, we propose a new distributed, load balanced, and route aware medium access control protocol for Code Division Multiple Access (CDMA) based Wireless sensor networks (DRMACSN). Wireless Sensor networks (WSN), is new class of devices, have the potential to revolutionize the capturing, processing, and communication of critical data by first responders. Sensor networks consist of small, low-power, and low-cost devices with limited computational and wireless communication capabilities. They represent the next step in wireless communication's miniaturization, and their power and size make it feasible to embed them into wearable vital sign monitors, location-tracking tags in buildings, and first responder uniform gear. The sensor nodes can only transmit a finite number of bits before they run out of energy. Thus, reducing the energy consumption per bit for end-to-end data transmission is an important design consideration for such networks. We show how our design would improve the MAC protocol with sleep and wakeup schemes that could achieve greater energy savings, reliability and increased system capacity. In this paper, we present findings for the delay, and the throughput of the proposed MAC protocol.
