Abstract: Power and delay is a significant and essential issue, which in routing protocols for Wireless Sensor Networks (WSNs). Sensor nodes are broadcast in particular areas of the environment to identify events and establish WSN. These sensor nodes encompass limitations such as power, memory and computational capability. Since medium Access Control sub layer controls transmissions of the media and collisions, it has significant impact in reducing energy consumption and increasing the channel’s efficiency. Therefore, the medium Access Control sub-layer plays an important task in WSN. By allocating channel duty, media access control sub-layer can reduce collisions; these measures can reduce energy utilization and enlarge the productivity of the channel. In this proposed paper, an improved medium access control protocol is proposed based on clustering technique. Using a multi-layered approach, this technique is intended to reduce competition and traffic in the network. The proposed algorithm consists of two steps including clustering and data transferring of each cluster. The proposed approach can significantly reduce collision, sleep-delay and idle listening. Computer simulation approach is used to evaluate the proposed algorithm. The results of simulation shows the proposed protocol is more efficient than the other existing protocols like MLMAC in terms of the following features: number of successfully sent packets, number of collision, energy consumption and sleep delay.
