Abstract

Sensor nodes are broadcast in particular areas of the environment to identify events and establish wireless sensor networks. These sensor nodes have 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 role in wireless sensor networks. By allocating channel duty, media access control sub-layer can reduce collisions these measures can reduce energy consumption and increase the productivity of the channel. In this 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. In order to evaluate the proposed algorithm computer simulation approach is used. The results of simulation show that the performance of the proposed protocol is more efficient than other existing protocols like ML-MAC in terms of the following features: number of successfully sent packets, number of collision, energy consumption and sleep-delay.
