In this paper discussed The Internet of things (IoT) express physical devices that are set with sensor nodes, working capability, and other technologies that anchor and sharing data with other devices and systems over the internet. The nodes do not use any infrastructure for communication, such as a base station and wired access point. A critical problem arises in wireless sensor networks is power consumption. Another problem arises in wireless sensor networks is hidden terminal and Exposed terminal problem which reduced the throughput and increases End to End delay .To solve the problems used Directional antennas which is enhancing the performance of CARMAC Protocol by imposing transmission and receiving GPS signals on the wireless sensor nodes. In proposed work increases the sectors of the directional antennas and can be used to solve hidden terminal and exposed terminal problem by using ECARMAC protocol for wireless sensor network.
