BSC-MAC: Energy efficiency in wireless sensor networks with base station control

Abstract

Wireless sensor networks (WSNs) are now used in many areas and the interest in this technology continues to increase. Due to the small structure of the processor, the memory of the sensor nodes forming the wireless sensor networks, and as they are operated by a battery, the most important problem appears to be the energy issue. The battery depletion of the sensor nodes randomly deployed in critical areas may negatively interfere with part or all of the network communication and may cause the life of the entire network to terminate. Therefore, many studies have been conducted in the field of energy efficiency. In this study, Base Station Controlled MAC (BSC-MAC), which is a new design of MAC, is recommended. The BSC-MAC protocol presents an adaptive approach for energy efficiency. It determines the nodes on the network as root and source nodes and manages a sleep schedule according to these structures. The simulation of the BSC-MAC protocol was performed with ns-2 and compared to similar protocols, such as adaptive energy efficient MAC (AEEMAC), pattern MAC (P-MAC), and sensor MAC (S-MAC).
