Abstract
A Wireless Sensor Network (WSN) is composed of sensors that communicate together in a distributed way to supervise the environment. The energy consumption is an important performance measure for a WSN that spurs the development of energy-efficient distributed algorithms for WSNs. In this field, we focus on a specific type of distributed algorithms called handshake. A handshake algorithm allows making two sensors communicate safely by ensuring that they communicate together in an exclusive mode. In this paper, we propose a new energy-efficient WSN Handshake algorithm (WSN-HS). We present an evaluation of our algorithm compared to another similar one. The simulation results show that when using our WSN-HS, we can save the energy of the sensors and minimise the total number of exchanged messages. Alongside with its energy efficiency, our algorithm is fault-tolerant. Hence, we make the disappearance of some sensors caused by their energy depletion not blocking for other sensors.
