[hal-01202304] Low energy clustering adaptation protocol for an adhoc wireless sensor network

Energy dissipation in a Wireless Sensor Network is an active research field. Energy dissipation is related to the network topology and protocol used to route data. So, two criteria are proposed to elect a relay. A linear or a random choice from a set of potential nodes to become a relay based on their energy level above a mean threshold energy. These criteria improve the organization of the node communications and the lifetime of the network. The criteria and the protocol called the Self Organization One Hop Low Energy Clustering Adaptation (SOORLECA) are explained. The SOORLECA is designed for environmental and military monitoring with precise requisite measures at each node. No mean data or smoothing data technique is required at the Sink Node (SN). Random topology of the network for 100 nodes over 100m2 are simulated to show the protocol performances compared to direct transmission of the node to the SN, short routing path and static clustering protocols. The lifetime and the dissipated energy of the network are our criteria to measure the performance of the WSN. It is shown that the SOORLECA ACMET1 improves 2x the lifetime of network with 61% dissipated energy after 50% of nodes have dead.
