摘要:A wireless sensor network (WSN) consists of distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, pressure, etc., [8] And to pass their data through the network to a main location.WSN are actively developing due to the potential applications such as habitat monitoring, tracking chemical plumes, smart transportation etc. But the low lifetime of the network batteries in sensor nodes and routing protocols directly affecting the life time of the network. Clustering is the technique preferred to reduce the energy consumption and extend the network life time. Clustering allows hierarchical structures to be built on the nodes and enables more efficient use of scarce resources such as frequency spectrum, bandwidth and power. Clustering also allows the health of the nto be monitored and misbehaving nodes to be identified, as some nodes in a cluster can play watchdog roles over other nodes. Many novel architectures, protocols, algorithms and applications have been proposed and implemented. This paper proposes an improved energy efficient clustering mechanisms for minimizing the energy consumption and a scheduling algorithm to reduce the packet transmission delay and packet loss
