— Clustering in wireless sensor networks (WSNs) is an important technique to ease topology management and routing. Clustering provides an effective method for prolonging lifetime of a WSN. This paper proposes energy efficient multi-level clustering schemes for wireless sensor networks. Wireless sensor nodes are extremely energy constrained with a limited(More)
Wireless Sensor Networks (WSNs) are generally believed to be homogeneous, but some sensor nodes of higher energy can be used to prolong the lifetime and reliability of WSNs. This gives birth to the concept of Heterogeneous Wireless Sensor Networks (HWSNs). Clustering is an important technique to prolong the lifetime of WSNs and to reduce energy consumption(More)
Wireless sensor networks (WSNs) do not always have sensor nodes of same type. In other words, WSNs are not always homogeneous, but some sensor nodes of higher energy can be used to prolong the lifetime and reliability of WSNs. Heterogeneous wireless sensor networks (HWSNs) have some sensor nodes of relatively higher energy. HWSNs are very useful in real(More)
