ABSTRACT
The energy efficiency of a wireless sensor network (WSN) is one of the most critical requirements in WSNs. Due to limited energy resources, network lifetime is one of the critical issues as well. The passive (switched off) extra nodes are ready to become active (be switched on) when any active WSN node uses up its energy. This results in extending WSN lifetime. We propose the enhancement in LEACH protocol , which modifies the prominent LEACH protocol by electing a new Cluster Head (CH) before the existing cluster head dies. The enhancement is realized by adding a phase where existing CH advertises its low energy status to cluster members. The cluster members check their own energy levels. If the member's energy is above a predefined threshold then that member can elect itself as a new CH. This enhancement increases energy efficiency for WSNs, thus extending WSN lifetime.
