“…It is being used in optimization problems. The factors affecting energy consumption have been discussed in [16], such as routing path length, link reliability, aggregation, load balance (of nodes on shortest paths with low residual energy), or various sensor network design parameters. The Energy waste can be due to Idle listening (largest contribution due to lack of knowledge about packet transmissions), Packet collision (leads to retransmission), Message overhearing, Control packet overhead and Over-emitting (sending packet when destination is not ready).…”
