Reducing The Energy Consumed During Multihop Transmissions in Wireless Sensor Networks

Abstract:
Reducing energy consumption in Wireless Sensor Networks (WSN) is important in order to lengthen the network lifetime and reduce maintenance cost. Although its substantial contribution, the energy consumed to overhear is often omitted in energy calculations. However, here it is included to model the tradeoff between the expected number of transmissions, transmission range, number of hops, and overhearing, to discover the optimal distance between the nodes along the routing path. Our calculations show that to reduce energy consumption, the node should choose their successors close enough to prevent the expected number of transmissions from exceeding 1.4. The access protocol is Low Power Listening (LPL), and we also present a solution to reduce the energy consumption of the nodes that are crucial for maintaining an operational network, i.e., the nodes whose successor is the sink.
