Abstract
The growing Internet of Things (IoT) is increasing wireless sensor networks (WSNs) for different applications. Energy efficiency and reliability are key factors for multi-hop path source to sink. A relay node forwards other node's data to sink, therefore, it consumes more energy. When relay runs out of battery it may cause network failure in WSNs of IoT. A relay selection in multi-hop transmission can play an important role to increase the network lifetime. A stable, WSN is the fundamental requirement for IoT data gathering in multi-hop networking from source to sink. In this paper, an energy efficient distributed relay selection (EDRS) technique is proposed for multi-hop WSNs. The energy consumption is reduced by selecting a stable relay and power allocation for collaboration. In addition, the proposed EDRS selects a relay node with optimal power levels to prolong the network lifetime. The simulation results demonstrate, the EDRS reduces energy consumption and increases network lifetime.
