Performance Evaluation of Probabilistic Next-Hop Selection in Intermittent Wireless Multihop Sensor Networks

Abstract

Wireless sensor networks are expected to be critical platforms for IoT systems consisting of various wireless sensor nodes without continuous battery power supply. Due to limited transmission power, wireless multihop transmissions of sensor data messages to the sink node are mandatory. Thus, low-power forwarding based on intermittent communication in each intermediate wireless sensor node is required. However, it is difficult for intermediate wireless sensor nodes to select their next-hop node since on-off intervals and current locations of their neighbor wireless sensor nodes are not always achieved due to the intermittent communication environments. This paper proposes a novel probabilistic next-hop selection and evaluates the performance improvement, i.e., reduction of transmission delay and battery power consumption.
