Hierarchical-Battery Aware Routing in Wireless Sensor Networks
Source: University of Texas
The Wireless Sensor Networks (WSN) have been envisioned to help in numerous monitoring applications. Pulsed battery discharge from the nodes prolongs the battery capacity as compared to constant discharge. Idle time between the pulses of discharge helps in recovering the discharged battery capacity. In the hierarchical routing protocol, cluster head nodes expend much higher energy than other nodes without any idle time. In this paper, the paper is proposing a Hierarchical-Battery Aware Routing (H-BAR) protocol for the WSNs. To make discharge from the nodes as pulsed as possible, role of cluster heads is changed periodically between the nodes. Battery recovery capacity depends on the remaining capacities of the battery.
