ABSTRACT="Mitigating Hot Spot energy consumption in Wireless Sensor
Networks (WSNs) is a demanding task. Hot Spots have their nature
strictly bounded with routing - they are areas overloaded with high
traffic rate, resulting in expanding energy holes. Hot Spots mitigation
approaches have employed several techniques supported by routing
protocols, such as multiple or mobile sinks, the deployment of more
sensors in the Hot Spot area and unequal clustering. Albeit their
advantages, cluster-based routing protocols to mitigate Hot Spots manage
route maintenance inefficiently, leading to poor network performance and
high energy consumption. This work presents an energy management
approach to mitigate Hot Spots in WSN, supported by unequal clustering
and low-costly dynamic route maintenance. We also generalize our
solution for an energy management architecture that considers Hot Spot
issues. Results show resilient routing and an efficient energy
management, improving both network lifetime and performance."
