ENERGY BALANCED COMMUNICATION IN WIRELESS SENSOR NETWORKS

摘要

We propose threshold randomized routing (TRR) in multi-hop wireless sensor networks as a strategy for structured communication that provides a tradeoff among total energy consumption, total latency, and energy balance. Energy balance is a special concern because the collaborative nature of sensor network applications can render an energy-constrained sensor network useless if energy imbalance leads to a network partition. We evaluate the effectiveness of this strategy for worst-case and average-case permutation routing scenarios for a range of network sizes. This work is part of our effort to define a hierarchical methodology for application development for wireless sensor networks, based on energy-efficient communication and computation primitives that hide networking details from the application developer.
